    Green is algae and grows with moisture and light.Keep them covered to stop light or get algaecide for aquariums if it bothers you that much.

    I also have green algae on one of my peat pellet clones. Is this something i should be worried about? Or is it ok?

    I only use Rockwool. You can prevent algea from growing by covering them with a white block cover. sold at hydro shops.

    ^ get the covers for sure 10$ for 40 of them and they are re-usable. I only use rockwool even make my own seed pods and I almost never have any issues . And if your watering them to the point its building algae your probally watering to often
