I live the northern US and in the winter it gets COLD (average about 15 Fahrenheit). My grow space in an uninsulated attic and I want to make a growbox to winter over my mother in. How much and what kind of insulation will I need? I was thinking the pink hard foam, 2 inches thick, with air taken in from my room which is about 70 degrees.
Advice?
