With winter arriving quickly to my northern area, I am presented with a small dillema. My small grow area has worked fine for my first grow. Its a box 6ft across, 6 and 1/2ft tall and 4 ft deep and handles 6 plants quite handily. The problem I face is that all of this goes on in an unheated garage. I have gotten a base board heater to wire into the grow area and will have it on a thermostat. What temperature do I need to keep the thermostat at? Is all of this dry air going effect my growing routine, if so, how?
