4 inches between the plants and the light i think is quite enough. by the way, what type of grow-lux light are you using? the standard type or the high spectrum? however, using both is a good combo. the high/wide spectrum light works as a supplementary light source
sticky me Reviewed by sticky me on . Grow Lights I just recently got rid of my 8 45 watt CFL's in exchange for 4 40 watt Gro-Lux T12 4' Wide spectrum florescent lights. I have attached pulleys to the ceiling of the grow box, which is 4x4x6 My question: Is this going to be a sufficient amount of light for a couple clones? I have the lights 4" from the top of the plants. Rating: 5
