Since last night, I substituted the Gro-Lux lights for 4500k 40 Watt Cool White Fluorescent bulbs. My next question is: Will the bulbs be sufficient? Also, Do I have the lights low enough? I do have clones in the Humi-Dome, I only started 7 because I am still a novice and didn't want to butcher my plant too much!

Metalliogre Reviewed by Metalliogre 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
