I have a closet grow and it is getting cold at night with the light off. I raise it on colder days with the incandescent bulb in the ceiling fixture. Keeps it warm. I use 20/4 lighting so if I leave that incandescent bulb in there on as light, Wich isn't much honestly, will it disturb the plants' "sleep period"? I'm sure it would mess with a photos flower, I'm not concerned with that, just with the co2 transfer they do while "sleeping". Thanks.
