Fellow farmers often refer to the formula as 'subcool's super soil'. (there are threads here)
The idea is to provide a dirt/microbial environment that needs only water additions for the plant to go from start to finish in a small pot. (I use 3 gallon fabric bags)
I also am using alfalfa tea.
It works!
Good water, microbial tea, and light. That's it.
I have only been growing for two years, but my confidence is high as baring pests or wacko experiments, I can trust that my plants will perform as designed.
The stuff list: (12 cubic feed)
Ten buckets of peat (local bog product sold by the pickup load)
1 bag earth worm castings
1 3 foot bag compost
1 box blood meal
1 box bone meal
I also add a box of high P bat guano and have stopped adding any perlite.
It all seems to be about providing a good microbial medium in which your plants roots negotiate a living.
I will admit that this method limits my ability to 'dial in' a regimen.
My Grapefruit x Blueberry has a habit of starting to strip large fan leaves of nutrients starting half way through flower, while my White Fire loves it start to finish.
I don't understand this, but the buds are big and solid, so it is more of a curiosity than anything.
The list of additional items that some add to their soil can get very long, as most people feel that more is better. I am resisting this inclination and keeping it a simple as I can.
Good growing.
