Ok im confused with the 12" height,if i put my light that close im pumping out 90000-100000 lums so my 3 light apps tell me on my phone.I read post about other people with 400s and you get so many different answers from 6' to 3ft.You have people say do the hand test and i do but still way to high on the lums and im going by what all the experts say the lums should be for each stage of plant.My plants are 24days old and lowered my light 4days ago at a height where im getting about 37000 lux and saw a big improvement.How many of you are doing 12inches and at what stage did you lower it to that
