when i was younger we use to get this stuff called Grit from the local sewage treatment plant it looked like really thick black oil it had no smell and from the way i understood it , it was all the stuff the comes from garbage disposals, i was wondering if anyone had ever heard or tried any of it, we use to go get 5 gallon jugs of this stuff and you talk about making plants grow OMG i swear i have seen tomato plants grow over 8 inches in a 24 hour period after it was applied , we use to make little levees around the plants and just pour it on it took a good two hours for it to seep into the soil and it was perfectly harmless to humans , my uncle was the Boss over this plant and he used it on everything ... i was just wondering if anyone ever heard or used it ..
