A grow tent such as the "Hydro Hut" seem to be very nice if it fitts your purpose. Things that are beneficial, 1. completely light proof, so no having to go to the store every other day to get something new to try to seal up the light leeks in your room or closet when you would rather be kicking back dreaming about all the big buds your trying to grow.
2. have all white reflective material all throughout inside so no hanging up flimsy wrinkly material that makes you want to punch a hole in the wall because it wont un wrinkle.
3, Water proof lining on the floors, with water tight seems, so when you kick over your 5 gallon bucket of water because your so mad that the light is still leaking in causing your plants to go hurmy, or your hydro pump go's berserk and floods, you wont have the down stairs neighbors calling the manager because your raining on their thanks giving dinner.
4. Pre made vent covers on top and bottom to put your inline and intake fan so you don't have to cut off a thumb trying to cut through dry wall with a steak knife to put vents in.
5. Heavy duty light hangers that will hold up a couple 1k hoods and not fall on your plants in week 4 of harvest crushing all your babies causing you to punch a hole in the wall, right threw the miler you took so much effort and time to hang up, hurting your hand that you cut the thumb off of, making you slip in the 5 gallon water spill causing you to fall into the ballast dripping wet starting an electrical fire.

Hope this helps some.
