If you're worrying about having your fluros too close to your plants, maybe you should consider getting a fan or a ventilation system to eliminate the possibility that the plants will get burned.

Fluros aren't the same as hps, hps produce a lot more heat while fluros produce a lot less. It shoudn't be a problem to have the fluros close but be sure to have some kind of air flow bringing in fresh air so the plants wont be in a stangnant, stingy hot place.
