when my brocille finish ,i plan on fermenting it ,full of calcium for both you and the soil,lol,if you have the em all that left is some wheat bran,i pay 16 bucks for a 50 lb bag of it at feed store,just mix the em1 with the bran until you just get a little moisture threw your fingers when you squeeze your hand and your done,imo you cant use to much just takes a little longer to dry,i mix 10 lbs bran and cant remember the exact amount of em1 i use,get the squeeze right and those contractor thrash bags at the home depot all i use,get as much air out as you can and tie the bag off,put in the dark,i do a 33 gal can,4 bags at 10 lbs each,sit it under a tree and let it go 2 weeks,spread out on a tarp a bag at a time,turn it now and then ,about hour later it dry and stored in the same can i made it in,got to watch the can though,the bags swell but not to the point of exploding,during the day the can lid goes up at night goes down haahah,if you really want to save money buy the mother culture em1,does 20 times what a activated bottle does,im using Pro Bio balanced original mother culture concentrate,i only make a quart at a time,same fermenting process other than you have to check when it ready by ph reading,3.5 and under use it,dont sweat the little white specks floating around ,but ya i ferment just about everything my property provides,cactus and brocille next,im well stocked for the upcoming season,i also use the fpjs em1 bokashi in my medical grows,works really well and less damn headache,confining them girls is a job ,mainly them finecky bitchs,but they mind hahahh
