When I first bought my SF1000s I started at about 40% and a few days later 1 of my 4 seedlings bent over. I propped it up with a stick and a day later it was bending over again. It was trying to get away from the light. I turned the light down to about 30 % and slowly cranked it up over the course of a week to 50 %. Another 2 weeks and I slowly worked it up to 75%. Only the 1 of 4 seemed to have any problems the rest didn’t seem to care one way or the other. By the time they were 6 weeks old I was blasting away at full power.
