Considering this, how many watts for CFL grow?
When using CFL bulbs to grow a plant with a high light requirement (like cannabis), you want a minimum of 60 watts per square foot. Ideally, you want 100 watts per square foot. And it doesn’t hurt to go higher (though there’s not much point going over 150w). You really can’t give your plants too much CFL light.
