Totally agree, also, my 1000 Watts cost $50 a month each to operate, about $1.67 a day (30 day cycle), or $0.069 an hour. If you I opted for only 6 hours night on an 18/6, I would be saving $0.42 a day, $12.50 a month. The real question is "feeding" the plants 25% less worth a monthly production...
