I added a oscilating fan to the project. It has a clip to hang it on rack bar, or side supports. 11$ at Walmart. I'd like to also add, while the closet is stealth, it doesn't mean to keep it all closed up all the time. Like any inclosed area, it will get warm. So close it when you 'have to'. Leave it zipped down when you can(summer can be brutal). If someone(friends, relatives, meter readers, repairmman) comes over, it only takes a few seconds to shut off the lights, and zip it up, and roll it away(TRUST NO ONE). And the little fans, make no noise really, so you can leave em' on.' You can't even see the fans, unless you get down on your knees, or stand on a chair. I started with a hydro system in the closet, but being so hot, and only my mainroom is ac'd, with no room for the rollitout. I yanked it after a day, and switched to soil, and thru in the new fan. I have a dozen seedlings and clones vegging in there now. The seedlings I have in there are feminized. I've noticed the leaves on the fems are 1/2 as small as normal seedlings, and a little slow growing, I might add. Has anyone else notice this with Fem seeds? My first batch of fem seeds, so I just don't know. Other seeds(not femmed), are all normal, and speeding along. Its just not 1 or 2 seeds either, its every one. They look fine, just, well....minature.
