Possible heat issue...?
Foil's job in cooking is to retain heat, which it does well. Unless you need the extra heat, I would ditch the foil. Especially when the effective range for CFL's is about 4-6 inches, by the time the light travels to the foil, and back twords the plant, it's travelled too far to be effective.
