Warm water? Thatâ??s good if you want to eat your plants or make tea. First you really just take the cutting then you cut the angle when the clone is away from the plant. Make sure you soak the Rockwool the day before in Ph 5.2 water for a full 24 hours before you use it. That may help stabilize the Ph of the Rockwool. (that what the makes sayâ??s, lol)

You should root the clone before you try to use grow rocks. What about anit-wilt? Or are you going to use a humidity dome? What light are you using again for cloning?
