ok this is all new to me, so is the key warm and dark or light and warm, I live in michigan and its just starting to get around 40 and I have to do my wineing in the pole barn I built a box with a lid and insulated it the easiest way to heat it is with light bulbs inside the box I plan on putting a thermostat inside to control the heat, but is the light from the bulbs going to hurt, also can I do it in the fridge sorry for the lack of terms but I dont know I havent bottled yet
