Spraying the cutting itself before it roots eliminates the need for root growth.You can use the B-1 green after rooting but I never spray the cuttings directly.Just the dome.The plant has to need H2O to start rooting.Humidity keeps tissue damage to a minimum.Every day let it breathe,increase the amount of no dome every day,if they start to wilt spray the dome and put it back on.I have seen so many people especially myself ,fuck with a batch of cuttings til they die.Check temps and patience grasshopper.PEACE
