green from my rooter plug ?

started to see a couple of green spots on the plug once the seed popped off even before i plant it in soil and now it's spreading. anyone got a clue what it might be ?

Ease back on the watering....

ALGAE

Yep common wen people pour water on the CUBE!
Why my hydro top feeder is a waste of time.
Just cover it with some soil. It'll go black when it drys out.

In future , water around the earth, not the rockwool, or use jiffy pellets instead if you don't like the algae.

I agree too much water. Also I try to cover the rapid rooter with soil so that doesn't happen. Algee needs light to grow.

Never had this problem, but curious - does it just grow on cube because that stays moist / holds water longer, and gets the time to grow out? Or is there another reason that the rockwool grows it? I used rapid rooters my first time, but hydro store only had rockwool last time, so been using them. Just curious why the rockwool grows it but not the others. Thanks!

And good luck, OP!

Wait... or is that even a rockwool cube?
