Acccording to Crabby's link, it was just the HydroHut with the white lining that was made in a sweatshop in China that was killing plants. Improper ventilation coupled with noxious offgassing from some crappy plastic could kill plants I suppose. I use 2 different models of the darkroom, have been 100% satisfied with both. If you are going to flower in a tent, purchase a carbon filter, it will help immensely with air quality and smell control. Be sure to keep negative pressure in the tent tho, if you have positive pressure you will smell weed leaking out everywhere.

Heres a link to one retailer selling the Darkroom.
