I've got some casters and plywood as well as access to some powerful little electric motors. I have to choose the RPMs I want. Has anyone tried growing on a lazy Susan type set up? I figure 1 RPM is sufficient for a 4ft circle but would 3 or 5 be better? I'm just thinking out loud but it feels like a good way to get the most out of my lights. Could someone tell me how fast a light on a rail moves or is it variable. TY.
