  • It is great
Color: Gray Size: 6×12FT
It seems pretty sturdy, we have had wind gusts up to 30 mph and it didn't come apart. But, I do recommend getting some anchors for it though or it will move or blow away with wind over 15 mph. It was easy to assemble and the size of it isn't too bad. It's worth the money.

  • My portable hot tub greenhouse My portable hot tub greenhouse
Color: Gray Size: 6×12FT
It was a lot of pieces with pretty good directions. I like the finished product. I did have a couple slight bent corners I had to straighten. I did have to expand a couple holes and trim a couple panels. No big deal. I did add a latch inside for when I'm in and don't want the door open in the winter. Couldn't figure out the props for the windows and didn't end up using them. I did caulk it all per others suggestion. I'm really happy with the end product. ... show more

This was not difficult to put together. The finish on the framing is nice. We will be adding the recommended added backing for high wind. I do wish the vent holders worked better, diffaclt to get tight enough to hold open. Made some wood stops to hold open. Did add a solar fan and sun shade because it was working to will. Have happy with the cost. ... show more

  • Waste of money
Color: Gray Size: 6×12FT
Thought I’d save a bit of money by going this route. Assembly was a nightmare; some of the pieces were bent making it impossible to put together. To the manufacturer’s credit, they sent replacement parts, but they took over two weeks to arrive and we had to pray that this half-assembled monstrosity didn’t get destroyed in the meantime. Turns out it basically got destroyed anyway over the next few months; panels regularly get blown out and lost and the whole frame is sitting askew now. This thing is not even worth the time and effort to put together, let alone the wasted money. ... show more

  • More work and cost then just buying the green house and putting it together. More work and cost then just buying the green house and putting it together.
Color: Gray Size: 6×12FT
Over all happy with it, however, keeo in mind a few things. The price you pay for the green house isnt the total price you will spend on it. 1: it will need a base built that it can be attached or anchored too. Its very light and the wind can easily move it once erected. ( made a 2x6 frame on 4x4 skids and decked with plywood.) 2: you have to seal each panel with silicone, otherwise the first wind you get your panels will blow away. I sealed both inside and outside of my panels with clear silicone and havent had an issue since. (It took 7 tubes of silicone to completely seal the 6x12 i bought.) 3: the hinging and leavers in the vents are cheap and i recomend replacing imediately. 4: the door after being sealed with silicone is sturdy, however, it lacks a hold open feature and like to slam in the wind. I suggest using some sort of hold open. (I used a bungge cord.) 5: even after sealing, and mounting to base it is still essential to wind brace the whole structure. I used screw in anchors, cabkes and turn buckles. The positives if after you do all of the above its a solid unit, looks good, and does what a green house should. After the cost of green house and doing all the extras to make it wind and weather proof my final out of pockets expenses were right around 1,000 dollars. ... show more
