HELP! Moss growth on rockwool cubes...


Recommended Posts

I don't know whether this is bad or not but this morning I looked at the plants and there is dark green moss/algae growing on top of the cubes.

They were due to be placed into the main growing pots today but I am not sure if I should?

I scraped the moss off the top as well as I could without disturbing the roots/plant - does anyone know what the go is???

I think I found my answer in the forums...

 

At the moment without seeing the pot i would suggest that it could be green algae which is basically harmless.

One way to get rid of algae is to deprive it of light, which it needs to photosynthesize. The method is very safe because it involves no chemicals. You can affix black polyethylene plastic collars around the plant stems that cover the tops of the rockwool cubes. Other materials that can be used are white cardboard or styrofoam. If collars are inconvenient, then strips can be placed over the tops of the pots to cover them.

Hydrogen peroxide can be added to the water and will deter growth of algae, but it may also affect fertilizer chemistry.

Personally if it is algae and the plant is healthy i would leave it alone.

 

Hopefully this is what it is - I can't take a pic as the batteries are dead and it's Good Friday....

 

Any other suggestions welcome though.

yeah nothing to worry about as long as your res is lightproof, although I can't stand looking at the green gunk either. When you move them into the hydroton you can place some smaller clay balls on the cubes to block the light, it won't worry the stems, or do as suggested in that post you found and make some little collars out of black plastic. Either way it shouldn't worry
