Sup guys and girls,
I have a situation once again! I have 1 NL flowering right now week 6 and im leanin towards LR2 as my next grow due to my constraints and need for budda O_O. My Q's are
1. If i throw my LR'S in there with my NL for 2-3 weeks do u think i could get away with letting them grow 12/12 for that period? Then once the NL's done i can switch it to 20/4. Would this stress the plants or cause reduced yield?

Yes that will be fine, it will increase yield not decrease it
