Squirting I just had 100% success rate on the method I just mentioned. No humidity dome.
4 bar t8 cool white
Rooting powder
9 styrafoam cups
Promix bx
Regular tap water
I poke holes in cups for drainage, put in promix, soak the promix with water till drained, put hole in middle of promix, sprinkle rooting powder in hole on sides of hole if u can, cut off clones put in water dip in powder, then put in hole and compact dirt around clone, put as close as possible to light, keep watered don't let soil dry out, within 10 days you will have roots. ..
Sorry for the run on sentence but that's how it gets done in the capital....
