as long as you don't stress the clones too much they should stay female. For two plants I would recommend Compact Flourescent Lights, as they put out more light for the room they take up and are not very expensive. Get "Cool White" or "Daylight" color temperature ~6400k for vegetative growth and "Warm White" ~2700k for flowering.

You can leave the lights on 24 hours a day in vegetative growth and your plants will grow faster and do not need darkness.

Here's a decent Grow Guide to get you started.

Do not over water or over feed your plants. And read as much as you can. This forum has a lot of good stuff on it, use the search feature to find it.
Cornelius Reviewed by Cornelius on . New to Growing...Need some advice... Well, my uncle has been growing weed for 16 years and he just harvested his outdoor plant and it was some of the best commercial weed i've ever smoked. So i have decided to grow it indoors with proper nutrients and stuff to see how it comes out. He's giving me 2 clones of the plant after they root,the plant is female obviously,since it's a clone do i have to worry about any males? I have a growbox about 6 ft x 3.5 ft with a shelf on the top for storage of nutrients and other ect. I need to know Rating: 5
