There's a lot of factors that come in to play when asking about producing a nice crop. How many plants? How much space? Ventilation? How many lights? Lumens per sq. foot?

When using CFL's to grow, I suggest using more than you think you need to spread them out evenly among the plants for even growth. CFL's will grow a very satisfying crop but you have to be prepared to move lights daily because the CFL's do burn. You also want to shoot for more lumens than called for. The impact of CFL lighting is nothing like HPS, so make sure you keep them very close without touching. You will get very strong and rapid growth the closer the lights are.

Shoot for a minimum of 4000 Lumens per sq. ft....you will be very satisfied!!!
