GardmanUSA 7600 Greenhouse, 4 tier

I put my outdoor orchids in it at night. Awesome for humidity, but need some help to keep warm. I use the milk jugs with hot water to bring up the temperature just before I zip it closed for the night. So long as I do not open it afterwards, it will warm up and stay around 5 degrees warmer until early morning when the heat from the jugs has dissipated. I also added some dark purple Christmas lights with a timer, they come on around 2am and off around 6am. The lights bring up the temp a few degrees for the early morning. The temperature pic is from an hour or so after I closed it up for the night. The second temp pic is from 5am when the lights were on. Happy plants.

Bought this to use for seedling starting inside a sunroom in late winter.Have had it about two months, and so far it's fantastic for the price point.Super easy to put together but be careful about pushing the poles too far into the plastic hole joint, I got too exuberant and cracked 2 of them, then had to zip tie the poles to the sides to support the weight of my flats.Greenhouse cover is nice and thick, well made. I cut along one edge/seam of it to vent out the back and let the sun in from the windows, so I can vent both front and back on warm days.I use the top shelf for taller plants like sweet peas etc as the shelves are not adjustable. This is a downside as the plants get bigger, but this is a great option for growing for the first few months before hardening and setting out.The shelves support the weight of hanging shop lights nicely and the metal shelves support the weight of the flats nicely. You may have to strengthen them here and there aka the zip tie method works well.Overall this is a fantastic option, small footprint, fits in the corner of my sunroom and with 2 shop lights on each of the 3 bottom rows and 3 flats on the top, it is currently holding about 15 flats of plants. Not bad for $50! I would probably not put this outside though as it is pretty lightweight. It would probably last a day in our climate!

I bought two of these in June of 2013. They are extremely well made. I had one break on me when the painters came and moved them without my knowledge. I had about 150lbs of soil, sand, and pots on the bottom two shelves for my bonsai and they didn't move them from the bottom. The coverings have help up in 60mph wind that we frequently have in Oklahoma. The bonsai also have survived in all of the elements that we receive here; 115 degree heat, 5 degree cold, and severe drought. I have no clue what the negative reviews are about. Do not face the broad side into the wind and they will never tip over. As for bonsai, people who know anything about them will tell you that if bonsai can survive with these greenhouses in the extreme Oklahoma weather, they must be worth their weight in gold! Bottom line, if you need an amazing greenhouse that will hold up to anything, BUY THESE!

This greenhouse is PERFECT for greenware. I use it in my studio for freshly made clay pots and sculptures. With the door zipped, I don't have to wrap the work in plastic as it keeps the clay moist till I am ready to work with it again (I do put a bucket of water inside to keep the humidity up.) As other reviews have suggested, I tied the shelves onto the frame. The shelves are light weight and easily move around if left loose. The shelves are strong enough to hold my large bowls and vases. I don't think this greenhouse would stand up outside in our winds unless it is sheltered and staked down.

I love this greenhouse. It's the perfect size for my grow trays. Unfortunately, I put my plants in before securing it and a severe storm popped up out of nowhere. The greenhouse flipped a few times and I lost over 100 plants. I would suggest buying t-posts to help secure it. I added two behind it and used zip ties to attach the greenhouse. I also secured the shelves after reading one of the other reviews and that helped. I have had no issues since then. It has been working beautifully.

excellent for the price. i used wire ties to hold the shelves in place. this isn't the sturdiest thing on the planet. mine is in the basement with grow lights and heat mats for seed starting and over wintering of plants. it works well. not sure if i would use it outside. serves my purposes well.

Cover is pretty good not super thick or thin just right. I zip tied the shelves to secure them a little more. Four stars because the ties to hold the door flap up and to tie the cover to the poles are all uneven. This I am sure will vary either you get lucky or not. Not a deal breaker for me. It is just what I needed fits great on my tiny porch.

I was hoping that this would keep my plants warmer at night and it does not.
