My question, too! In my bud chamber (basement boiler room) "fire light" is visible each time my boiler's burners ignite.Does light given off by a fire affect your plants duing the night cycle? Late in flowering also
The burners light intermittently but frequently all day and night during the heating season, here!It depends on the size of the fire and how often it is happening. If its happening every night there is a definite chance it could affect your plants. If its just one night, I wouldnt worry too much
