Hello all! I am a new grower and I have done a ton of reading and studying first, but with no surprise I am having some issues on my first grow. I designed my grow area with a non typical light setup as I obtained a bunch of 175w MH ballast and fixtures for free which I designed around. I setup a 6x4 grow area with 6x 175w MH on adjustable height pulleys for a total of 1050 watts combined. I also figured I would add CFLs as needed, but as of yet the plants are still small and I have not seen a need to add the CFLs. I have done a lot of reading online for my first grow, but I have not found much information about the difference in lighting with many lights vs one large one.... this is where my questions lie. I've seen multiple charts with info on how far away to put your lights, and I have used 1000w as my reference point, but I am wondering if it would be the same with my multiple light setup or completely different? Currently the lights are 8-14" away from my plants. That sound good for my setup? I never found information on the light distance charts weather or not it was referring to the distance from the top of the plants leaves or to the base of the stem at the soil. Can anyone shed some light there? Is my light setup adequate? Or am I hurting myself by using these free lights? My plants are only about 4" tall at day 21 from initial germination (white widow), and I feel like their growing slow, but again I am very new at this does that seem like a normal height at this point? I appreciate any suggestions, comments or helping information you guys can add.
