I ordered this one on ebay.com "Product Code: GYO1002" it was difficult to assemble because a reterd made up the directions. There were 8 sections of pole labeled "B", four of them were 6" longer than the other four. It took me a while to figure this out and I accidentally ripped the tent because when I assembled the poles they were 6" too long. It has a strong plastic smell. On the first day I put the plants in the tent four out of six showed signs of over fertilization. The leaves curled upward at the tips, eventually the edges of all leaves died and it spread to the whole leaf. Does this sound like PVC toxicity? Seller "gyosupplies" does not accept returns.
