78,600 lumens at canopy, ok for pre-flower and flowering?
I have recently received a lumen meter. Measuring 78,600 lumen over canopy, is that OK? For my other grow, does anyone know how many lumens seedlings need (at about 25000 now) ? I can convert from PPFD or PAR. Educate me! Thanks

Worths investing?
Thinking to upgrade my grow with 4 x 15w led bars. 1 on each corner of the grow room, vertically, as secondary lighting to a 400w hps. Does it worth the investment? Price vs yield?

Can I switch my lighting schedule ?
Hello everyone. 1st grow here. I'd like to swap my lighting (automatic plants) from [4am:midnight] to [4pm:noon] just to keep the temperature a little higher at night. Is it doable while not hurting the ladies or should I shift it an hour per day to change the cycle ? Thanks !
