i think you're refering to 100w incandescent equivilant. its actually really 24w.Witch one of these will work
..cfl 100w 24w 2700k or 100w 23w 6500k..witch one will work on growing about 3 plants
You know i just tried upgrading my 14w bulbs to the 23w and they burned my plant, am i doing something wrong?… they weren't even with in 5 inches..buy one or 2 big watters only they are not efficent as the 23watt.
23 watts have a 69lumens/watt ratio....as the it gets bigger u add wattage but lower light quality.... just get 1x 200w CFL and put that on top and use 23w cfl around the plant and in dark areas.
150w for 1st plant and 50w per plant after (Vege) 6500K
200w for 1st plant and 100w per plant after (flowering) 2700k
