anyone have any word on these? they are in every issue of high times and Ive been considering gettin or making one. to people who dont know they are tents with a retractable cover that keeps your plants in full darkness as long as you want, when you want as I understand it, making the flowering period whenever you want. Comes with hydro option that fits 812 sog plants, fan filter, solar cell, electric winch, camoand all sorts of gizmos. my concern is how light proof this thing is and if it could flower plants at regular speed
