For your heated seed flats , on top of your heat mat, put another flat on top full of sand. Then the actual seed starting flat. It will act as a heat " battery" and keep a more even temperature , with the advantage of holding heat for a period of time should the power happen to go out . When i was in college for my hort degree this is how the campus Greenhouse was operated. You can also add a timed mist system for seed starting.
If you put your heat mats on a piece of insulation it will be way more efficient. Half inch polyiso with the tinfoil on it works really well. Putting clear domes over your flats will complete the system to keep your warm weather seedlings happy in the cool weather.
I finally found my humidity domes so I've since added those onto my trays. Great tip to add insulation under the heat mats- I'll have to try that out. Thank you!
That's a great idea. Do you mean regular house/wall insulation?
@@clb50 Yes, house insulation. Styrofoam will work, but polyiso with the foil, vapor/radiant barrier is probably the best. I'm talking about sheets of hard material that are 1/2" or 3/4" thick.
Good timing on this video. We're planning on getting a bigger greenhouse and this hf 10x12 is definitely a consideration for our needs and its cost. We have a 6 yr old similar one 6x8 . How tall are the short walls on the 10x12? Look like over 6ft for sure
Quel beau travail! Vraiment très intéressant puisque j’ai aussi une serre mais 6 x 8´ et au Québec! J’ouvre ma serre à la fin d’avril et moi aussi je l’utilise vraiment plus au printemps. Par contre, j’y installe une toile d’ombrage pour l’été et mes fleurs aiment. J’en profite pour cultiver un plant de tomates! Oui, les dômes aident vraiment à la perte de chaleur car même si les racines sont au chaud, la plante n’aime pas le froid sur ses feuilles. Il y a le ventilateur aussi qui aide à maintenir une bonne température et aussi un bon renouvellement de l’air. J’ai installé aussi un petit cylindre à ma fenêtre permettant l’ouverture automatique. Bien graduée, ça pourrait être aidant puisque le fenêtre s’ouvre lorsqu’il fait trop chaud. J’ai mis du silicone à l’intérieur et à l’e terreur le long des panneaux. Attention à la porte coulissante car j’ai dû changer le mécanisme. Mais c’est après 25 ans! Hi, hi! J’ai changé les panneaux trois fois parce qu’ils avaient jaunis. La structure est encore très bonne donc je l’ai conservée au lieu de faire l’achat d’une nouvelle serre! Mon panneau électrique me permet d’avoir un thermostat qui maintient la chaleur adéquate dans ma serre. Et je garde plusieurs arrosoirs d’eau qui, aide à conserver la chaleur aussi. Des pierre aussi au sol aident. J’ai aussi installer des led afin de mieux compléter les heures d’éclairage de mes semis! Je ne laisse aucun pot et terreau à l’intérieur afin de conserver l’espace libre pour mes semis. J’ai aussi 3 thermomètres. Le plus stable est celui qui garde la température qui a eu durant la nuit: la plus froid ou la plus chaude. C’est très instructif! Je songe peut-être à utiliser les plastiques à bulles comme isolant. Mais je n’en suis pas certaine! C’est un beau projet très agréable! Bonne continuation!
I've owned my 10x12 HF for over 10 years now. It was anchored down to an existing concrete pad to prevent it blowing away. Over time, the base that is only made of metal, not aluminum, rusts away, and the poly panels become brittle and break. They will also fade and become a cloudy yellow, but it served its purpose for about 8 years before I had to put money back into it. It's generally too hot to use in the summer in my zone 5b/6a, but works fine the rest of the year. If the sun is creating too much heat inside (spring/fall), I pull the shade cloth that is suspended inside on vinyl-coated clothesline wire to reduce the temp. along with venting. Being heated with a blue flame ventless heater in the winter melts the snow on top and prevents heavy snow loads from crushing it. Have fun with yours.
I'll have to try a shade cloth this year to help with the heat issue. I eventually would like to replace this kit with a better temperature controlled greenhouse, but I do really love it for the joy it brings me now 😊 I'm glad to hear yours lasted as long as it did before needing some TLC!
That's cool. I like that a high tunel can be easily assembled and disassembled and might actually be easier to double wall, and cheaper! 👍
How easy is it to double wall? We are going to build a cattle panel hoop house with ridge beams etx for our snow loads.

Thanks for watching! Yes, a high tunnel is definitely cheaper when considering how much space you get. I'd love to get one in the future. A high tunnel plus a heated greenhouse to start seeds in is the best of both worlds!
thanks for the tip about the Facebook Group!
It's been a great inspiration for me! Thanks for watching and happy gardening
You could use some caulking along the gaps to keep that foam in place and that should seal up any air gaps.
Thanks for the advice! I think I may have meant to do this last winter and never got around to it. I'll have to pick up some caulk the next time I'm at the store. Thanks for watching!
My late husband & I bought & constructed one of the 6x8 HF greenhouses. I love it.
They're great starter greenhouse if reinforced properly! I love mine too 😊 Good luck to you this growing season!
I really appreciate this content. Your perspective is meeting me where I need to be stretched in my story of being a gardener. You just experienced exactly what I have pondered. Thank you for sharing with me. Your presentation is relatable and professional.
Heat mats will only give you a 10 degree boost , they are working perfectly as you mentioned they are always showing a 10 degree difference compared to the air temp. thanks for the tour!
Thanks for watching! I love these heat mats- highly recommend!
They make a regulator for those vent windows in the ceiling it opens them automatically and closes them depending on the temperature
Put large black barrels filled with water under your grow-shelves as thermal mass to hold heat into the night.
Great tip! I want to do this once I get my floor leveled out. Thanks for watching and happy gardening
I just wanted to say this was a good video. I do a lot of marketing for companies and you seem like a natural in front of the camera. I subscribed to your channel and wish you all the luck on your new venture
Thank you!
Nice work!!!!
Appreciate the ideas & source material very much
LOVE THIS VIDEO! Thanks for all the tips! You did a GREAT job ❤
Shade cloths are really great. There are different degrees of cloths, 10%, 20% etc I used a medium shade cloth over my green peppers last year and my crop lasted 4 weeks longer than my neighbors. I processed a lot of green peppers.
Nice job. A greenhouse is on our list of projects to do. I will check these out.
Thanks for watching and good luck to you!
Great video! You are really knowledgeable. Thanks for sharing!
Thank you for watching! Happy gardening
Installing a shade cloth would help with the high summer temps.
Thanks for the tip! I was thinking abiut giving shade cloth a try this year. I'll have to revisit a little later in the year when it warms up. Happy gardening!
Nice to see a local, I am in Mechanicsville.
Very cool! We're practically neighbors in New Kent. Happy gardening 😊
I have that same greenhouse and I attached the bottom to 4 - 4x4 post.
I had considered drilling lag screws through the base and into the 4x4s I have in each of the corners but ultimately decided against it. What did you use to attach them?
Real nice video, lots of helpful information. I’ve been considering the HF greenhouse. Two thoughts to share... 1) periodically keep a fan on low to circulate the air to even out temps in the GH and 2) consider some black tarp, cloth or plastic on the opposite wall of the GH for solar heat gain in the early part of the year when temps are lower. Your heater will not work as much and the solar gain works even when it’s cloudy. Happy gardening.
Great tips, thank you! I think a black tarp (or something similar) would be helpful on the western side of the greenhouse. There are trees lined up along that wall so I don't get much sun from that direction anyways. I do have a black tarp lining the ground to help with heating and weed supression. Thank you for watching!
I would also stack haybales along north side, all the way up to eaves, for in winter.
Nice set up, my husband built me a cattle panel greenhouse, I also got a small walk in one. Eyeballing the HF ones now too. lol I'm so excited for Spring!
I love my greenhouse for the purpose it serves but I think the cattle panel greenhouses may be able to conserve heat a little better because of the limited headspace. I'm eyeballing tunnels now for year-round production! Thanks for watching!
Nice info, thanks!
Thanks for watching!
Like the greenhouse. We just built ours out of old windows/doors. But the price on yours is pretty good. Even with using some recycled materials, ours was much more than that.
Thanks for watching! I eventually want to build a sturdier, better insulated greenhouse but I think this is a great option if you're on a budget. Most of the wood we used I already had lying around so the whole project ended up costing me about $1,500.
Good job on your greenhouse build. I have a similar smaller one on the way for my cacti. I will use the tech screws as well. I purchased concrete pavers for the floor. I think I will drill into these with a masonry drill bit, and screw the greenhouse down to the floor. Good idea on sealing up the ends of the coreflute panels to stop dirt. Thanks.
thanks for sharing... some good ideas and tips here. i recently finished assembling mine (same model) and am thinking about enhancements and hardening.
Thanks for watching! Good luck to you
Very detailed tour, good job. I sure you already know about this, but my mom had some kind of black mesh cloth that she had hung up in the ceiling of her greenhouse & it really helped with keeping the heat down in the summer. I can't have a visible greenhouse in my neighborhood, because I have a snobby HOA, so I have grow lights, heat mats & a radiator heater in my garage that I move my delicate plant into during the cold months. Other than a slight problem with fugus gnats, it works really well. Good luck
I've been there too prior to getting this greenhouse! You work with what you've got. I've looked at shade cloths before but haven't invested in one. I think I may end up trying it out this year and seeing how it goes because it does get hot enough in my greenhouse to damage plants. Great tip! Thanks for watching and good luck to you!
Good idea for the panel reinforcement self tappers. Id add a fender washer for more holding power.
I have had this greenhouse and it is pretty beat up after 3 years.
We have HF in KERRVILLE, TX. Hill Country. Good Video 💚💚💚💚 💚💚💚💚💚💚

Go buy some white lithium, grease, and apply it along the rail where the wheels roll. Make sure it has a low temperature rating for winter, apply it not too thick, so it doesn’t come up. That will make a big difference for your doors. You will have to put a little on once or twice a year but you’ll be very happy with the results.
Nice job building what I do is put a sheet of clear plastic over my trays making a tent inside green house then I use an electric oil filled room heater below and turn on low when temperature goes to 32 works great during sunny days tent temperature is 5 to ten degree warmer than green house the plastic over trays keeps moisture on top of cells and I don’t have to water half as much thanks for video
Great tip! I found my humidity domes which create a similar effect. Plastic will work just as good though! Happy gardening
If I were you I would have an electrician come out and run formal conduit to the greenhouse for power, the heater/mats/lights are quite a lot to draw thru an extension cord. That heater alone pulls 1500 watts... :)
Extremely true, That’s a fire waiting to happen!!
Best advice I've seen so far. I've seen 12/3 HD extension cords melt from space heater loads, scary stuff. Hopefully they at least touch the cord now and then to see if it is radiating any warmth from the cord itself.
Thanks for watching and for the advice. I plan to eventually build a bigger/ nicer greenhouse and the future and would like the help of an electrical for that project. The extension cord I purchased for this greenhouse is a 12g 125v cord that has a higher max wattage than most typical extension cords so the heater plus the heat mats are still within my wattage restrictions! But yes, I agree that an electricians work for heavy use is the best route to go.
My heater and mats are within the wattage restrictions of this particular cord. Thanks for watching!
Thanks for the advice and for watching! That does sound scary. My heater and mats are within the wattage restrictions for this particular cord.
I don't know if you get a lot of wind but we had a tarp type building to house our tractor, etc. and it ended up blowing over our barn roof and ended up in our pasture 50 feet away. Thankfully it didn't damage our solar panels on our barn roof!
Oh wow, that's scary! I had thought about it blowing away and that was the ultimate deciding factor for building a complete interior frame for our greenhouse. Sorry that happened to you. I hope you were able to rebuild or find an alternative option.
😊👍
Hello from my homestead in northwest Florida zone 8b. This was such a nice informative enjoyable video. I hope you are doing well, how did the greenhouse do for you this February 2024?
Very nice video and great ideas! We just completed assembling ours. What is the height of your work table? Oh and I just subscribed to your channel and joined the FB group! From Minnesota!Thanks!
Try putting a silicone sealant around each side of your panels. I find that Mastic or a roof and gutter type are the best. I hope this helps...
Nice video, good suggestions & tips. I’m installing a greenhouse from a different company this spring. My specific question is “What weed block fabric did you use for the floor?”.
Thanks for watching! It's just a black heavy duty 10x12 tarp. I poked a few holes in my low spots so that water can drain through if it gets wet. Good luck with your greenhouse build!
That’s a lot of modifications! The comments on that model agree that wind resistance is very weak. A good wind can create 15-20 pounds of force per SF applied sideways!
Thanks for watching! I think it's a great starter greenhouse but I do think the modifications are necessary, especially due to the max winds as you mentioned.
You’re right; “thermal management” is missing for the cooler months. Adding things like black 55 gallon barrels eats up a lot of floor space in a small greenhouse
I have considered using black plastic storage bins with water underneath the shelves, but I have not leveled out the floor yet. I may consider adding a few in the future but I do value the floor space to store other supplies. Thanks for watching!
Not if you line them up on the north wall and use the top as a big shelf to hold starting beds
I have the exact same one and I'm in zone 6. We got a heavy wet snow and it totally crushed the roof. We did frame up the sides and they help up but we didn't frame the roof. Our mistake. But I do think if we had it would have been fine but the metal is so cheap that the doors are crap. Hope your does well.
I'm sorry that happened to you- I hate seeing people post about their greenhouses blowing away or falling in and all their plants are lost. I love mine for the purpose it serves me but I do eventually want to build a nicer and better temperature controlled greenhouse in the future. I think the HF kits are great beginner kits for a budget, but I do think reinforcing them is crucial. Luckily, central VA doesn't get a lot of heavy snow so I haven't had to deal with that before. I hope you were able to rebuild or find an alternative option!
Shade cloth on the roof will help with the amount of heat in the greenhouse during the summer.
Nice video. I am just setting up my first greenhouse and trying to figure out how to heat it. Your heater lights are flashing, but our eyes can't see it. Iphones capture video at 24fps so it makes it look like they are flashing in a video.
Can you use silicone caulk when installing panels
We bought the same one- do you have trouble keeping your doors on? Ours pop off randomly at the top rollers😢
Mind wound up on the Fence across a 40 fot yard the 2nd day after I put it together, severely mangled & unusable, fasten it down.. just ask me how I now
I'm sorry that happened to you...it's devastating when you put all your plants in there and they end up crushed. I think they're a good starter kits for a tigher budget but they definitely need to be reinforced. I hope you were able to rebuild or find an alternative greenhouse.
If my math is correct between those heating pads and heater you are running close to 2,000watts at 110v that’s about 18 amps and that extension cord looks like a normal one which are usually only rated for 15 amps. I would look into this and check my assumptions, don’t want to cause a fire or something.
How would this handle snow loads?
We do not get heavy snow in central VA where I live, so I have not had to deal with this. If you get a lot of snow I would suggest building trusses into your interior supports to help manage the weight. The polycarbonate panels and aluminum structure are not very strong by themselves. Good luck to you!
What are you using for your soil?
I just picked up some Miracle Grow seed starting mix for the mini blocks. For the 2" soil blocks I mixed some old potting mix I had with homemade compost and perlite. I like Coast of Maine and Fox Farms potting mix that I've used previously if you're looking for organic options. When I run out of my current mix, I will probably get either of those.
@@fewacrefarm Thank You so much for your time.
Mine lasted, 97 days before the second 50 mph winds crushed it to the ground
There's no way this thing can withstand accumulations of snow in the winter. I think people that live in the north will have roof panels caving in from the weight of the snow. Might want to overlay a large piece of plastic or tarp over the roof for the winter months in the north.
Fortunately we don't get a lot of snow in Central VA, so I haven't had to worry about this issue. I've seen where people have also framed out trusses on the interior of these kits to support the roof and I think that could work well in more northern areas. A tarp on the exterior is a good idea too!
@@fewacrefarm actually a tarp would prevent the GH from heating up and shedding snow naturally. We used the panels from a friend’s GH like this that blew over and created a lean-to on the garden shed.
Debating. We used parts from a friend’s blown over GH from HF. We built a lean-to GH against the garden shed. It has been terrific over the years, but we will be redoing it this year. The panels weren’t the best quality or condition to start and are quite clouded. After hearing all the modifications of this particular GH I’ve decided to just get some quality panels and redo what I have. I’m installing a heat sink in the floor and repurposing some refrigeration building panels around base. The north wall is the shed and will utilize that as well for heat. In the summer I put 50% shade cloth on top. However I just read to not let it rub on polycarbonate panels and will need to put a few slats across to prevent.
I love our small footprint, but will add a couple of feet to keep it easy to heat.
I’ve noticed on many GH have open vents, but I would add screens and an operable screen door to keep out bugs. I use mine for seedlings and in fall to dry onions.
Well after I recycled the bulk of the aluminum frame I got less than 30.00 minus the door frames and a few pieces of frame I found in the snow..
But it turned into a 3500 insurance claim
Reinvest in 450. In rough sawn lumber
Complete rebuilding in a day purchased real polycarbonate panels for the roof both sides, and steel wall to the north I lined the back west wall with the old panels the south wall and front other than door, lined the inside of the south wall to double layer.
I'm going to Rockwool the north wall and put black steel over that.
I had already installed 4.5" of insulation for the floor covered with #2 stone prior to the storm. I'm ready for pavers and water & electric. I'm going to use the door panels for the new door & use the rest of the smaller ones for the inside of the front.
I cut 7" wide strips out of panels to cover the joints and bent over them to make outside corners for the roof and 4 corners.
So far so good nothing blown away yet since September and still have to build the tables and grid the east inside wall I'm going to use polycarbonate panels for that then it's layered inside & out no blower needed.
What you keep calling elbows are referred to as braces .
useless in high winds this kit
Yes, I highly recommend reinforcing it. It's a good option for people on a budget though for a starter greenhouse. Thanks for watching!
Please invest in a microphone.
I plan on it! I'm new to vlogging so I'm still shopping around. Do you have one you suggest?
@@fewacrefarm Rode is a good brand to start off your research.
