Bill you will be fine. You can use a green bulb not a green filter but a green colored bulb. You will be able to see to work but the plant will not be affected by the green light.

The plant does not see the color green. There are so many other things that affect the plant (heat, Ph, nutrients, ect) don't sweat the little light too much.
Zandor Reviewed by Zandor on . Light during 12/12 dark period, how bad is that? Mostly just curious how much of an effect does light during their dark period have on your plants? Like I don't think a little light now and then will hurt but what if you spent like three or four hours withj the lights on when it was supposed to be dark time?? Also wonder what happens if you change light and dark schedule ? Like going from say 8pm to 8 am with lights out then after a couple weeks changing it to like something like midnight to noon with lights out ? How important is keeping Rating: 5
