Most people say that for MAX output... You need your CFLs an inch or less from the plants. I am no expert... But the amount that the lumens dissipate over a 3 inch distance has to be trivial. I agree, you can't place them a foot away... because that is a significant distance. But a couple inches? To stop burning? I feel it would be beneficial.
