Laboratory-screened, peat-free structural substrate formulated for hemiepiphytic aroids, Anthuriums, and terrestrial orchids requiring rapid gas exchange at the rhizosphere.

Formulated without sphagnum peat bog extraction, our 8–16 mm screened substrate maintains 38% air-filled porosity after saturation, eliminating anaerobic root decay in aroids and epiphytes.

ON THE RECORD

Pet-safety notes in the Atlas cite the ASPCA classification recorded for each species. Where no classification has been verified, the record says so.
