Hi everyone. Jianyi mentioned in one of his posts that he lives in Olds, Alberta. I live in Lethbridge, Alberta, 3 1/2 hours South of Jianyi. I contacted him to see if we could tour his greenhouse and he was VERY accommodating.. We saw it yesterday, Feb 16th, 2021.. It is amazing. After 2 solid weeks of daytime high temperatures between -20C and -35C the temperature inside his greenhouse was still 16 degrees ABOVE zero. NOTE that the past 2 weeks was a bit unusual for temperatures in our area. I know many think we live in igloos year round, but two weeks of subzero was definitely unusual. It's really a great way to build a greenhouse. Jianyi was very hospitable and suggested we should come back in the summer when his crops are in full bloom. I REALLY thank him for welcoming us and wish him well in the future.
Really I’m surprised I contacted him about ordering 4 greenhouses like his he contacts me asks me for my number and then never contacts me again . Totally shuns me for no reason just like a real dickhead
@@1Ascanius The greenhouse on the video looks like a prototype and he is still in a phase of figuring things out. If some random dude contacted me that he wants 4times something that I am still prototyping based on the youtube video, I would instantly decline, because I don't have processes ready to build these things for other people. He wants to be focusing on efficiency of the produce, not building it for other people. Didn't that cross your mind? Oh and when somebody is not calling you, maybe you should give them a call, because... you know, maybe they forgot. You are not the center of the universe, dickhead.

Mr. Jianyi, my father in law, who is from Peace River, Alberta (North of Edmonton I believe), and also Chinese, tells me how much he loved the cold. As someone who loves plants, personally, and been to Calgary, it is amazing to see your hard work on the greenhouse and growing in Canadian weather! Keep on keepin on
You are amazing, Alberta needs more brave people like you. I believed that the govt should give more attention in food producion locally to employ people and create home grown food and economy.
Amazing! Wow!! I’m also in AB and was researching on building a straw bale north wall to a new build passive greenhouse! Your work is amazing!! Keep on teaching us what is possible!!
This is great! I'm planning to start a homestead in the next few years and looking forward to building some smaller scale passive solar greenhouses in Zone 5. I love seeing examples like this of what possible. I love seeing examples like this. Great to know that even a simple system like this without geothermal can maintain a year round nearly frost free area in my climate!
Wow, speechless. THAT is exactly what I want to do. Plants love me and I love plants. Especially food and it creates peace and harmony in my life, when ever I work with them. I live in Edmonton and we are saving up for a piece of land to start a Greenhouse. I already played around with ideas in the backyard and the house.

Bug fun fact: There are over 450 species of native Ladybug in North America... and one of them, Hippodamia convergens , is a heck of a beneficial for greenhouses and gardens looking for a natural way to fight pest bugs... especially aphids.
I think geothermal would work pretty well to avoid the temperature dipping below 0°c. There’s a video titled Nebraska retiree uses Earths heat to grow oranges in snow, he explains how he has pipes under ground 8ft deep which out puts air temperature at 52°f or 11°c no matter the time of year and outside temperature, it could mean you could take the insulating layer off the green house more often even on cloudy days meaning it would grow the plants faster.
@@greensfarmland it might cost a fair amount, could find cheaper ways to build it but this guy seems to spend a lot on money on his greenhouses and he even suggested doing it in this video so it can’t be completely out of the question.

I take my hat off to Canadian farmers. Over near Leamington, Ontario, the farmers do an amazing amount of greenhouse farming; just across the border, we don’t see this much at all.
That's an excellent greenhouse. I've been looking to do something like this but on a much smaller scale. I've seen many people use PVC rain barrels painted black and filled with water to absorb heat from the sun. Water holds over 40 times the heat energy of concrete or stone. Also there's a lot of people using "passive Geothermal". Just drainage pipe under ground below the frostline with a fan. Takes a lot of heat out of the ground in winter, and put's heat into the ground in summer. Also takes excess moisture out of the air.
Great design! I'm hoping to implement this design with geothermal this year for a family sized greenhouse in Ontario. The coldest temp we've had in my area is -17 this year so far, I think your design would work well!
Good man, new ideas. Incorporated some of this ideas building my own new hose in Toronto back in 1990. No windows facing north. All windows facing east, west , majority south. Clay floor tiles act as day sunlight heat absorbent. Throw in 2000 built year round solar water heating system.
Excellent video. A few well placed insulated light tubes with a good light diffuser on inside may give decent lighting on cold days when you have to keep the insulated tarps on.
You got a new sub today brother! Wow, what a greenhouse! I am jealous! I just want a 40x12! I started growing tomatoes 3 years ago, last year I grew 18 different varieties. I am just small time for my family only right now, but I hope to make a business someday. Cant wait to see this greenhouse active when it warms up!
the most important in a winter greenhouse the soil dont have to freeze the air is OK for harvest cold vege. Here in Laval, Québec I have only a 220 feets greenhouse and the soil is not freeze now in february it is ready to put seed in the soil for spring harvest before tomatoes.
very good informative video. Thank you. Here in this corner of scandinavia where we are at, it won't get as cold as in your part of canada. Your greenhouse would do amazing here. Good luck with your growings!
@@Concojone5 Hey Concojone5, the part of Europe we live in isn't as gloomy overcast as you might think. If it is mild it can be overcast in winter. if it is really cold the sun is out too.
Looks good. I grew cabbage over the winter last year(2019-2020) as an experiment also. I kept it from freezing hard enough to kill it, but not well enough to keep it from bolting right away and going to seed. It never formed a head. But it was only an experiment and still considered it a success. Good luck!
I have to say I'm a "make lemonade out of sour lemons" type lady and when my big cole crops rush to seed on me I let them and I take all that seed and use it in dead of winter to make microgreens! Nothing goes to waste lol. I already have several LED grow lamps so it was such a quick step to put two and two together and make someone yummy put of a oops that one went to seed. Lol.
@@douglaskattau9241 I like to keep most of my seeds pure but sometimes when I just want them for microgreens or just sprouts I don't bother. But I've had a few fun crosses grow out over the years. I figure that is how they got to most of our veggies through breeding selectively its kinda fun to be surprised. Happy gardening Douglas.
Amazing work! I just watched all your videos and can't wait to see more! I understand you have almost no expenses, apart from lighting for seedlings and preheating water and I would very much like to know in how much time you think you can pay-back the whole greenhouse! If you could do a financial overview of your whole project, I would be very much appreciated! Take care and cheers!
I have an industrial greenhouse in Montana and can grow year round to supply local restaurants. My solution was using ambient ground temperature to heat the greenhouse. I essentially dug 10 feet down and then domed the area off. Google Walopini to get an idea of what it looks like. Its easy to build into the mountain side and highly cost effective. Even when its -10 outside inside my walopini its a comfortable 30 degrees.
Very nice, I am very impressed with your system. This has to be one of the most efficient and cost effect systems in a northern climate out there. We have five 100ft high tunnels here in Alaska and I have been experimenting for years with wood stoves and ground heat. Just like your were saying, there is just no way to cost effectively add supplemental heat to these high tunnels in this northern climate . This coming spring I need to rebuild one of our wind damaged tunnels and I was planning on adding a small greenhouse within a green house similar to what you have. My thought was that if I kept the space small enough I could add heat and lights and use the new space to start the seasons seedlings and starts. Our primary income was from tomatoes and strawberries. During a normal hot summer we average around 2500 lbs of heirloom tomatoes per green house. I would love to hear about your production levels
Amazing work, thank you for sharing these updates! I'm curious if you have considered growing citrus? If your maximum low is -2c some of the hardier citrus types like Improved Meyer Lemon, Yuzu, Dekopon, Mandarin may be able to overwinter inside the greenhouse. Also maybe figs, pomegranate, olives, feijoa/pineapple-guava, etc
@@dongjianyi2492 You're welcome! For some inspiration check out the youtube channel "Jane Squier" from Vancouver, and Kirsten Dirksen's video on Russ Finch's "Greenhouse in the Snow" in Nebraska, USA. Both growing lots of citrus in cold climate (although not quite as cold as yours!).
As a secondary heat source, you could make a boiler to heat water burning colza straw, or even wheat straw, then use The heated water to heat the greenhouse. I've seen one builted from a 20 ton water tank, Power 500 KW. Very cost efective,The most simple and cheap heating solution.Thank you for sharing this Information.
Hi , I live in Castlegar BC , Im 71, And my first Job was a Greenhouse in Montreal They sold Retail plants ect . They had a big old pizza oven And they would dry tomatoes onions and Herb all day and night and sold all over Montreal The oven heated whole greenhouse . may work for you . I also saw a guy that had a kiln and made clay things , They sold the vases ect at a farmers market along with the produce they grew it warmed up the green house also .
What about adding more thermal mass to the system? A few big water tanks along the north wall - each holding a cubic meter would resist temperature drops overnight Should be cheap too - and also give you a bit of resilience if you have any interruptions to your water supply?
Watch his other clip. That black wall you are talking about is 1m (3.3feet) thick and made of clay, and 100m (300feet) long and you can see the height in the clip. That's the whole solar battery that's keeping this greenhouse warm. A few drums, will make no difference in such a vast space especially compared to that wall. 3.3feet x 300 feet x 6 feet (probably in height) = that's 6000 cubic feet of clay painted black :) - about 200 of those cubic meter water tanks.
Considering it was -30 degrees (very rarely gets that cold) but 22 degrees in the greenhouse he doesn't have to do anything he isn't already doing with passive solar.
This is pretty amazing. I live in Winnipeg, Manitoba and our temperatures are very similar. I wish I had the yard space to just have a small greenhouse. I do mainly raised beds as I just don't have the space to do anything else. I think it would be pretty neat if there was a way you could track both the outside and inside temperatures over the course of a year and graph them out to see how they look.
I think geothermal could be an economical option if done right when building the new greenhouses. If you rented a tractor-sized trencher you could trench about 5 feet down and lay pvc pipe down the middle length of each house, with smaller pipes T-d out every 25-50 feet or so. That way one blower at one end of the house could force air through the pipes to circulate air in the whole greenhouse. You wouldn't get as much warming as you would with a 40 foot deep pipe, but it should be enough to keep it above freezing. The slightly warmer temperatures might also help the vegetables grow faster, which could make the difference in whether or not it is economical for you. Just a thought.
Thanks for sharing. I used wood chips in our southern Alberta greenhouse 25,000 square feet. They were primarily softwood chips. I had used peat and manure but found chips to be the best. I used water soluble fertilizer but no pesticides ever. We collected our own predators and bought when the weather was bad. I noticed a lot of salt or calcium crust on top of your soil. Are you using foliar or soil tests? You can contact me directly if you like. I've been in the horticulture business over 35 years and have had three greenhouse companies. So I've made my share of mistakes.
I think the stuff you're doing here is amazing -- but if you haven't already, you should check out what some of the folks are doing in Maine, Vermont, and Ontario (ex. Eliot Coleman + Connor Crickmore). They're doing similar stuff with even lower-tech greenhouses and really maximizing space utilization. I also grow year-round in my greenhouses, and with appropriate timing I earn a living wage all winter with unmodified double-layer-inflated greenhouses (Southern Ontario, Zone 5b). Tomatoes decline in profitability as the light decreases, whereas winter greens aren't affected nearly as much. Cutting the tomatoes out earlier could give you more time to establish profitable winter greens crops that would keep the revenue stream more consistent across the year. Amazing stuff you're doing!
.......I've been to Calgary and I know those winters with plenty bright sunshine but extremely cold and very dry . In Eyre peninsula here in the antipodies down under there are greenhouses designed for evaporation/distillation of seawater and cooling making use of prevailing winds for evaporative cooling. Tomatoes is the main cash crop .The land is dirt cheap and nothing else much grows if not for the greenhouse setups . It's been introduced into Somalia also , they had some famines last fee years so this system is a big help for them . In southeast Spain it's almost nothing but these greenhouses everywhere . Strawberries is another favoured cash crop cos strawberries are in heaps of nice things . On a smaller scale folk can experiment with transparent forklift wrap rolls of that clear polyethylene plastic film wound around a big framework ,, be mindful of wind strength,, .On channel of odvoko he shows what he constructed this method .
I wonder how well -- 55 gallon barrels filled with water.... BUT....buried under the growing beds. Would do for your setup. Its great heat storage method Dig out one bed at a time.. Install the water barrels put the soil back and use as before. If you can, add tubing to circulate from the top of the greenhouse through the barrels during the summer. Heat exchanger style, (not mixing the barrel water with the circulation water) Don't circulate during winter. Your free summer temperatures/btu's will be saved for later use. It would be awesome to see how it works so far north.
Thanks again for posting these videos. I I wonder if you would be willing to give us a ballpark cost of this type greenhouse ? I appreciate you taking the time to make these videos hopefully it will help someone else be successful
@@dongjianyi2492 Thank you for the very useful information. Some great videos in the future might be a time lapse video of the construction of one of these greenhouses and / or an explanation as to how much labor and skill goes into assembling all the parts that come from China. It would also be interesting to know if smaller greenhouses are available. For example perhaps a 5000 sf greenhouse that requires half of the steel supports. Loving your videos. Keep up the fantastic work! :-)
Would you be willing to share with us where you purchase this style of greenhouse and where it is shipped from? Does this cost also include installation?
GREAT video! A few quick questions: 1. What is your current USDA Hardiness Zone, and what is the same question for inside the greenhouse? 2. Can you go into some details on the thermal blanket please? What kind of material is it, and how is it deployed? What kind of tracks is it on? 3. The "top layer" of the greenhouse looks like it is loose and flapping in the wind. Is this correct, or is this the camera playing tricks on the viewer?
1. I am at zone 3b. Not sure what it is in the greenhouse. It is warm inside but still has very little sunlight in winter. 2.The insulated blankets are made of polyester fabric. It is rolled up and down by an electric motor. 3.The top layer is not too loose. But the plastic does expand as I have been using it for 2.5 years. Better to tighten it again. But currently it is not too bad.
@@dongjianyi2492 thank you!! Would you mind doing a video of the system that winds/unwinds the thermal blanket? I am extremely interested in understanding the intracacies on how this works
Being on low budget - how do you deal with bacteria in soil and illnesses hitting your crops? Industrially the grow medium/soil would need to be replaced every so often. Thanks for your videos!
as far as heating a greenhouse for commercial vegetables goes, it would be great to have access to waste heat from energy intensive industries, but barring access to that, going passive is probably the best way to go.
This is wonderful to see, and very pleased to see your success growing in such difficult conditions. Do you have any concerns for high winds with this design?
Double wall polycarbonate panel greenhouses don't loose heat like plastic sheet ones but are more expensive per panel to build, worth the money in the long run though because of the R value.
I would love to do a simulation of this type of greenhouse, do spectral optimization of the foil to maximise light coming in, squeeze the last few percent of performance out of this design. Maybe if one day vacuum panels become cheaper you can have even less temperature loss at night. Inspiring video.
Simple Solution to Income . 1. Simply plant high THC Marijuana in the Greenhouse at one end . The profits alone from MJ will pay the Bills for the entire year with the Greenhouse and you can select grow other crops at leisure while you get 3 MJ Crops every year from it .
I have a high tunnel in Homer Alaska and I started my peppers and tomatoes this week. I normally have them started Feb. 1. I will plant them out into the big greenhouse in April. I did not see any air circulation fans. Is air moisture and condensation a problem for you?
Hello from just south of you in MT! Wondering how you deal with cooling in the summer. I love this concept for a greenhouse, but I can imagine it would get really hot in there really fast without some pretty serious ventilation. My greenhouse will easily get to 55°C if I'm not careful.
@@dongjianyi2492 Very interesting. Thanks for your response! I've since watched your webinar video and you answered the question there. It's so cool to see this design. I've been dreaming about almost this exact design for a couple years, but I'd never seen it before. Only difference is I'm not on the flat land, so I want to build it into a hillside. 👍👍

Excellent video. A few well placed insulated light tubes with a good light diffuser on inside may give decent lighting on cold days when you have to keep the insulated tarps on.
Good start, this will help us in the future for humanity. If not just 6 months but for long period of time. 👍👍👍
Merci from Montreal, Quebec.
You got a new sub today brother! Wow, what a greenhouse! I am jealous! I just want a 40x12! I started growing tomatoes 3 years ago, last year I grew 18 different varieties. I am just small time for my family only right now, but I hope to make a business someday. Cant wait to see this greenhouse active when it warms up!
So awesome! Didn't know you had a youtube channel until it was posted in YA. ;-) Thanks for sharing Jianyi!!
Just started to share these videos. What is YA?

Glad to see an update, I was curious to see how your greenhouse would handle the cold we've had recently
Amazing results. I really like how you criss-crossed those sticks over the plants to support the plastic. What are the sticks made of?
the most important in a winter greenhouse the soil dont have to freeze the air is OK for harvest cold vege. Here in Laval, Québec I have only a 220 feets greenhouse and the soil is not freeze now in february it is ready to put seed in the soil for spring harvest before tomatoes.
very good informative video. Thank you. Here in this corner of scandinavia where we are at, it won't get as cold as in your part of canada. Your greenhouse would do amazing here. Good luck with your growings!
Thanks
This type of greenhouse is ideal for sunny winters. They are used in China for a reason. I wonder what would work in gloomy overcast Europe.
@@Concojone5 Hey Concojone5, the part of Europe we live in isn't as gloomy overcast as you might think. If it is mild it can be overcast in winter. if it is really cold the sun is out too.
Looks good. I grew cabbage over the winter last year(2019-2020) as an experiment also. I kept it from freezing hard enough to kill it, but not well enough to keep it from bolting right away and going to seed. It never formed a head. But it was only an experiment and still considered it a success. Good luck!
I have to say I'm a "make lemonade out of sour lemons" type lady and when my big cole crops rush to seed on me I let them and I take all that seed and use it in dead of winter to make microgreens! Nothing goes to waste lol. I already have several LED grow lamps so it was such a quick step to put two and two together and make someone yummy put of a oops that one went to seed. Lol.
@@Emeraldwitch30, I saved some seeds as well.
@@douglaskattau9241 I like to keep most of my seeds pure but sometimes when I just want them for microgreens or just sprouts I don't bother. But I've had a few fun crosses grow out over the years.
I figure that is how they got to most of our veggies through breeding selectively its kinda fun to be surprised. Happy gardening Douglas.
The person who hit the thumbs down button obviously just missed the thumbs up button👍
...and thank you for making these videos!
Amazing work! I just watched all your videos and can't wait to see more! I understand you have almost no expenses, apart from lighting for seedlings and preheating water and I would very much like to know in how much time you think you can pay-back the whole greenhouse! If you could do a financial overview of your whole project, I would be very much appreciated! Take care and cheers!
In 2 years. I will share videos on my tomatoes. You will see how profitable it is.
I have an industrial greenhouse in Montana and can grow year round to supply local restaurants. My solution was using ambient ground temperature to heat the greenhouse. I essentially dug 10 feet down and then domed the area off. Google Walopini to get an idea of what it looks like. Its easy to build into the mountain side and highly cost effective. Even when its -10 outside inside my walopini its a comfortable 30 degrees.
Sounds great!
Love your comment. I'm looking at doing this on my farm in Northern Vermont near the Quebec border. Do you have any more information on your build?
you mean all that in Fahrenheits correct?
Also, isnt lack of Light for the plants (when u dig 10 feet down) a problem?
You are a determined man! Good work, I know it's hard.
Very nice, I am very impressed with your system. This has to be one of the most efficient and cost effect systems in a northern climate out there. We have five 100ft high tunnels here in Alaska and I have been experimenting for years with wood stoves and ground heat. Just like your were saying, there is just no way to cost effectively add supplemental heat to these high tunnels in this northern climate . This coming spring I need to rebuild one of our wind damaged tunnels and I was planning on adding a small greenhouse within a green house similar to what you have. My thought was that if I kept the space small enough I could add heat and lights and use the new space to start the seasons seedlings and starts. Our primary income was from tomatoes and strawberries. During a normal hot summer we average around 2500 lbs of heirloom tomatoes per green house. I would love to hear about your production levels
Thanks for sharing. I will share videos on my tomatoes in summer
Where can I find seeds to grow those chairs and the table? 😁
Thank you for sharing your experience!
Thanks:)
Ask seeds in IKEA :)
Amazing work, thank you for sharing these updates!
I'm curious if you have considered growing citrus? If your maximum low is -2c some of the hardier citrus types like Improved Meyer Lemon, Yuzu, Dekopon, Mandarin may be able to overwinter inside the greenhouse. Also maybe figs, pomegranate, olives, feijoa/pineapple-guava, etc
Thanks for the suggestion. I might try some trees in my second greenhouse
@@dongjianyi2492 You're welcome! For some inspiration check out the youtube channel "Jane Squier" from Vancouver, and Kirsten Dirksen's video on Russ Finch's "Greenhouse in the Snow" in Nebraska, USA. Both growing lots of citrus in cold climate (although not quite as cold as yours!).
@@paulyounger1190 Thanks
As a secondary heat source, you could make a boiler to heat water burning colza straw, or even wheat straw, then use The heated water to heat the greenhouse. I've seen one builted from a 20 ton water tank, Power 500 KW. Very cost efective,The most simple and cheap heating solution.Thank you for sharing this Information.
Great work, thank you for sharing. Is the ground insulated, how?
Trench 4ft deep around greenhouse and put sterofoam
Hi , I live in Castlegar BC , Im 71, And my first Job was a Greenhouse in Montreal They sold Retail plants ect . They had a big old pizza oven And they would dry tomatoes onions and Herb all day and night and sold all over Montreal The oven heated whole greenhouse . may work for you . I also saw a guy that had a kiln and made clay things , They sold the vases ect at a farmers market along with the produce they grew it warmed up the green house also .
Would love to see step by step instructional videos as you build your next green house.
What about adding more thermal mass to the system? A few big water tanks along the north wall - each holding a cubic meter would resist temperature drops overnight
Should be cheap too - and also give you a bit of resilience if you have any interruptions to your water supply?
Watch his other clip. That black wall you are talking about is 1m (3.3feet) thick and made of clay, and 100m (300feet) long and you can see the height in the clip. That's the whole solar battery that's keeping this greenhouse warm. A few drums, will make no difference in such a vast space especially compared to that wall. 3.3feet x 300 feet x 6 feet (probably in height) = that's 6000 cubic feet of clay painted black :) - about 200 of those cubic meter water tanks.
Considering it was -30 degrees (very rarely gets that cold) but 22 degrees in the greenhouse he doesn't have to do anything he isn't already doing with passive solar.
This is pretty amazing. I live in Winnipeg, Manitoba and our temperatures are very similar. I wish I had the yard space to just have a small greenhouse. I do mainly raised beds as I just don't have the space to do anything else.
I think it would be pretty neat if there was a way you could track both the outside and inside temperatures over the course of a year and graph them out to see how they look.
I have a part of the temp record in this video: th-cam.com/video/pXPakvPzgpE/w-d-xo.html
great video Thank you
I think geothermal could be an economical option if done right when building the new greenhouses. If you rented a tractor-sized trencher you could trench about 5 feet down and lay pvc pipe down the middle length of each house, with smaller pipes T-d out every 25-50 feet or so. That way one blower at one end of the house could force air through the pipes to circulate air in the whole greenhouse. You wouldn't get as much warming as you would with a 40 foot deep pipe, but it should be enough to keep it above freezing.
The slightly warmer temperatures might also help the vegetables grow faster, which could make the difference in whether or not it is economical for you. Just a thought.
Thanks for the suggestion. May try geothermal in the future:)
How to manage irrigation in winter or what's costing of your green house?
Thanks for sharing. I used wood chips in our southern Alberta greenhouse 25,000 square feet. They were primarily softwood chips. I had used peat and manure but found chips to be the best. I used water soluble fertilizer but no pesticides ever. We collected our own predators and bought when the weather was bad.
I noticed a lot of salt or calcium crust on top of your soil. Are you using foliar or soil tests? You can contact me directly if you like. I've been in the horticulture business over 35 years and have had three greenhouse companies. So I've made my share of mistakes.
Great. Thanks. May I know your email?
I think the stuff you're doing here is amazing -- but if you haven't already, you should check out what some of the folks are doing in Maine, Vermont, and Ontario (ex. Eliot Coleman + Connor Crickmore). They're doing similar stuff with even lower-tech greenhouses and really maximizing space utilization. I also grow year-round in my greenhouses, and with appropriate timing I earn a living wage all winter with unmodified double-layer-inflated greenhouses (Southern Ontario, Zone 5b). Tomatoes decline in profitability as the light decreases, whereas winter greens aren't affected nearly as much. Cutting the tomatoes out earlier could give you more time to establish profitable winter greens crops that would keep the revenue stream more consistent across the year.
Amazing stuff you're doing!
Thanks for sharing. Will try out different crops
.......I've been to Calgary and I know those winters with plenty bright sunshine but extremely cold and very dry . In Eyre peninsula here in the antipodies down under there are greenhouses designed for evaporation/distillation of seawater and cooling making use of prevailing winds for evaporative cooling. Tomatoes is the main cash crop .The land is dirt cheap and nothing else much grows if not for the greenhouse setups . It's been introduced into Somalia also , they had some famines last fee years so this system is a big help for them . In southeast Spain it's almost nothing but these greenhouses everywhere . Strawberries is another favoured cash crop cos strawberries are in heaps of nice things . On a smaller scale folk can experiment with transparent forklift wrap rolls of that clear polyethylene plastic film wound around a big framework ,, be mindful of wind strength,, .On channel of odvoko he shows what he constructed this method .
I wonder how well
-- 55 gallon barrels filled with water.... BUT....buried under the growing beds.
Would do for your setup.
Its great heat storage method
Dig out one bed at a time..
Install the water barrels put the soil back and use as before.
If you can, add tubing to circulate from the top of the greenhouse through the barrels during the summer.
Heat exchanger style, (not mixing the barrel water with the circulation water)
Don't circulate during winter.
Your free summer temperatures/btu's will be saved for later use.
It would be awesome to see how it works so far north.
Thanks again for posting these videos. I I wonder if you would be willing to give us a ballpark cost of this type greenhouse ? I appreciate you taking the time to make these videos hopefully it will help someone else be successful
a 80m long greenhouse costs about $100k CAD, incliding all the parts, shipping to Alberta and tax
@@dongjianyi2492 thanks for the info!
@@dongjianyi2492 Thank you for the very useful information. Some great videos in the future might be a time lapse video of the construction of one of these greenhouses and / or an explanation as to how much labor and skill goes into assembling all the parts that come from China. It would also be interesting to know if smaller greenhouses are available. For example perhaps a 5000 sf greenhouse that requires half of the steel supports. Loving your videos. Keep up the fantastic work! :-)
@@d.k.3316 Will do more videos on construction. A 5000sqft greenhouse is feasible.
Would you be willing to share with us where you purchase this style of greenhouse and where it is shipped from? Does this cost also include installation?
Great stuff man! How much did a 100m greenhouse cost?
GREAT video! A few quick questions:
1. What is your current USDA Hardiness Zone, and what is the same question for inside the greenhouse?
2. Can you go into some details on the thermal blanket please? What kind of material is it, and how is it deployed? What kind of tracks is it on?
3. The "top layer" of the greenhouse looks like it is loose and flapping in the wind. Is this correct, or is this the camera playing tricks on the viewer?
1. I am at zone 3b. Not sure what it is in the greenhouse. It is warm inside but still has very little sunlight in winter.
2.The insulated blankets are made of polyester fabric. It is rolled up and down by an electric motor.
3.The top layer is not too loose. But the plastic does expand as I have been using it for 2.5 years. Better to tighten it again. But currently it is not too bad.
@@dongjianyi2492 thank you!! Would you mind doing a video of the system that winds/unwinds the thermal blanket? I am extremely interested in understanding the intracacies on how this works
Being on low budget - how do you deal with bacteria in soil and illnesses hitting your crops? Industrially the grow medium/soil would need to be replaced every so often. Thanks for your videos!
as far as heating a greenhouse for commercial vegetables goes, it would be great to have access to waste heat from energy intensive industries, but barring access to that, going passive is probably the best way to go.
Where do you buy seeds of tomatoes and what are the criteria to buy them.
What are you favorite plants 🪴👀🤔
Is there any problem with excess humidity / condensation at night. How do you get the humidity out ? Amazing greenhouse by the way ! That's brilliant
I vent by opening windows
Hello Dong. Amazing work, I'm very inspired. I'm wondering, what do the temps get like in the summer? Are you able to vent it well?
Yes. I can open the top and roll up the poly on the bottom. I use shading cloth in summer. That's enough for me
This is amazing. I had no idea this was possible. Very interesting.Subbed! Good luck with your endeavors.
This is wonderful to see, and very pleased to see your success growing in such difficult conditions. Do you have any concerns for high winds with this design?
Double wall polycarbonate panel greenhouses don't loose heat like plastic sheet ones but are more expensive per panel to build, worth the money in the long run though because of the R value.
I would love to do a simulation of this type of greenhouse, do spectral optimization of the foil to maximise light coming in, squeeze the last few percent of performance out of this design. Maybe if one day vacuum panels become cheaper you can have even less temperature loss at night. Inspiring video.
Sounds great!
Simple Solution to Income .
1. Simply plant high THC Marijuana in the Greenhouse at one end . The profits alone from MJ will pay the Bills for the entire year with the Greenhouse and you can select grow other crops at leisure while you get 3 MJ Crops every year from it .
Fantastic!
I have a high tunnel in Homer Alaska and I started my peppers and tomatoes this week. I normally have them started Feb. 1. I will plant them out into the big greenhouse in April.
I did not see any air circulation fans. Is air moisture and condensation a problem for you?
That's so cool. Do you heat the big greenhouse in April? I vent by opening the top windows and rolling up the poly films on the bottom.
Hello, Where do I find the thermal blankets that you use? Thank you
How much did it cost to build this greenhouse?
Hello from just south of you in MT! Wondering how you deal with cooling in the summer. I love this concept for a greenhouse, but I can imagine it would get really hot in there really fast without some pretty serious ventilation. My greenhouse will easily get to 55°C if I'm not careful.
I open the tops and roll up the poly films on the bottom to vent. I also use shadding cloth
@@dongjianyi2492 Very interesting. Thanks for your response! I've since watched your webinar video and you answered the question there.
It's so cool to see this design. I've been dreaming about almost this exact design for a couple years, but I'd never seen it before. Only difference is I'm not on the flat land, so I want to build it into a hillside.
👍👍
Looking forward to your journey!
