    barely one if you keep it hella short. If they are just seedlings a few.

    Definitely if you plan on having 1-3 plants, generally 10k lumens per a plant.

    How big is your flower area going to be? Most people start flowering between 12-18 inches. With cfls the shorter you keep the plant the better because they don't have much light penetration and the further away light diminishes very quickly. You don't have to have 10k lumens (more of a benchmark) but the less you have the lower the yield will be. Also plan on lsting your plants to keep them short.
