I am only using a 150 watt 2700k cfl it is 2 inchs away from the canopy, I removed the screen I have between the leaves and light. I plan on using a total of 350 watts for flowering though, I have to work out my exhaust issue. Right now my temps are sitting at about 90f when the lights are on and 75f with them off. I figure the 15 degree drop will help guarantee that their females. I have another plant I am grows, it is some orange kush that is under full spectrum led's. I designed the led panel myself, fuck paying 300$ when I can build the same thing for 15$. I am also going to pressurize the big bud plants box, with a Carbon Dioxide generator. I already have it setup but I am going to wait until flowering because I do not want my plants to outgrow their box before they flower. Idk what do you think.
