Where do you have water coming out? When you mix your soil and wet it down it should be in a container that can hold the liquid until it is all absorbed. Sent from somewhere over there. No, not there...over THERE.
If you have runoff its too wet. Let it dry till its just moist like a wrung out sponge. Twas Ever Thus!
I only let it run off once then i let it dry. It's usually pretty dark and never clear too so i'm guessing that's the natural chemicals doing there work who knows. I'll try and keep from any runoff then?
