I use perlite in my super soil but I'm to try living soil this year. The goal is to use nothing except what is produced on the farm. Most of the outdoor is ready to plant. Grow room, almost.
Anyhow I don't want to get of track from the OP's thread.
best results i've ever gotten is ironically one of the simplest grows i've done.
leaves, grass clippings, and steer manure for the compost ingredients.
compost those three together and the results are not only very impressive but virtually no care is needed past watering the mix once transplanted.
the key is to make sure there is plenty of carbon in the compost (leaves/wood chips) the more carbon inputs you have, the more spongy type humus the compost will make, the more nitrogen inputs (grass, manure, fruits, food scrap) the more nutrients will be available but at the detriment of drainage, mushy more clay-like compost (vermicompost also)
keeping in mind the top two biggest mistakes people make are over watering and over feeding.
which brings me back to the carbon inputs, that spongy humus works as a buffer for the nutrients in making it not avail all at once, also while working as a sort of "aeration" allowing the mix to drain, what you do NOT want is too much nitrogen inputs in the compost which makes the soil retain more water, typically locking out calcium and magnesium due to the acidity of the wet mix. The carbon-based humus is loaded with microbiodiversity as well, so the nutrients are buffered as they are consumed over and over making them avail for your plant as it needs it.
Biochar is a great additive for these mixes also, anything that is composted with nutrient heavy ingredients should have about a 10-15% mix of charged biochar
buy a bag of cowboy charcoal, crush it into bits, throw it in a tea with a nitrogen input such as manure, bat guano, fish meal (stinky tea though)
i do NOT recommend blood meal, for anything really
