Hello everyone.... I've been recycling my indoor soil for years - mostly because I'm frugal. In my garage, I keep a 30 gallon trash barrel, where all my left over (indoor/used) soil goes. I throw in a few handfuls of greensand, bone meal, two cups (each) of High N & High P Bat Guanos and let it cook. I also add a gallon of mixed up - Super Plant Tonic solution, which is full of beneficial bacteria & myco fungi. Once every two weeks, I stir it about, but otherwise leave it alone. Two months later...... I mix it with compost from my backyard compost barrel, some coco fiber (well rinsed) and worm castings from my worm bin. Compost 50 percent, Recycled Soil 30 percent, Coco Fiber 10 percent, Worm Castings 10 percent. Mary loves recycled soil, I do too - it saves money and it just keeps getting better over time. Since, greensand and other slow release amendments take time to release all their goodness. Reusing it, works well...

The key to making it really work - time. If you let it cure for two months (min) - Mary loves it and it does not burn......
