A little column a and a little column b.. Some use the soil immediatly, some use it after its sat and the root ball has started to break down. Some people use well maintained raised beds that have a continual soil food web that is maintianed. Ive preached for years about aerated teas, its applications like this that they really come in handy. Taking care of the soil food web creates amazing plants, if you used an all organic grow, stopped feeding toeards the end, your soil shouldnt be hot. I re use all my soil in my yard for gardening, however i dont see why you cant grow another crop on it. Just make sure all is clean, and let it sit for a couple week, watered, just to be safe.
