I have a quick question for experienced growers who do a lot of dark time activity w/ their plants.

I was wondering which color spectrum will *NOT* disturb my plants darktime hours if I were to need to go in and say change my bulb from Mh to Hps? or any other activity done during lights out?

I was told that "green" is the only color spectrum that wont disturb the Photo Period.

I need your expert and experienced input?

Thanx,
