Thanks bro. 4 would be ideal I think. I wasn't sure If I could SCROG autos...now I think yes.They'll definitely throw on some weight in the next coming weeks..Maybe not as substantial as those main colas but definitely not a loss either. .A scrog with about 2 plants less would of gave a nice uniform field of colas where you could drop that light down and really dig into that canopy, but you have a jungle in there this run and they look real good, nice job. That light kicks ass from what I can see.
This is my second grow with this Sun Systems 315W LEC and I'm sold. I keep the light 20-24"'above.
