If I may suggest look into LST (Low Stress Training) it might help with having a even canopy. Also you might also want to check out the SOG method. But the little ones are looking nice but keep them lights close. Now for all those Y spiltters you should stop by ur local walmart and get sockets and cords ($1.98 total for both) then put a Y Spiltter in each socket might help keep lights spread evenly.
