Will this affect my dark cycle??

I just switched my lights to 12/12 and it dawned on me that in my grow room (3x4x i have my continuous water meter,chiller and dehumidifier which all emitt a little bright ass light.Will that interfere with my flowering cycle?????Thanx

I would put a piece of duct tape over the light node. My heater did the same thing and I just covered it for precautions.

Boneman is right, tape over the lights good. Hemies suck...lol

Thanx guys.could that little bit of light be enough to make a hermie??Does the color of the light matter???Can u really use a green light during the night cycle if you need to look at your girls without interfearing with the light cycle itself???
