NOTE: 6tsp per gallon is an estimate since there is not an option for tablets/gallon of soil. I use the fertilizer tablets exactly as instructed by the company. 1 tablet per gallon of soil. Soil is happy frog mixed with oregonismxl, worm castings, bu's biodynamic compost (malibu compost), and bokashi (.25lb/gal of soil). I also try to keep the soil as undisturbed as possible, while not quite replicating a no-till garden, I get as close as possible to give the beneficial bacteria/fungi the absolute best chance of survival.
