jondamon Well-Known Member Jun 10, 2010 #2 thats not enough info. what are you using ? hps mh cfl's wattage? a good rule of thumb is to place your hand at canopy level palm face down if you cannot keep your hand there because its too hot then move your lights up until your hand is comfortable . J

Arrid Well-Known Member Jun 10, 2010 #6 Hang your light as close to the plants as possible. Put your hand under the light and see how close you can keep your hand to it. If your hand cant stand the heat, neither can the plants.
