If you want more videos on greenhouse growing, comment topics below and we'll get them going this Spring!
Growing desert fruit trees or Growing plants in big fish tanks fill of dirt so we can see the how far the roots grow from each plant.
Oh yes please... A frames. I'm in the process of building some green houses with the addition of a moat around them so the snow load that gets too huge starts compressing the walls will have somewhere else to flow...will send you pics upon completion. Haven't seen anyone else doing that yet. Know it's what I need in this alpine altitude.
Love your collaboration. The only issue is Cris is colder climate than I am and your way warmer. Might need to bring on 3rd in happy middle.
Yes especially if you find any permaculture greenhouses or conservatories set up for long term growth. Doesn't matter if its for food production or just for exotic warm plants. I love greenhouses.
She is so smart! Thanks for having her on your channel. That was helpful. I don't know what kind of greenhouse I want yet ... as I've no idea whether to stay Cali or move to PNW. lol
Thank you so much for bringing Chris onto the team and talking about gardening in cooler climates! Here in the Seattle area we can do a lot of the same things as California gardeners over the summer and fall, but I'm always a little stumped for what to do in the winter and how to extend the growing season. Thanks a bunch for the info :)

Hands down the most competent detailed and informative video I have seen on Polytunnels and greenhouses. Kevin you found a gem in Chris. This is perfect timing for me as I try and figure out the polytunnel options available.
She's incredible :)

Excited for this content! Few things that would be great to do future videos on:
-hoophouse - don't go under 6mm plastic thickness, if use pvc pipe use electric conduit for uv good, if use reg white pvc use tape so the plastic isn't right on the pvc. Shade cloth is also important to review, we use 40% shade cloth which here in Mass goes on by end of May. Drainage is also important to plan for.
Also, discuss the zone changes, for example we are in 5b, our hoophouse ends up being more closely to a zone 7. Extends our season by about 6-8 weeks on each end of the seasons.
Chris brings the perception and knowledge of a cold-weather gardener. I garden in 8b Austin, TX where we have some freezing temperatures, but nothing like Canada. I've always fantasized about a house with a Conservatory or a Victorian glasshouse, but I haven't won the lottery yet. I haven't even bought a ticket because I keep buying plants.
I think you have a better chance of winning with the plants. LOL

Random factoid I picked up over the years:
The profession of constructing and repairing custom glass windows is called _glazing,_ and that particular trade job is called _glazier._ So if you're wondering where "glazing" came from, that's probably why, early glass greenhouses probably involved a team of glaziers.
The more you know!

Right on Kevin....up here (Victoria, BC, a stone's throw from Vancouver!) greenhouses are a necessity to extend the season and get the starts ready prior to the last spring frost date. Glass was the choice for many years, but now a lot of use polycarbonate. Light, relatively unbreakable, you can cut with an exacto knife, and a higher r-value than glass! 🙂
Love to hear that!
Chris is a great asset - a wealth of info and presents it very well and very clearly.

My roommates and I built our own poly tunnel last year. It’s by no mean beautiful but it’s made out of wood we got completely out of construction dumpsters. That helped keep cost super low for us. Only had to buy a box of nails (yes we used nails), poly, and pvc for the arch. Highly suggest the diy route of you want one but don’t wanna break the bank.
Nice, that sounds interesting. Do you have any videos of it posted on your channel or any of your socials?

Chris, thanks for the excellent tutorial. Your content is comprehensive, presentation is warm and engaging, and fun to watch your enthusiasm as well as well-chosen supporting footage of sample structures.
One thing I've learned from this that wasn't mentioned... I would most definitely rig solar power to run everything electrical in my greeny/tunnel. Seems like what ever method you used to extend out your growing season, it could get pricey running a heater and fans.
Great call!
Love Chris's tutorials. She is a great addition to your channel.
Don't forget that cold frames exist, too. They may not do everything that greenhouses or polytunnels do, but they are a much smaller investment if you are looking to extend your growing season.
I have a spot that already has a wood frame. I'm hoping to use it to make one. I know a plexi source that could give me a deal on his scrap.
Planning on a cold frame video!

Thank you Kevin for including Chris. I like the insulated reflective material she has on the lower part of the greenhouses. Makes dual functional sense. Cheers Chris! :-)
I clicked on the video expecting to hear how you use and get the most out of your greenhouse. A a video on that would be really helpful. Would also be interested in specific topic videos...options for heating, for ventilating, issues for people in cold climates or warm climates, how to care for your greenhouse, how to elevate a basic polycarbonate panel greenhouse kit. Thanks and looking forward to more greenhouse videos.
We'll be doing that!
As somebody who lives in NW Montana (zone 4b) I really appreciate what Chris has brought to the team.
Kevin, where did you get this lady? Smartest move you’ve made on this channel, she’s a keeper! Chris, you’re a keeper! I’ve been a fan of this channel for a long minute now, but learning good information from the PacNorWest is great for me since I’m moving from SoCal to closer to the PNW.
Appreciate your channel. I moved away from the city to the rural lands. Building my hogan rn and clearing up 3 acres of land for farming. Youre channel had been such a great help in my researching.
Awesome video, can't wait for the next one!!! I live in Minnesota and would love a space where I could garden year round, even if it's just a potting shed with a clear roof so I can start seeds in the spring a little earlier and do a little container gardening in the winter.
I'm learning so much and intrigued about how to grow tropical plants in NJ. I'm a fan of Epic Gardening. Gardening is similar to surfing, they both study and try to predict the weather
the addition of Chris is awesome, Ive loved the channel for a while but always had to remember how different my zone is compared to Cali. She rocks
She is the best teacher! I love listening to her. Very helpful video!
Thank you! Our first greenhouse this year, we intend to keep it going year round for obvious reasons( vegetables now cost more then growing) .We purchased a double paned polycarbonate 8x16. We are so excited. We still have our beds and huglekulturs as well and there maybe no yard left doon!
I love this video I don’t know how many times I have watched it. Very informative details for garden lovers. Love it and thank you for sharing!!!
Chris is wonderful! You are a great team! Thank you. XX
I love this! I’d love to see a future video on different climates for greenhouses, or a visit to a botanical garden to discuss greenhouses with experts. My dream is to have a tropical greenhouse to grow orchids in a cold climate- and while I know it’s not your normal thing, I think it could be super interesting!
Great idea!
Great video! Im so glad you guys keep the content fresh and meaningful. Having more cold weather info is great. Thanks guys!
Wow, Chris, that’s a great investigative report on a very broad topic. Well done!
Wife’s been wanting me to do a small greenhouse instead of indoor seed starting. Guess it’s time to study- thanks Kevin. I’ll watch this one over and over.
We'll need to do some budget greenhouse reviews!
@@epicgardening yes please!!!!
@@epicgardening There are more cheaply priced greenhouses, but you need to cover how to anchor them or else they blow away. Any tips on those would be a help.
Would love to see more videos of growing crops in greenhouses ie: pest or pathogen control. Thank you for adding Chris to the team. So knowledgeable and represents us living in the Pacific Northwest. For me that's Haida Gwaii.
Thank you so much! I watched this twice! I am thinking of going to school for greenhouse tech so I am sure the knowledge I've learned will help me. I also am thinking of making a mini hoop cover for my pumpkins as they are getting way too much water with the rain.
I can't wait for the next greenhouse vid. I bought one of those mini ones but I'm not quite sure on HOW to properly use it... Especially in March when nights can dip below freezing but the day can be 10-15 Celcius.
Love this video and looking forward to a series on green houses and polytunnels!
I would love to see a video about greenhouse growing specifically in hot, arid areas! I live in Southern California zone 9b where our summer heat waves can hit 119° for almost a week at a time. I'm moving at the end of the month and I'd love to have a greenhouse in my new backyard but I'll definitely need some tips on heat management. Thank you so much!
Love this video! Can’t wait to have space for something like a greenhouse. One attached to a house would be amazing. Cheers to a successful season everyone!
Rewatching this video because I love Chris' delivery and information and the fact that she's also Canadian! Would love to see a similar collab with Gardening in Canada -- she is a soil scientist based in Saskatchewan and is also super knowledgeable, but also has the very different take of being a Canadian prairie gardener (Vancouver has very mild temps -- Saskatchewan has anywhere from 5-9 months of winter per year plus fairly hot summer temps -- lots of extremes that are pose a unique gardening challenge!
2nd this, Gardening in Canada is a fantastic channel!
Loved this video and cant wait to see the next one with Chris!
Really informative! I never knew this much about greenhouses.
I adored listening to Chris! Brilliant video, thank you so much.
Perfect timing
I’m wanting hubby to build me an enclosed area Florida sun in the NW area can be a killer and winter is no better. Need to determine what I need revising this video with hubby
Again thanks
This was a great concise overview that hit all the major topics involved. 👍 👍
This is excellently comprehensive. Very well done.
I learnt so much as I am in process of setting up a poly tunnel ! 🙏🏼🙏🏼
Oh Wow, beautiful Large Green house video,; I make Mini Green houses for $5, so far no need for a large green house, but one never knows and always good to learn and know. 🍅🍉🍓🌽🥕🥦
$5!
More videos please. What are optimal temperatures in the greenhouse? My 6x8' polycarbonate gets over 100 degrees when the sun is out.
I think mine would too. We had snow last night, but only half a sunny day today melted most of it!
Great info. Please continue to post more on green houses and poly tunnels. Many thanks.
I have Two small polytunnels with free ventilation last summer. There was a storm and the tunnels went flying :( this year I have enforced the tunnels (we have a lot of stormy weather after every period of warm weather. If it goes above 28C for more than a few days there WILL be a storm). A lot of folks have issues with "flying" polytunnels where at least the sheet rips off. Durability therefore is lower in zones with extreme weather. That's why im saving up for a polycarbonate Greenhouse. They last wayyy longer in this climate.
Storm proofing an enclosed structure may be ventilating it on the lee (downwind) side. It's common practice in tropical climates to weather high wind conditions. I believe it involves physics and static pressure head. Open it there It's worth a try.
Thanks so much for this! Looking for the next greenhouse video! 😀
Such a great video, you answered 95 % of my question.👍
Just found you and just in time, in a few weeks I’ll be working on a garden in my friends small greenhouse to get going on some fresh veggies for them
Great video! Would like to see more on greenhouses and indoor growing!
Thank you!
Very informative. Thanks Kevin 👏.
Very helpful n excellent idea incorporating the garden as apart of the home 👩🌾
This will be a wonderful series. I’m in central Texas, zone 8B, and am researching a possible greenhouse. I have plenty of space but it’ll most likely be sitting unused during our very hot summers. We don’t have harsh winters here but last year had a very frigid period for us, and a brief one this winter so I’m having to rethink having one without power for heating, even if it isn’t used much. My seed starting would be easier if I had the dedicated space. Looking forward to the next installment!
Austin, TX 8b usually has moderate winter temperatures, but the awful experience of February 2021 took down the TX electrical grid. There would be an issue with heating the greenhouse or polytunnel when the temperature got down to 9 F.Generator would be expensive.
We have a hoop house same zone. Heat is a struggle. I can get it to 10 degrees warmer than outside which doest work in the middle of summer. Make sure you buy a large exhaust fan. I didn't have the hoophouse over the winter but I am going to try a crockpot filled with water and put a piece of plastic lower so it doesn't have such a large area to keep warm. . I've also seen people use a fish tank heater in a bucket for heat
I finally made my tunnel came out pretty good been having a lot of fun this year now it’s time to learn what to grow and times
I get a lot of cold humidity ( ocean fog ) in the summer ( June/ July ) and would like a video on how I can use my greenhouse during this time to grow tomatoes, squash, cucumbers etc. because they can get mildew if I grow them in the garden. My greenhouse stays warm ( 80 degrees +) and dry during these months and I can grow a second round of veg outside in August- November when the fog is gone. I’m a block away from the ocean and the fog can get very thick in summer when the valleys get hot.
Loved this, very timely for me!
I worked for 5 years in a greenhouse and nursery that used polytunnels almost exclusively. One problem we ran into occasionally is that Quonset tunnels can't handle snowload. they collapse from really wet and heavy snow. We also used to put 2 layers on and use a blower to inflate the walls and help with insulation.
This was so helpful_ looking forward to the next greenhouse video
Excellent overview and comparison! Thank you!
...I want to build a green house out of that invisibility shield stuff. I saw a video about it on TH-cam...
Still, I was looking to build cold box covers for winter gardening, and i think I might be able to make use of polycarbonate! Even the info on the plastic sheeting is useful, as i'm more likely to go with a cheaper option XD; I'm stubborn and will not be hindered from producing!
Still, we were talking about putting up a greenhouse in our driveway, as my husband hates backing on and off the major highway.
Love Chris' segments!
Perfect timing!! Thanks!
My small greenhouse works for seedlings in spring, looking to also grow some shade veggies in there, all year.
Thank you so much! My husband has just started putting together the materials for my greenhouse and I am so excited!!!! Blessings! This helped a lot!🙏🕊🤍🕊🤍🕊
A video on end to end cost from starting to envision a greenhouse like this to starting to have veggies and fruits would be great.
Thanks for adding the Canadian component. I bought a poly tunnel in the fall and the more research I do the more buyers remorse I have. This video was super information and wish I had seen it first. I am in 3b zone so some kind of structure is important.
I'm on the east coast of Canada and am considering purchasing a poly tunnel. I'd be interested to know what your concerns are. Thank you.
@@alpinereid5265 First its cold up there,(i know , obvious ) second greenhouse orientation will make or break that project, third you will need a insulated north wall. fourth you will need some way of supplemental heat, geo battery ,solar mass, propane. but something.
@@alpinereid5265 just for what I want to do I think that a polycarbonate would have been better. Plus I think I spent too much money on it. It is not quite big enough for inground and haven’t figured out how I can do irrigation if I use pots (as I am sometimes away for a week at a time. And in addition, as per what Chris was saying that a poly tunnel doesn’t necessarily help if there is frost ( she has suggested blanket over or having a second layer and blowing up in between. So I wanted to use to put out seedlings to make things easier for hardening off.
So much great information!! Thank you so much.
This was very helpful. Thank you!
Thank you. Very useful, clear explanations.
I love this. It was SO helpful!
I live with the Chinook so definitely would prefer a greenhouse. Someone's trampoline or chair might end up in my garden during the windiest days 😄
I really like how Chris presents her piles of knowledge on things. Very articulate. Thanks for this great video guys.
Great info Kevin & Chris! 👍
Thanks for this video...very helpful and informative for a newby like me
Would love to see a video on a polycarbonate structure that comes highly recommended or that is currently being used by someone you know! Thanks for all of the great information!😊🌱🌷
Very helpful video, thanks for sharing
Such great content! Top notch! Thanks!
What a great video. Informative and entertaining.
Lots of good info. Would be interested in her second one.
Great video Chris 😊thank you
Great video! Very informative, thank you. 💚🌱
Absolutely loved this. I realize there is no way to cover this collectively - but my issue is my city and it's restrictions for backyard structures, even for a simple shed. The rules are Cuh-RAZY.
Wow! I thought my municipality was bad, as depending on where you live, they have a maximum building density per your area of land. There is a lot of resentment towards the municipality too, because while the building density of the properties owned by the average home owner is only 30% in my area, just down the street is a commercial property that will be a hotel and their building density is 60%. Really feels like it is kinda corrupt; one rule for one and another for the super rich property developers.
Would love a video for arid or semi arid growers where it’s hot most of the year (100F+) and insects almost always present!
I would love to hear about pollination in an enclosed environment. I built a small tunnel last year and had pepper plants in there. (I get super hot sun in Sonoma). They didn’t blossom. I dug them up and planted them outside in the garden and they thrived. Do certain plant grow better in an enclosed space?
So helpful, many thanks
Thank you
Very insightful
Awesome video. Super great info.
Such an informative and fantastic video. Thank you! My one question is how in the world can I sustain a year round microgreen farm inside either a greenhouse or polytunnel in a low desert environment where summers rise up to 120F?? Any advice would help!
Great info, thank you!
I really enjoyed this video as I am researching Greenhouses now. I would like to find a greenhouse kit that fits my needs. I want something sturdy, but can’t afford anything too expensive. I would appreciate any information you would have on the subject.
ME TODAY-
Me: looking into buying a greenhouse
Also me: how the heck do I take care of a greenhouse?

I put up a poly tunnel for less than 100 bucks 4 years ago over 2 raised beds door on north an poly door with construction zippers 2 layers plastic an grow veggies in winter was 31 below one year for cooling us a 100 watt solar panel an DC 6 or 8 inch fan now don't heat but added a small DC heater to solar panel so you get cooling as it heats up an extra heat
great video
thanks for sharing
Thank you for the highly informative video! I've dabbled in the low end of small greenhouses, and I find they vary enormously in internal temperature, and are too small to have much thermal mass, so the temperature swings wildly between day and night. I have limited space, but could benefit a lot from protection from short-term freezes in late fall and early spring. The small greenhouses seem only usable for a few nights here or there. Are there good options for, say, an 6'x8' greenhouse? I don't have enough space in unforested areas for anything larger than that.
Thanks for the information
What a great video!
Thank you so much. I really wanna create a mini greenhouse
Thank you. Very informative. 😁👍🏻
I’m in Cyprus, in a Mediterranean climate so (esp in the summer,) my greenhouse would most likely end up as a shade-house. Yes, it would extend my season once winter arrives, but an actual greenhouse would only extend the season by about 3 months.
We have a Mediterranean climate down in South Australia. I’m concerned about the heat in summer at 45C +. But, you’re right, I’d have to turn it into a shade house then take off the shading for winter. Cheers.
