How much light?

I have 2 plants on a shelf under my desk and am worried if they have enough light or not. They have been at 12/12 since the beginning. The shelf is about 2ft high and 2ft wide how much light would yall suggest? I want to use cfl's cause i dont want to spend to much money but also have a 1ft flouresent light. thanks

use 10 CFLs minimum in that setup, half of each white.

which cfl's? watts? And isnt 10 a lil extreme since they are 12/12 and wont get to big?

Those lights need to be on all 24 hours before veg, especially if you are just using a flouresent or cfl. i run mine all 24 to start under 400 watt hps and up.
