Green Mildew, Mold, or Fungus or something

So i was checking out my plants today and the top part of the soil seems to be green.. it could be fungus or mold or something... what's causing it and how can i stop it.. livin' in orange county socal so ya pretty damn hot...

We need pics man. But just scoop it out and replace it. quick.

And yeah damn OC heat! Flowering chamber ranges from 95-80 deg F!

i have a feeling its moss, i did remove it and put more potting soil on top... but ya lets see what happens

That green stuff is no big deal, but it will eat up your nuts. I used to always get that on the top of my grow medium also. I now place these Panda Covers around my plants, It keep the light off of the grow medium. This will stopp this alge, or mold growth. I think it is Algae. If you are useing soil, you might be keeping it a little to moist.

can mold or fungus be green?

Of course it can be green.

Ever heard of a green Moldy Sandwich?
