Rated 5 out of 5 by from Great greenhouse I bought and put this up, I would recommend having a friend help. If you have a hard time with this you do not know how to read/follow instructions

Rated 5 out of 5 by from Excellence-in-a-Box This product is very well engineered. The construction diagrams and included information are totally complete and easy to understand. A great product for wintering over those less than hardy keepsakes. I only had three bolts and nuts left over. The designer for this greenhouse is excellent.

Rated 5 out of 5 by from Green House in a Box It works fantastic as a green house. I start my tomatoes etc. and they grow throughout the season very well indeed.

Rated 5 out of 5 by from Great Green Hose, easy to put together This is the 7th greenhouse that I have bought. They are very easy to assemble, and I believe a person can grow about anything in them. One suggestion would be for the seller of the greenhouse to offer new skins. Have to change over to normal plastics.

Rated 5 out of 5 by from Sturdy & tough shelter for our BBQ We now have 2 Shelter Logic shelter/tents. Our 1st one, 10x20, has stood up to our heavy winds this spring and our new one, 10x10, seems to be just as strong and sturdy. We use them to protect our BBQ Smokers & Grills. Makes our life easier during the cold & heat.

Rated 5 out of 5 by from Quick and Easy Option This is my second purchase of a Grow T Greenhouse. The first I had for four years and I just needed more space this year for my tomatoes and peppers. I use a small space heater in the spring to add enough warmth at night especially since I "push" my growing season a bit (Zone 7). The four corners at the base and the bottom flaps allow cold, windy days to drop the temperature more than one might like, but on calm days heat loss is minimal. It looks GREAT, is easy to assemble, durable and its affordability has allowed me to add a second to expand my modest growing and selling business. I bought a replacement cover this spring for my old Grow T because I used it pretty hard. Replacement covers are affordable and you can expect 5-6 years from them if you take care of them better than I did,

I need a replacement door for my 10x10 "greenhouse in a box." Part #802180, but that is not listed on your site. The fabric comes off in summer and bird netting goes on to protect the blueberries. But the door is in constant use needing replacement.

Asked by: 72Rover
Hello, Unfortunately, we do not offer the door panel on its own. It is already pre-packaged in the cover kit which also includes the main cover and solid back panel. The cover kit for this greenhouse is #90586. Hope that helps!

I'm thinking of adding another layer of poly over this structure and attaching a squirrel cage blower for added insulation. Do you think this material will hold up and not let too much air pass through?

Asked by: Maurice
Hi Maurice, It should be adequate for this purpose. The hard part will be getting the two layers sealed enough at the edges so an air barrier can be formed in the first place. There aren’t many adhesive choices when it comes to bonding polyethylene. To discuss in more detail feel free to give us a call at 1-800-932-9344. Thank you

I have the Growit High Arch Greenhouse. My plants are not growing very well and are no where near the the size or condition of same plants growing in full sun. Did you test this fabric before selling this greenhouse? How much light actually gets through?

Asked by: Wendy4
Hi Wendy, We are very sorry to hear about this. Our covers were tested and the 5.5 oz. Ripstop Translucent Polyethylene fabric yielded the best growth across various crops. These covers have a 67.2% light transmission. If you have any additional questions or concerns please feel free to call us at 1-800-932-9344. Thank you
