I am planning on growing in soil and indoors and its going to start getting cold soon. Temps will range from 65 during the day and like 40's or 50's at night. I am wondering if i need to heat my grow room at night when the lights are off. Or should i just run the lights during the night and leave em off during the day.
If you can flip the lights. Flip them otherwise add a small heater with a temp gauge. Easier to just flip the light schedule though
Flip the lights its a win win situation. If not I wouldnt go under 60 F lights OFF. If you can stick to a permanent 76 F your golden. If your using CO2 at the beginning meaning 50 minutes before and after sunrise, closing the carbon filter, let the temperatures rise to 86 F and 80% humidity. Then you can lower it back to 76 F and 30% humidity
