Hey all, just started my first grow a couple weeks ago. I have a small 2x2 tent with a MarsHydro TS1000 light. I am just growing a single auto (GSC) plant. Currently I have the light set @25% and it is about 6" above the top of the plant. Just curious when I need to increase intensity and height. What general rule should I be following to make sure she is getting enough light throughout the 18/6 cycle?
