GrowIT® Organic Growers Pro RoundTop Greenhouse is rated 4.2 out of 5 by 5.
Rated 5 out of 5 by from Holds Up Well To Heavy Snow! We bought this product because we had very cold weather in April, and it killed our garden. So we put this up and started over. In May, we got a foot of snow in Colorado. Not the light powdery stuff, but the very wet concrete type. I will say that as the snow accumulated, it would just slide off. This product held up great, and the warmth inside was really very nice for my newly replanted garden. Very happy!

Rated 4 out of 5 by from Great Value I bought a second one of these because of the reduced price and discount on freight. It's a great unit that is very secure to the ground due to ground augers attached to the frame. The ratcheted cover system works very well to hold it securely. This time I had an issue with the cover being defective and the company sent me a new one within a matter of days. That was a nice touch. There are two different kinds of covers that come with this kit. One is opaque white and only Lyall about 60% light transmission. The 2nd cover that was defective was clear with a quarter inch matrix of white reinforcement. On some level I prefer that one because of the increased light transmission but it doesn't seem as sturdy. The instructions are mostly visual so you have to study them carefully in order to build the unit properly. The trickiest part is making sure you use the Straight ends of the two pointing down when building the side walls on the arched pieces. The one disappointment about this unit is that at each corner and the ends of the roll-up sides there are air spaces where the unit isn't truly sealed. That can lead to problems if you are trying to grow frost tender transplants. This issue stems from the the end walls and cover being separate pieces. I have started hundreds of flats of various farm crop transplants with great success. I use pieces of foam to plug the Leaky spots. It works pretty well. The other thing is the sidewalls being roll up or rather leaky as well and the entire unit is not completely sealed like a typical Greenhouse. Despite all of this it's an incredible value and I don't think you're able to find a better price per square foot no matter how hard you look. Even if you were just to buy something really primitive like what they call a cold frame. Given all the factors of price sturdiness and durability of the cover it is a great value and I would highly recommend it overall. I understand the inventory of extra covers it's not that large and you might consider buying the spare. Otherwise you'll have to use clear poly and build some kind of framework on the end walls to re-cover it. The other positive about this unit is that it is very sturdy in windstorms and can take quite a bit of snow weight.

Rated 4 out of 5 by from Green house is great Greenhouse is great. Packaging was not so great. Damaged twice, and then when I got it it was missing 9 parts. Customer service department was great working with me though to get the parts!

Rated 4 out of 5 by from Great Value I bought this recently and just finished building it. It's well worth the cost. A great value all in all. Roll-up sides are key based on previous experience with hoop houses that don't have them (heat build-up), but that creates air gaps on this unit & it's not completely sealed. Directions are somewhat challenging to interpret. Customer service & sales staff extremely helpful. Some of the parts did not have necessary holes drilled in them. It will serve my needs well, and I may buy a 2nd one.

Rated 4 out of 5 by from Good value I bought this a month ago for storage. So far works great! My only complaint would be the instructions are not as clear as one would like. Otherwise perfect. Let's see how she holds up to the winter weather.

Just received my 2nd unit & building it. Still puzzled as to how to secure the base of the end wall panels. Are you supposed to tuck it under the base of the frame & pin with landscape staples?

Asked by: majikfish
Hello, We are not completely sure what you are referring to. The end panels are wrapped around the end ribs and then cinched down in placed by ratcheting the straps until taught. We have included the assembly video for a similar unit below. If you still require assistance please give us a call at 1-800-932-9344. https://www.youtube.com/watch?v=U08wx1MqNW0 Thank you
