This product is an essential soil amendment. Basically, it's like ground up brick. The product is fired at 1,200 or so degrees and becomes "rock" hard. Years from now it will be the same stuff in your potting medium as it was when you put it in there. It is used in lieu of sand because most of us cannot obtain the correct sizing of sands as most are usually too fine, being more like sugar or salt granules. Do not confuse this will cat litter which will break down into mush in contact with continuous moisture. |
