Here is another tech note for post # 183. The flower grown under 10 hours hps and 4 hours of red inc/cfl cost my uncle 192 watts less a day then the flower grown with 12 hours of HPS. Basically 10 hours of HPS instead of 12 saved him 800 watts a day. The 100 watts of red inc's and 52 watts of red cfl's adds up to be 152w x 4hours = 608w a day instead of 800w a day. Saving him 192w a day.... Gotta like that..
