We've had some bad weather lately, with cold temperatures and rain. I live in an old house, so the indoor climate is very much linked to the outdoor climate. The rain pushed up the humidity in the tent, making it difficult to maintain VPD.
On the other hand, the cooler temperatures brought out the color in the leaves, and now there are some lovely splashes of purple in the tent.
So that's nice. Besides, I'm not worried about high humidity this early in flower.
DLI: 40
UV: 2 hours per day
@Still_Smoq, Thank you :) I travel frequently, so I need a system that cares for the girls while I'm gone. The last piece of the puzzle I need is a camera to remotely monitor them.
@StarLorr, Right?! So pretty. No clue if it is due to the low temps or the UV. I suspect the UV more than the temps, to be honest. The mom plant experienced lower temps and never turned purple.
