To respond to what Retro_killa said, you can give your plants direct light, just as long as it isn't an HID bulb or sunlight. If you use a 600W metal halide, HPS or using the sun: You don't want too much direct light as it's 'unnatural' for the plants.
Flouro's are fine, I have a 42W flouro that's about 5 inches from my ROOTING clone, and it's doing absolutely fine.
Water them when the top-layer of the soil dry's out, since they're in a humidity tent: You'll only need to water them once every two weeks, if that. Just keep an eye on the plants, and if for some reason they dry out quicker than what I stated: water them

.
If you want, find an old small fan or something small that moves air, and pump new air into that grow chamber. That way you don't have to worry about forgetting to give them new air

.
Give them nutrients in a few weeks time, I'm just started to use half strength, and my plants are ~11 months old. But I know people on the forums who have used full strength since the first month they got them.
I'd suggest getting a carnivorous plant too, aphids suck!
Happy Growin',
