hey this is my first time growing and I am going to grow in my attic for security and space reasons. I have a grow box up there about 2.5 feet wide 5 feet long and 4 feet tall. I am going to use cfl lights and I need to figure out how to maintain a healthy temperature up there for my 2 week old seedlings. It is currently winter here so if anyone has any sort of solution for me I would realy appreciate it.
