are you talking regular potting soil or SuperSoil as outlined in Subcool's recipe? If reusing SuperSoil and you throw it in your garden that has other veggies then it may f*** them up. Sub said he's found recycled SuperSoil to be good with tomatoes and raspberries, lettuce will die things of that nature. But this is only for supersoil, figured I'd add this info in here in case a newer person stumbled upon this thread in Sub's sub-forum and thought original poster meant supersoil.
