Get a good mix of soil. Meaning an amount of water absorption, compost/dirt material, and drainage.
So like earthworm castings/vermicompost, with vermiculite or perlite, and coco coir or peat moss.
Then start brewing microbes teas. Just compost/castings with molasses. Bubble for 24-48 hours and water as usual.
The more microbe teas you do, the more you are boosting the microbe colony. There is obviously a point where teas don't add more microbes, because your soil is already efficient in with the colony it has.
At this point, just water will be sufficient. The water will keep the soil moist, allowing the microbes a suitable environment to live and do there thing, allowing them to take of your soil, in return providing the soil with a plentiful of pure organic nutrients that will give you many, many, many, harvest.
I think that's all right. I've had a few so forgive me for any mistakes.
