I live in the upper midwest, zone 4, where it regularly gets negative10F and colder during the winter, we get heavy snow, and winter is almost half the year. I put my Costco Yardistry greenhouse together last fall and was in it in early March starting some seeds like cabbage, kale, onions, swiss chard- whatever has worked for winter sowing in the past. I also started some seeds inside and in the usual winter sowing containers out in the snow. Of all three ways to start seeds, the greenhouse worked the best. So next year, I probably won't be starting anything inside, and I'm definitely ditching the winter sowing containers. By mid-April I was able to start the warmer weather plants like tomatoes, peppers, and even louffa! Squash, corn, beans, basil, dill, sunflowers, petunias, marigolds, melons all started successfully in the greenhouse without any extra heating. When it started to get over 75F I did notice that even with the roof vent open, it was still getting too hot in the greenhouse (mine is in full sun), so I took the triangular panels out of the gable ends and replaced them with screen cut to the same shape (I did have to take the roof apart a bit to get the panels out and slide the screen into their place, but it was pretty simple to get it apart and put it back together). This works really well to vent the excess hot air and it still stays plenty warm enough. It cools it sufficiently without even opening the roof vent now, even in the 90s. When it gets colder, I made four paneled triangles I can just slide into place like little storm windows (I won't have to take the roof apart again since they just slide in from the inside). I still want to put a solar fan inside to help even more with circulation, and a small heater to help things get started even earlier. I love this greenhouse. I don't regret the purchase or giving up garden space for it. I would definitely recommend getting one if you garden a lot. I have a 40ftx40ft veggie garden and had plenty of space to start everything I needed. Your videos were really helpful in the build. Thank you!
Thanks for posting your 2 part Yardistry greenhouse build. I can’t wait for the snow to melt and we can begin building our greenhouse. I do have one question...Do you think having electrical power in your greenhouse is important?
We don’t have electrical run to the greenhouse. We are working on a passive heating method with water bins to keep the night time temps warmer but it does take up space. I think it depends on where you live and what you want to use your greenhouse for.
Did you consider finding a way to bring water into the greenhouse? There isn’t really a way to bring in a garden hose, so I wondered how you handled watering your plants.
I watched all of your build videos. Wish me luck and I will try to record a series to help the next person. Happy gardening!
Good luck!

Your videos were so helpful just put ours together this weekend ❤
Thanks for the video. I saw this greenhouse at Costco last year and wondered how it would hold up.

Snow load rating?
I’ve been trying to find, in your videos, where you secured the greenhouse to the 4x6s. But I can’t find it. Can you help me?
It’s not in the videos but I recommend using tornado straps.
