Buckets of dirt do not work better, I will put a 5 gallon bucket of pro mix to your dirt, and I gaurantee I would have a higher yeild. Anyways the topic had to do with rotary systems. I would love to put the rotary systems to work, to see which one yeilds better. I think it could yeild way higher amounts then the horizontal space and lighting. Thats what everyone is talking about. If you are embaressed of your end numbers thats ok, we just want the numbers. If it takes 2 months to flower and you only hit a lb on 2 600w bulbs then its not going to be worth it. But if you are saying you had a heat problem and you were not able to fix it immediatly outside of the system then you might be a novice grower which is fine. Just put your heading differently. "Challanges with the different rotary systems" not a side by side comparison. We want to know the facts. Most importantly what can this machine or other rotary machines produce. So if I told you with a 1000w hortilux bulb I was able to produce 2.22lbs per light on a 20 light setup, that had phantom digital ballast, a blow through room, which means it was not a sealed room, it takes air from one part of the outside air through the room and vents to the opposite side of the room to the outside. More of a California thing I geuss. I had 4x8 trays on a tray holder, unsealed concrete floors, dehumidifier that had to be manually dumped, no a/c, 20 wall mounted fans, the total space needed was 10 4x8 trays the trays are actually 4.5x8.5 so lets say 5x9 thats 45 sq ft of the floor x 10 so 450 sq ft. I vegged for a month, and flipped for 8 weeks total 12 weeks from clone to harvest. Can the rotary machine come close to that or even half of that? The 2.2lb per light was a fluke thing, and yes that was dried and cured. I average 1.5 to 1.75lb per light. Or if im doing sea of green its only a 8 week process from clone to flip 2 days after transplant yeild is .87lb per light to 1lb. 100 per tray at 2 1000w lights, 6x6 pots, pro mix, a good indica strain. So the sea of green per month produces .435lbper light to .5lb and the 12 week process produces .333 if you were only to get a lb per light to my highest of .73lb per light per month. So what was your weight in months?
