Why is my grodan turning dark greenish? Is that okay???
Whats a grodan?
Algae - you need to cover the top of the cube with a grow medium like hydroton, or you can use cube covers. No light getting to the cube, will kill off the aglae.
How do I cover it?
For this my man we need a scientist!!!!
Cut up some mylar....or a space blanket....hell use foil, if you have to
Than i'd have no lighttoit?
You cover the top of the cube, not the plant
