I wrote all that ? Maybe it was because I hadn't smoked yet. Or because I'm nursing seedlings with teen temps outside. Once your plants mature you've gotta have healthy airflow unless you're a fungus farmer. And that air shouldn't be cold, so you have to heat it.
Heat mats also may not be enough during flowering when the growth is at the other end from the roots.
