Does anybody know whats gonna happen if i uncovered them and the sunlight is still more than 14 hours in a day?
I don't know from personal experience, but I've read that some strains can sense that the nights are getting longer each day, and so they stay in flower, even though removing the blackout mechanism means that the plants are exposed to longer days.
I'm at the point where I have two plants in flower now, and I'm wondering when I can stop covering them, and just let the natural daylight take over.
Thankfully, I can go on black-boxing the plants as long as I need to, but I too wonder whether it is necessary.
