In reply to: Mold on leaf cuttings
If I have mold/mildew on the surface of the mix in a prop box, I just spray it with Neem or a fungicide (I use Immunox because it's easily available and has worked very well for me). That usually takes care of the problem after a few applications.
Opening the prop box and letting some fresh air in every once in a while will also help.
I usually get white and rarely grey mold but have never had green mold. Are you sure it's not just algae? Because if it's just algae, then it's not a problem but just cosmetics. :)
