The used planting media should not be thrown away because it can still be used for replanting, but of course it needs special treatment to re-fertilize this used planting media. The point is that the first thing to do is to dry it for about one or two days and sprinkle it with carbofuran, this is intended so that the pests in this used media die, then mix raw husks and manure with the same ratio or half manure, after stirring until smooth and pour EM 4 for fermentation like we make new planting media, after one week the planting media is ready to be used again.
