After see this weeks article on reptile heating mats, it got me thinking about root zone temperatures again. I've had years of successful grows but always looking to improve. My grow room is in the basement with a concrete floor. I always keep air ports raise off floor but have wondered if root zone is still a little cool for optimal growth, especially with air intake blowing across damp air pots. Have thought about using reptile heating pad to help keep root zone warmer but just haven't pulled the trigger. What do you guys think?
