In this episode of BuildASoil, Jeremy is discussing ideal moisture content…
…and near the end he suggests searching the web for these charts…
…where I found links to this nursery operator in southern California who has some videos & a website…
…
It’s really controversial to the past 5 years of living soil nerdery that I’ve been engaged in 
but the science & explanations seem solid.
If he would just enter the Emerald 
Cup & take top place as a first time grower, I’d drop everything & switch methods. 
Cannabis growers have been mostly excluded from decades of progress in plant science but hope that changes.
Am very interested in what everyone thinks.

There’s a guy featured on a bunch of Future Cannabis Project videos(name escapes me atm) who describes a “horizon” layering of rock then sand then clay then humus then mulch … which is similar to nature. (More so than just a pot with some mix).
The mixes this Gary dude uses are on his site … iirc, a 1:1 peat pumice, a 60:30:10 pumice peat sand, & then pure sand for any pots over 12” deep…watering daily.
The daily watering is fine for a nursery but that’s laborious by hand, & kinda inefficient maybe expensive.
It’s hard to picture a healthy mycorrhizal situation in pure sand with granular organic fertilizer.(I.e trees in larger pots of sand). Wtf carbon source do they have?
If he could do a chat with Elaine ingham or Buildasoil or any reputable dope grower 
I’d be more convinced.
