Hey HB
In regards to your vape pen, do you ever try different kind of coils? I've been using a vape for nic for about 3 years now. I've made about 1k coils in that time, became a hobby for a while. I'm not really sure what kind of heat is needed for extracts, but if I had to guess, your coils are at about ~.8- 1.1Ω for roughly 17.5-22 watts on a full charge. Assuming its 20-22g wire at a 7/8 wrap, and based on a pic (i could be totally wrong just guessing)....It also looks like you have a 22mm piece. Is it a mechanical, or a regulated mod? Personally I prefer a big ass single macro coil. Normally around 1-1.5Ω with 22 or 24 gague wire set at 40 watts or about 5-6volts. A good youtuber for wire guides is riptrippers, hes also on instagram. Look for 1 called the Clapton coil. It was a hell of a challenge, and a waste imo, but fun to make. Anywho, have a good one.
Heady man I don't think we talked about what you use as a hormone for rooting if any?
