4X8 Shit @trailanimal i would be running 3 in there easily...i figure 3 feet diameter is needed for bigger autos(4 for the biggest). With some training, one in the dead center, and 2 tied out on each end(planted at 2 feet in and 6 feet in).....kickin' ass!! It would be some effort training, but man it sounds like a fun grow!! II should be there late june i guess to start working on it?
