well bugeye, im old school for the most part. the soil i use is plane topsoil and mix coconut soil with it. I have a wood burning stove so i put the top soil in and incinerate everything in it hence "no nute" then i use 5gal. buckets and i leave dirt 3' from top, and drill 1 1/2. holes in around top so air can flow. cut cardboard to cover the top with a slit in it so you can slide it around the stem and paint it white. i only use it in the hottest times of the light cycle. that also helps when you lollipop cause theres not much small stuff to take off. as far as heat idk in the summer i have the same problem. right now im fighting the cold. i cant get my temp. past 76 and im on 24/0. i need to flower so im going to have to run a heater, just dont know that one to get so it dont put off any light to stop the flowing.
