i am a first timer like many people on the city and have tons of questions but ill jus stick to one. im using rockwool as my medium and there is like a green algea or some kind of discoloration on the cube is this something to worrry about? how do i get rid of it if it is something to worry about?
You using rockwool permenantly or just for seedlings? Thats fine for seedlings, if you're actually growing in them, you need to make sure no lights hit the cube and roots.
the roots asre defenetaly not being touched at all by the light but i def havent kept the rest of the cube away from the light i have the cube place in clay pellets if i cover it better now will the green stuff get worse or will that make it better? is there anthing else i can do? it has a very good root growth out the bottom of the cube any other advice? thanks alot
another question by the way u said that rockwool is fine for seedling but wat options do i have after that? what would i place the small cube in once vegetation startes? again i apppreciate the help
