I’m no expert but I accidentally screwed up some clones by putting them outside without weening them off artificial light hours. I believe if you lower the light cycle by 15 mins every few days until you reach outside light hours they will be fine.
Holy sunlight, Batman! Where do you get 16 hours of sun? We only get up to like 14 and change in Southern Cali. I get mine started by 13 hrs outdoors here.
