Saw em on ebay and they look pretty nice for the money. Does anyone have one? [ame=http://www.amazon.com/GRN-Elements-GRN3-Reflective-Hydroponic/dp/B0063YIRXO]Amazon.com: GRN Elements GRN3 Heavy Duty Non-Toxic Mylar Reflective Hydroponic Grow Tent - 60" x 48" x 24": Kitchen & Dining[/ame]
i just bought one off ebay. I got the 36x20x60. nice and sturdy. no light leaks and seems to be made pretty well. 3 of the walls are velcro'd on so you might need help to get them even but i was able to build it in 15-20 min by myself. I haven't started a grow yet but will as soon as my lights come in that i ordered today, and the fan that i will order on monday
I have that same brand in 4 x 4. It is decent for the money. It does have pin hole leaks along the stitching. Also they dont provide any way to secure the lower vent flaps.
