I have done a great deal of reading, and I have yet to see where it was suggested that you have 10,000 lumens per sq. ft. That would mean to have optimal growing conditions you would need 1000 watt HPS in a grow cabinet that measures 4 x 3.5 feet, roughly. Damn, how the hell would you keep that cool? If 10K per sq. ft. is the number, then all the hydroponic sites are dead wrong on their suggested coverage area per light, and advertising falsely. I wish some of the other experienced growers would shed some further "ight" on this (no pun intended).

I am just a noob idiot, but I love to read.

peace all,
