Aqueminianswered grow question 2 years ago Don’t worry about it to much. My rapid rooters will get green algae from keeping them to moist. You can cover them so light doesn’t hit them, or just let them dry out more. They just need to be slightly damp. I use to over water them, now I know I can apply a few drops of water daily or twice a day until roots break the net pot then I let them dry out completely.
