You can throw whatever you want to top dress with for next grow in the bokashi buckets too. I like some rice hulls and hoarse tail,azomite, aloe powder, dryed herbs of many kinds , alfalfa,fozilized bat guano. The lactic acid bacteria will chew it up for the plants before hand like a mother bird feeding a baby. I will try to throw up a recipe of what I used to build my top soil (o horizon) if I can find the recipe.just give everything something to do,the microbes and bugs want to stay busy.its crazy how much stuff I put in the 30 gallons and they stay the same height. I guese allot of it is stuck to my lungs.coming to Thai land mabey next year. are you thier?mabey trade some genetics.
