well the easiest way is to do one of two things i think. one is to buy a KIS organics re amendment pack and make that with your used soil and stuff. 50 and free shipping. not terrible.Makes 30-40 gallons depending. or buy bags of KIS soil,tlosoils.com soil amendment pack works as well.yet not quite as potent since the fish compost and things,but again,works nicely.or you could also buy a bag of soil.say Dr earth,roots any of those and add some Lime,compost materials like bokashi,steer and/or cow compost with a cup or so of mushroom compost and then add your more potent granules. the last is probably the cheapest but the KIS pack is your best bet imho. yet you do have to wait 2-4 weeks between granules,KIS packs and the cooking or even the 2 weeks for blending of the granules. so there are options man. just gotta figure out which one suits you mang.
