I bought this in March of 2017. I have mine in a semi-sheltered area and we put 2 by 6's under the long side walls, tied and crossed tied it down with paracord to the eyebolts we screwed into the boards. We put long sandbags for weight on the boards between the eyebolts and haven't had any trouble with the wind. You will have to do something like this or IT WILL just blow away. The cover started to deteriorate on the sunny side at the corners and along the top after about 7 months and by December I have had to order a replacement cover for $50.00. The customer service lady was very helpful. This may be an annual expense for as long as the frame holds out. I will reinforce my new cover with clear Gorilla tape in the trouble spots hoping for longer life. But for $120.00 I really do like this greenhouse. We used cinder blocks and wire shelving from a closet redo for shelves and it is the perfect place to keep all my garden stuff and we did start all of our veggies in it last spring.

The wind blew down the greenhouse despite being anchored . Anchors provided were to small. We reset up green house using rebar for anchors that were 1 ft long. We buried the flaps under 2 feet of dirt to hold them in place. The flaps should beat least 4 feet wide to give enough material to weight down. The green house worked well. The windows however do not shut completely. The Velcro on the flap did not match up with the frame. I had to tape the window shut until the weather warmed up. Zipper on the doors are holding up. For the price
its and ok greenhouse.
Down graded to a l star. Do not buy if you are in an area with any wind. Almost a year later the top seam is ripping. The screen flaps on the windows do not line up so windows cannot be shut during the winter. Had to duct tape the windows shut or the wind blows inside threating to lift the green house. We put 1 foot of dirt on the flaps on the ground. The screens are ripped out, This green house would only work if you had it in a completely sheltered area. The initial design is poor. The windows should have zippers to create an airtight seal in winter. The flaps should be at least 4 feet wide enabling a better anchor. The stakes should be rebar otherwise they do not hold. The top should be reinforced to withstand rubbing of ropes needed to tie down the green house. We had to put ropes across to hold it in place. I should have
taped the rope last year because it rubbed a hole in the top of the green house and on the top frame where the wind caused the rope to
rub. Door zipper ripped. Could have spent the same amount of money and built a hoop house twice as big. I am a retired farmer and have built my greenhouses for over 30 years. Disappointing

I've had it set up for 2 months and it is doing well. The description states "Heavy-duty steel framework can last a longer time" - I assure you this is not the case. The tubing of the frame is literally the same diameter as my little finger. The welds seem cheap and don't continue all the way around each pipe - rather there are 4 tack welds for each tube. The walls of the tubes also very thin. Is it steel? I'm thinking aluminum. Regardless the frame is the weak link. I have always hung a simple house fan from the frame of my previous "green houses" - I seriously doubt this one could take the extra 5 pounds of weight so the fan takes valuable floor space. Tie this thing down! On the windward sides I used 4x4's on top of the "bottom flaps" to help hold it down. Next I ran 2 ropes 1 foot in from each end, over the top and anchored them to prevent it from flying off to the neighbors. This configuration has withstood a couple days with 20MPH winds.
The cover - I like. It seems well built, zippers seem good. Assembly was easy.
My last green house was from another manufacturer. Every piece of Velcro to hold up doors and windows disintegrated within 9 months and in the midst of year 2 the plastic started falling out of the squares of "reinforced cording". Little squares of plastic everywhere! For this reason I'll update my review after more time has passed.

Great customer service. I had one small problem, I emailed them and they got back to me quickly to resolve it. Was easy to assemble and works really well for getting an early start on my seedlings and small plants. Even my husband who is 6' tall could walk inside. It is lightweight and easy to move. I used some plastic lunch trays to put my cardboard seed starters on, and I just add water to the tray to keep everything moist. (See pic).

To make sure it would hold up to our normal thunderstorms when assembling we used a slow drying glue (6000) to allow for assembly mistakes which we made, the glue dries in about 12 hours. We anchored it well and so far it has taken stormy weather well. We have our seed trays coming along quite nicely and are very happy with it so far.
