friends' fursuit โ๏ธ๐งตeverything toy's learned thus far about an alternative terrarium substrate mix. Not the usual layered method with drainage, filtration, & soil. This mix has ideas from semi-hydroponics & planted aquariums. Springtails can also be added later as needed for cleanup.
by combining all the necessary substrate layer functions, maintenance becomes "simpler" & the setup looks cleaner. Its proposed approximate recipe is 2 parts inactive : 1 part charcoal : 1 part aquasoil, with all parts measuring granules around 3mm, just avoid a completely sandy mixture.

Michikusa uses another ratio of roughly 2 parts akadama : 1 part fuji sand : 1 part charcoal. This seems to work well too, so the aquasoil could be entirely unnecessary for moss & certain plants...

with both recipes, it's fine to mix in an extra part of an inactive ingredient. Michikusa does that for certain builds to add color and those terrariums are probably dandy
