Green light during the dark period

[TMusic]

What's the verdict on the green light during the dark period. I need to do some ph adjusting during the dark period but I don't want to interrupt the dark.

with a green light you should be fine. I would suggest that you dont leave it on for too long though. :D

One late night of tinkering when the lights are supposed to be off will not harm anything. It takes more than that for plants' cycles to get screwed up. I have done it many times and have never had a hermie or other related problem.
