Well the environment should be good. Humid, moist dipped cuts, warm, rooting gels help. Look into rapid rooters, they are made with natural materials that promote rooting. Keep the moisture fairly high. The bottoms of the rapid rooters should stay wet, the rooters will only hold in the moisture it needs to.
- Also, I've noticed better results from giving them about 6 hours of dark right after cutting and putting them in plugs...
so you might want to take your cuttings right before lights turn off for the night (supposing you are on 18/6). Good luck bud.
