OK now. Please help me understand this one. 1 ounce = 28.3495231 grams. Right? OK, So, IF you had 27 ozs. in one harvest then that would be 765 grams total from one of these racks. Right? OK. 9 weeks of flower = 63 days = 756 hours total lights ON time in flower ONLY. OK so, (3) 1000w lights pull, lets say, 3000 watts per hour = 2,268,000 total watts used to make the 765 grams possible. So, you start with growing a clone, veg a little, THEN start figuring the power used(in flower only, for the one rack) to make your total harvest. Also, please keep in mind that it took all three lights on that one rack to get it to it's current potential, regardless of the other racks in there with them. Since we made 765 grams with 2,268,000 watts of flower power(Lol), then you would have used 2964.7 watts to make a gram, or 2,268,000 watts to make 765 grams. Think of all those watts actually used to make a measly 765 joints! So honestly, how do you guys come up with that gram per watt figure? If we could really do that then we would be growing 2,268,000 grams, or 80,001 ozs., or 5,000lbs. in 9 weeks of flower! What's that, 1,666.7 lbs. every three weeks! I'm not trying to offend anyone but just simply figure this one out. It's not bad though that the one rack is growing at a joint per hour. 756 hours of ON time and 765 grams. That's damn decent indoors. Although, I can only figure that to be a gram per hour per rack, not a gram per watt, cause it took 3000 watts to grow that gram(or three) in an hour. Am I at least half right on this one fellows?
