well it looks like u did your homework and i foresee a very nice experience coming of this for u (and the rest of us reading about it) im assuming those flouro lamps are so high up so u can take a picture? just remember to keep the flouros close to avoid stretching your plants. (within 1-3 inches) use a little thermo and actually keep your temp at about 80. ive never been able to get lower than 80 with a lot of flouro, havent wanted to either. as long a i keep it 85 and under i dont sweat it. keep researching to learn more about what your doing and good luck!
