I have been using rockwool for two years now for my clippings.
My problems with using rockwool is that the cubes dry out quickly requireing ongoing watering and it has been taking two weeks or more for roots to show.
Temps are in the high 70's to low 80's and humidity is fine.
They sit under T5's in their dome for three days and the dome is removed and they get misting every second day.
My question is this....
What do you use and what sort of results do you get?
Suggestions, and thoughts welcome.
