What Is a "Chunky" or "Gritty" Mix?
A coarse growing medium made up largely of inorganic materials that more closely mimics the natural environment that many popular plants like aroids, tropicals, cacti, succulents, or orchids come from.
There are a number of benefits to a chunky mix that make it superior to any standard "specialty" tropical, cactus, or succulent soil you'll find in big-box, or even high-end plant shops.
- The extra aeration allows the roots ample room to breathe (Oxygen in + CO2 out) and avoid shrinking, caking, and compaction.
- Quick draining means water is able to freely penetrate the soil to get to the plant's roots and drain excess through the bottom of the container, avoiding the dreaded "wet feet" that leads to root rot.
- The mix still stores water well, but allows for the substrate to breathe and dry in a more consistent manner. The moisture it does hold is retained in the components and kept off the roots, unlike the wet, muddy consistency of peat-based potting mixes.
