Lighting Question

[turtle420]

I think the world of CFL is just starting to take off - they are good if you only have a small space to grow.

The main rule with CFL's (so ive heard) is to double the wattage when you start to flower - otherwise the yeild will be very small.

Also CFL's are great for starting a seedling as a high powered MH / HPS would be too strong at first for the plant.

True.... I've got a closet that's 20" deep, by 40" long... with a 48" height... and I've got a 400W MH and an 600W HPS in there....

As to CFLs' main rule, that sounds good. Never heard it, but it does sound like a good ballpark figure.

CFL, as you say, is great for seedlings and clones... true again.
