Heh- I thought the endo class was limited to glomus, non-inclusively.

OP- GH's logic in replacing culture w/ res change is that there are interactions between micro-organisms that can influence plant growth/health, beyond any primary affect each organism may have. You're resetting your population ratios w/ reapplication.

See incredibly long pdf file here I think that you'll need to click the manual download link.

On the flip side, endo populations in particular tend to perpetuate.

I couldn't speak for population ratios in the final product, but you can grow out Subculture at home- Room temp water (gassed out), 5% grow nute, a little bit of glucose ( or whatever ya got handy), toss in a pinch of Sub, leave it in the dark a couple days- It'll breed.

Yer on yer own for dosage.

Do not kick over- stinks pretty good.
