my air temp never varies more than 3f in veg room with it set at 76f. air speed im not sure, i have 1 small oscillating fan on medium setting. but ive always used 250w cfl to veg seedlings, i have used t5's and 600w hps also. i have never ever had a single issue from light burn from a cfl, im not saying its impossible, but its unlikely, especially wen running 23w cfls. generally if theres an issue its prob more to do with something the grower is doing wrong than the light intensity of a cfl. Maybe books or google will say different, i only know what works for me but ive grown more plants last year than most will grow in their lifetime.
Its usually heat that causes most plant/light issues rather than light intensity and cfls give off very little.
