I mix Forest Floor with Retibark. Sometimes I will also add EcoEarth depending on how I'm feeling and the look I'm going for.

I have a large tub I poor them into and mix. Then I use it out of there as needed. The tub is a snake tube so the lid had holes so the damp Forest Floor doesn't create and issues with mold. If does dry out but I just add water and stir the next time I need it.
