this is what i do after the block has soaked and expanded: i just break the substrate apart and ring out the excess water, put it into a separate container, and leave it in the sun. or you can do it the quick way by oven drying it.Where do you leave it out to dry in the sun? Im worried that if I just lay it on my deck or cement ants will get into it (and that's bad, right?). Maybe Im doing something wrong because this stuff seems to take forever to dry out.
