Aroid Substrate Set – separate components for chunky aroid mixesAroid Substrate Set is made for custom mixing rather than one fixed recipe. That matters because a small Epipremnum cutting, a mature Monstera and a velvet Philodendron do not need the same exact texture.More to know Coco coir: forms the moisture-holding base Perlite: keeps the blend lighter after watering Pine bark: creates larger air pockets for thicker roots Lava Rock Granules: give mineral weight and longer-lasting structure Material and finishStart with coco coir as the base, then work in perlite, pine bark and Lava Rock Granules until the mix feels springy and open. The finished substrate should hold some moisture while still falling apart easily between the fingers.DetailsVery small plants, fresh cuttings and fine-rooted tropical species may need less bark at first. Potting too chunky can reduce root contact, especially in tiny pots.How to use itThis set is meant to make mixing easier. Use it as a full recipe or as a starting point you can adjust with extra mineral or organic components.If you repot multiple plants, mix small batches first so you can tune the texture and drying rate to each pot and root system.Worth noting Pre-moisten dry components for a more even blend. Keep leftovers sealed and dry between uses. Match chunk size to pot size: smaller pots need finer structure.
