So about a week into my grow i noticed at first that the to of my growing medium had this green discoloration, then a few days later i noticed that the runoff water was turning green too. i noticed on the package for my sunleaves coconut hulls starter plugs that they say they may encourage mold growth that is harmless to plants.

So do you guys think its mold? Well is this mold really harmless? What can i do about it? Any answers would be greatly appreciated, thanks.

Hello elmim1,

From the sound of your desciption I believe you have algea growing or possibly (remote) a moss, and not mold. Most molds are white, some brownish.

Not sure how harmfull it is, but since this is outdoors and I assume water/fed to waste it won't at least clog up plumbing, pumps or a rez.

Are these plants in the ground or in containers?
One possible solution would be to mix a mild solution of FOOD GRADE hydrogenperoxide and water, then spray that on your grow medium.

Maybe someone else that's seen green where it didn't belong can chime in.
Good luck.:)

they are in pots (well cups for now) on my balcony, and yes draining to waste. Where can i get food grade peroxide?
Any help is greatly appreciated because this is my strongest growing plant.
