Flood lights and incadescents are virtually worthless in a grow room. Technically the cfl's are the only light in the room. Cfl's shoul be 1-2 inches from the tops. If the plant does not have flowers, you could top it to bring it down to size, or train it as others suggested, depends on how tall and lanky it has gotten. stretched plants are normally weak and will not support the weight of the bud. broken limbs late in a grow SUCK!
