Mold on cuttings - bottle method
I have cuttings planted inside in a potting mix under lights on a timer. They are covered by a plastic bottle. I have only watered them once last week and let the condensation do the rest, then watered them again a couple of days ago.
Noticed mold on one. Should I remove the plastic, or spray it with something (do not want to use anyt pesticides) or throw it away and hope it does not spread to the others?
