I have about 3 times as much soil as I use at any time in a grow. So i rotate it all. Every batch of soil gets a little over 4 months rest. After harvest I let the pots st for 2 weeks to dry out a bit. I pull the stump and the big roots that come with it out. all those little roots don't cause problems. they can hardly be found by the time the soils ready to be used again. I stor the soil in these 100 gallon totes I found at walmart. Because that's about how much I have in use at one time. I add in some mycos and a bag of organic tomato pellets that I pick up at the farm store. I think the npk is 4-7-6 on those they are made of bone meal, blood meal, alfalfa, kelp, fish meal, and feather litter. I water it in so that it's all wet but not logged and put the lid on for 4 months. set it and forget it. oh and lol the fertilizer I add has 7% calcium already. I use fish emulsion to bump up the nitrogen and I'll foliar feed kelp and fish emulsion once or twice a week until bout the 3rd week of flower. then kelp until about the 5th week of flower.. No muh budz don't smell like a pond they are the loudest around. smell like blueberry muffins and oranges. Just last week i went to my buddies house and the second I cracked the jar people 20 feet away were commenting that that's the weed they want lol.
