Install a misting system , that will take care of the heat. I’m in Texas and most of the time , we have temperatures above 80, but since I installed the misting system that problem went away ..
The best part of my greenhouse is when it’s cold and windy outside in the daytime, I can go inside and warm up, and that’s about it.
I have a Grandio greenhouse similar to yours. I’m a Master Gardener with my county and what I tell my students who want a greenhouse: you won’t own a greenhouse, it will own you!” I have gone through the very same journey of discovery on how to manage the temperature swings. I am tied to it in ways I didn’t anticipate. I’m checking the temps, I’m opening the doors, I’m closing the doors, I’m checking that plants have not dried out, etc.... I live at. 8,000 ft elevation at the foot of 14,000 ft. peaks in Colorado. We have a lot of wind that sweeps down the valley. We put, same as you, a solid timber foundation secured by rebar stakes driven deep into the ground. We used tie down straps to hold it to the foundation. It has withstood 70 mph wind gusts. Like you, we wanted it to be passive solar but learned the black barrels were not enough to warm it this spring. We had 6” of snow a few days ago & our low temps have been in the upper 30’s. So we just got a diesel powered heater that runs off a battery . Looking to hook it up to solar soon. Then our afternoon temps have been in the 90’s. So we got a aluminized shade cloth (like commercial greenhouses use) and that lowered the temps about 10 degrees. We have 3 auto windows in the roof and a louvered window like yours. So, like I said, “the greenhouse owns you!”
MR. SANDY: I have a greenhouse in Pennsylvania. I appreciate hearing how you do things in your zone. The barrels of water help greatly. I've found using old carpet as weed block is free and more effective than weed guard. It also let's the water through. You can often find old rolls along the street on garbage day. Try it! P.s. Use caution and wear sturdy leather gloves. Old nails and staples. Use a new utility blade to cut to the width you need.
Really helpful for a prospective buyer, considered the same item. It's not really bad mouthing, just assessing and managing expectations, they also make the versions with various glass panels. For me it makes more sense to save/wait a season, getting the wrong item could put people off entirely.
i live in the frozen north......i just put greenhouse plastic over top in winter that extra layer makes a diff in -20......at night i but very hot water bottles in there to thro off some heat .....then use it to water the next day =-)
Gardener from Maple Hill, NC here. Thank you for this video. I have a cheap, all- plastic greenhouse and I know I will need to upgrade in a few years. The more I hear about these prefab greenhouses, the more I'm convinced to take the time to make one myself. Looks like I can build a more secure one that is larger for the same price of a premade kit.
I have a 8x8 palram snap and grow. It is two yrs old. I am 70 yrs old and put it together over 2weeks. I did 95% alone. The foundation took the longest as I had no experience with power tools except a driver. That was CRAZY! But I love my greenhouse. Mostly use it for germinating, seed saving, gardening supplies, space to work on other projects etc. I am in Indiana and this is my second year with winter planting. I do that outside under row covers to extend my season. Thank you for the information.
Good stuff
I just want to say right off the bat you are a fantastic communicator. You answered every question I have before I make a purchase like this I like the idea that you bad mouth is a little bit but you also included all the positive and that's just to me a straight-up honest review. I'm in zone 8A in South Central Alabama and I'm thinking this might be something I'm interested in because my Winters are just a little bit milder than yours. I'm going to subscribe to your channel cuz I'm interested in the future to see more about your success and failures in your area so that hopefully I don't have to go there. Like I said a great video man you're a fantastic communicator.
Thank you! I think in your area it may do well for you if you have the right expectations
Mine is specifically used for holding seedlings until after the frost date. It means I have to apply supplemental heating at night, but I only have so much room in the house.
I know the feeling that's why I worked on my footprint inside
I built a 10x6 where my old well house was. I had water and electricity already run, so it made sense. Solid foundation, and used landscape timbers to reinforce the walls. Was able to build the shelving and a sprinkler timer system. Yes, used a Solar panel to run the fans.
Yep, you right😏 I learned this with my first little plastic house. It gets hotter when it’s hot & colder when it’s cold. I find it great to start plants & for space to do so💖
I love mine in the winter. I need to find a way to decorate it in the summer
Great info and some clever tricks. I'll definitely be trying the black water bucket one next year. I used synthetic wood recycled plastic for the base of mine. I think it might last longer than wood, even if it's treated.
Just happened to come across this video because I am interested in purchasing a greenhouse. I was excited when I got my first portable greenhouse and that turned out to be a disaster in every way. This video was very informative because in my research I have discovered that greenhouses are very expensive and now I know why. Thanks for sharing your experiences. I am an experimental beginner gardener who would love to have a food forest one day soon, but until then I will not be needing a greenhouse.
Why was it a disaster in every way?! I just got a 6x4 portable one for my birthday, and now I'm thinking I shouldn't even put it up lol. I live where summers frequently are above 110°.
Have you seen the Nebraska guy who grows tropical plants in his greenhouse he took a lifetime to figure out successfully?
No I haven't
I have this Greenhouse and I have it full of what I winter over. I use a heat lamp at night and its more than enough to keep all My peppers, Geraniums and many other plants alive through the winter. I did get a Shade screen for it and If I could get another one I would in a heartbeat. Thanks for the videos.
If ran electric to it I would be comfortable growing more in the winter
I am in the Uk and my greenhouse is almost identical to yours except I have glass instead of plastic. Mine is made by a company called Halls. I tend to not grow anything in winter as it is too cold and not justified in cost to heat it. Can get seeds started earlier in propogaters and grow more tender crops in summer.
I'm thinking the 10 x 12 h vac tape at top seems and screws in panels to braces. And not have a base but dig down about a foot. Just to get my plants out about 40 to 50 days early before planting. As well I'll just buy some plastic shelves also I could run a heater and fan from an outlet on a timer.
Great tips. We just bought one of these and this was very helpful.
Think im in the wrong place for greenhouse tips, i'm in Wales where its cold, windy and rainy 90% of the time, love the accent and surroundings so much though ended up watching throughout haha
Yeah totally different here lol. Glad you liked it though🤙🤙
@@sandybottomhomestead ye love me a bit of sunshine even if it's via youtube
Devon here ,same
I am in the process of looking for a greenhouse now. I live in Zone 8b and worried it might get too hot in the summer. This video was very helpful and I am reconsidering my choice to buy one. Thank you!
I adore my greenhouse! I winter over everything and love that because I don’t have to purchase any in the spring. I have a heater in there for really cold temps.
That is awesome!
SO helpful! Thank you for sharing all your knowledge :)
Thanks for sharing this good information. We moved here 2 years ago, last year I built a wooden greenhouse for bringing from seed and it was pretty successful for a beginner. Ran out of space now and apart from the 8 external beds I'v built, now been thinking of buying one of these exact items. Thanks for the tips, if I go ahead, I now think I'll need to run power in for heating in the winter. I am in Scotland where we get a lot of rain and mild frosts in winter.
If you end up getting it I hope it works out for you.
Glass makes it much more rigid during storms.
I’m in Melbourne Australia and have one almost identical except the panels are like your roof panels all over. We spent a lot on a secure base so no strap bracing and added the automatic window hinge too. I found it got way too hot as well. We have ours close and tucked in near the house which reduces the light and heat one side and I have intentionally grown climbing plants like beans on the other side for summer shade. I use shade cloth on half also. I’ve decided to put beds in as well instead of the seedling shelving we have and grow summer tropical vegetables like okra, rosella, chilies etc. it was good to keep my tropicals in over the cool months. I have considered painting it with whatever they use on hoop houses on farms or making it more a shade house permanently. Trying the summer plants first.

I was mainly wanting a smaller greenhouse just to start plants so they get the light they need and wind doesn't damage them. I start them indoors in March, but they get too big and I have to take them outside during the day and bring them in at night which is a pain. Some get wind damaged. It's not safe to plant outside till June 1st in Ontario Canada. We can get frost in May and covering plants up and watching for frost warning is a pain. So I wanted a
small greenhouse on my deck so the plants are protected from wind and cool nights, but can get enough light and don't have to be moved twice a day. I was thinking of making a base out of one or two skids on the bottom and making a frame attached to the base. Heavy plastic or clear corrugated sheets would let in light. I water them daily as some soils dry out and don't hold the moisture.
Btw, to counter the huge increase or decrease in temperatures, it pays to put up weather proofing sheet inside the green house. That’s what they do in a professional greenhouse. The sheet comes in certain filtering of UV rays or to counter the cold and hot temperatures. It basically helps to insulate your greenhouse without sacrificing light. It goes from 15% light filtering all the way down to 75% light filtering clothes. It comes in two colors (that I have come across), black one and white one. You would often see in a professional grower greenhouse, black tarp/net structure hanging inside the greenhouse. High number of light filtering clothes are used for tropical plants that prefer semi-shade but needs warmth to thrive. You should look it up. It helps to insulate your greenhouse from extreme temperature gap. Then put up AC or heat for summer and winter. It helps to make the greenhouse larger as well to prevent it from getting very hot or very cold. Hope this helps.
I've weighed out my options. So far the greenhouse works well for what we want to grow during the winter. The next greenhouse we may add a system like that
I have a 6x8 slab in my back yard that I guess the previous owners had a shed there. It even has plumbing and electricity. Idk if it still works, but it’s there. I can’t decide if I want to put a greenhouse on the slab or not. What I really want it for is starting seeds in so I don’t have to use lights or harden off much.
My summer seeds don't start early enough in my greenhouse
@@sandybottomhomestead I’m in zone 9 so it’s practically always hot
Hope fully it works for you especially if you can raise the temp little bit
I start seedlings in Texas 8b in my current greenhouse which is an old wooden frame type with polycarbonate panels…it doesn’t hold in heat or water! But I use heat lamps and heat mats in Jan/Feb to start seeds. It works marvelously for that but nothing else except storage.
I have a small walk- in greenhouse. The wind is my issue. I'm in North Central Indiana. Great video....Thank you for all the pros and cons.
Have you tried putting wind breaks around it?
There really isn't a way that I can. I live in a mobile home park. There's only so much space....I tried placing it in different places but the wind gets it...I'm on my 3rd one. Was afraid to put it up last year....Hopefully this spring.
Try those Hurricane straps they really do help and they are cheap
@@TwistedPixie69 Our worst winds come from the west here in Ohio, so I'm planning on keeping my greenhouse on the east side.
I had a polytunnel greenhouse in NC for six years... Went through multiple high winds, near tornadoes, jail, ice, snow, and hurricanes.... Here in Ohio... The wind blows so hard and gusts up, and up, and then switches directions so much that it tears stuff away and trashes anything not tied down tight enough. Watched a for rent sign fly off the neighbors house and sliced off the top of some fancy grasses. 🤭😂🦗
I saw a guy that wrapped the lower part in bubble wrap in winter and hay bails on lower section. I just diy'd 2 bay windows into a greenhouse with solar fans etc. City so also a car alarm LOL! citrus and coffee crop. Big tub of water with fan helps. You could get 4x8 sheets of poly and double skin it add shade cloth in summer? Old school xmas lights in winter can go off invertor on timer I use em for citrus.
Yeah I could but that is way to much effort for me lol
Thanks for sharing all the deets on this! I appreciate your knowledge and opinions so much 🌱
Hi, thank you for the video.
I just watched another video about a green house. That one was twice as big and with cedar frame and much thicker polycarbonate with the top that opens. That one was $1450 or around that price. You have to of course build it yourself like this one but this was $6-7000?! I think it’s an outrageous price. I can get twice as big as the one shown here or even three times for $7000. Wow…it really pays off to shop around I think.
I liked your idea of putting a fan to suck out the hot air powered by solar. If you get a good solar panel with battery you can recharge, you can store electricity and operate your greenhouse even at night to suck out the air or even put AC on or electric operated fan.
Yeah I could do that but I'm happy knowing my limitations and growing with in the parameters.
I’m in western mass…I am super excited about this greenhouse but very grateful for your tips and advice and now a tad weary but I bought it so I gotta do it haha wish me luck! I need those hurricane straps tho!
I lived in eastern mass for a while a gardened there. You can extend the season quite a bit if you plan right
@@sandybottomhomestead yaaaa thats the hope! Up here in the Berkshires though the weather is something else. we always get frosts into june now and im sure will even get another snow fall. so i got this greenhouse to start my seeds in as I have no diret sunlight in the cabin or space for lights...my hope was it would be warmer in there than outside but from your video i believe that not to be the case anymore. I guess itll be a trail to see how this goes haha
@@brittanyp5478 I'm in the same bed (Springfield area). I just bought one (haven't arrived) and now I'm doubting the purchase LOL
My first year on my lot I planted a bunch of fall mustard, turnips, rutabagas, radishes, lettuce, bok choy, etc and here in zone 8a in Louisiana we got down to ZERO with below zero wind chill and it was below freezing for a week. Lost everything. Then it was way too cold in spring for starting normal things we usually grow. I was using my heater until May. Then by June a heat emergency and drought arrived and lasted until October. My greatest success this year was getting my baby 5 inch fig tree to survive and grow several branches. I did manage to grow okra, get one quart of Purple Hull Peas, get mint started from seed, and harvested some cucumbers and a few dozen cherry tomatoes. Various pole bean types did very little...not enough to harvest. Yard Long Asparagus pole beans showed promise though. Armenian Cucumbers did nothing. Bush green beans did nothing. I let a rabbit have them. Red Ripper Peas were a joke and I will never waste my time on those again. I may plant them in a ditch but never in my garden. Nothing will grow where they grew now. Amaranth made no seeds.
We have similar greenhouse but a couple of metres longer we string up shade cloth over the top to stop it overheating in the day time and also add a couple of black barrels of water and raised garden beds with lots of compost to help keep stablisie the tempetaure over night we grew chilli's over winter and used it to start lots of tomato trays early in winter
Sound like you have the same set up as me
Ben that's a cool set-up! Looks like you've got it dialed in very well..
Thanks man. It took some time to dial it in.
i have a heater with a thermometer for the winter and have fans for the summer. I use mind all year round.
Just wondering what grow zone you are in. I am in a zone 4b. Wondering if this green house is worth it. Thanks again
Great video! Thanks :) I've lowered my expectations lol. Do you have links to all of the stuff you mentioned (like hurricane straps)?
No I got them from palram
I was curious about those as well…
im in Georgia and have clear polycarbonate panels that are 20 years old, it still gets warm in the green house and the panels are getting cloudy.
You got good life out of them for sure
Thanks so much for this video! Does anyone know if glass panel greenhouses have the same ‘hotter in the heat’ and ‘colder in the moist cold nights’ issue?
They will be hotter if you don't vent and they will generally hold heat at night better to an extent. They are much better candidates for heaters due to heat retention properties of glass
Great vid ! I'm in my second year of using my hoop house and learning how to run it is half the art of growing in it.. they're a solar powered heat generator and you have to learn how to tame all that power... about shade cloths they seem to work better if they're not touching the surface of the plastic suspend it with a rope somehow over the top... thanks.
Yeah I know that but it is way to much work to suspend it. I just work with what I got.
I'm new to your channel and located in Massachusetts and have also purchased a polycarbonate 6x12 (aka modified cold frame). it is in an asphalt covered yard that was once an in ground pool, and yes it has been modified with flooring and I also will not heat with electric, but hopefully go through this first winter using solar or small propane heaters if possible so i can get a jump on our zone 6a area. YT suggested your videos and im glad they did so i can better gauge the use of this expensive purchase to grow what may end up in short supply in a few years🌱
I hope it works for you. WHen i lived up there I used low tunnels and they worked up until about the middle of January.
The propane heaters let a small amount of gas leak plus the carbon dioxide.. It killed my plants.
Bonjour! Je dirais qu’il y a un point hyper important avant de se procurer une serre en polycarbonate. Vérifiez la qualité de la structure. Ensuite, bien l’ancrer sur un bon cadre de bois et ajouter du silicone autour de tous les panneaux et avec un peu de calfeutrant autour de la porte (genre de petit balai). La porte coulissante est malheureusement fragile, surtout au Québec. Ensuite, il sera toujours temps de modifier certains éléments comme ajouter une ou deux tiges de métal pour solidifier le toit à cause de la neige. Les panneaux seront inévitablement à changer dans 5 ou … 10 ans, tout dépendra de l’épaisseur, de l’installation et de l’emplacement de votre serre (soleil) . Mais l’épaisseur des panneaux et la structure font augmenter le prix mais ça faut la peine, surtout pour la structure! Et dernier conseil, dès que vous voyez un petit problème, il ne faut pas attendre et réparer!
Good info, I'm in northern NC (close to VA border) we just bought a 10X14 version. Step 1: foundation. So, you are saying that for us folk here in NC the major issue is keeping it cool...good to know. If you have any other advice, I'm all ears!
Check out the greenhouse playlist I have to get started. I am sure Ill be doing more videos about it as it heats up.
Can you please provide information for installing the louvered window you added?
I just followed the directions but at some point I can do a video about it.
Great video! I am in the process of looking for a greehouse to have a base to start my seedlings in early spring. Any suggestions? I live in southeast Michigan.
All I can tell you is what I have. There are some good companies out there if you have the money
If your starting seeds, build an insulated shed and use grow lights, otherwise your throwing your money away. How do I know, well I have a green house.
I keep cacti, and am looking for one of these right now. My whole intent is the ability for me to 100% control all watering, as i have to keep a super close eye on the rain come September. Its an absolute MUST that i cease all watering to my cacti by end of Sept, if not by mid Sept. That gets hard when youre at work 12hrs and theyre left out in the rain. I have so many pots i feel guilty asking my wife to bring them up onto the porch if it starts to rain while im at work. Lmao!! So im looking right now for a decent quality greenhouse. Any suggestions? Anybody?
Oh, and these plants must come in doors during the winter time.
Just found your channel. We’re in Texas 8b and I just bought a Growers Solutions greenhouse. It’s 10x20 and I’m hoping to keep it warm enough in the winter to keep my citrus from freezing on the few nights we have in the winter. Right now I have winter cool crops growing in my raised beds with frost cloth over them (low tunnels). Just wondering if the radiant heat from the barrels is helping? Didn’t sound like it when you were discussing inside outside temps.
Keeps it 5 degrees higher. Makes all the difference in the world for what we grow in it
@@sandybottomhomestead thanks! Sometimes 5 degrees is all I need!
How did you attach the greenhouse to a frame on the ground,,, just wondering I ordered one just like yours, thanks
Screws
I am re thinking a green house
just understand what you are buying
Well that's your problem right there, foundations go underneath not on top of greenhouses.😁
What?
Is there any reason you did not caulk all the seams instead of just the base? I've heard it's helpful for keeping it warm in the winter. Pros? Cons? We're in the process of building the same size/type of greenhouse. Curious as to your thoughts.
Caulking the seems would make it less stable. The week points are the panels I'm case of wind the will blow out to save the structure. The building process is in the directions from the manufacturer
for your hot water: get 24v solar panels with 24v hot water heater elements. Put the elements into the tanks. Blamo, mega heat store.
Thank you but that's way more than I want to put into it
@@sandybottomhomestead in Canada, you'd do it. :)
Thanks for the video
