It will cost you some time, I suggest you find the females, let grab some branches for clones, and let the mothers continue to flower to maturity. When you go to 12/12, you'll get a nice growth spurt ( about 2X ), so those small branches you see in veg will get big enough to clone.
Best things I ever did for my clones, have patience. The worst things, putting in ferts too early, and getting one cooked by the cfl being too close.
On the other hand I had take real nice, which then gave me two, and so on.
I just picked up a couple of "100" watt cfls from 1000bulbs.com. US$ 5.60 each. These have a special coating which is supposed to help control odors and in my two days of testing I have to say it works. I use the cfls for veg in a small cabinet, with a fan. I've always had a slight weedy smell...
some heavy gauge copper wire is ok, too. AWG 10 or 12 is plently stiff.
Mogie rocks. I'm into week 5 of 12/12 with a tied over sativa, and the nugs are small, but there are a lot!
That's tight, dude. SCROG may be your best bet. I have a 250 hps, and I can get within 2" of the tops safely, but I think the 400 needs 6" or more.
What do you mean by 35"? Bulb to bottom? Or usable space.
