CORE - Signature Indoor Substrate Blend (Standard 5L)
CORE
Signature Indoor Blend
A balanced indoor substrate designed to support healthy roots across a wide range of houseplants.
CORE is Harbour & Stem’s foundational blend — created for everyday indoor growing with an emphasis on airflow, structure, and long-term root health. Blended in small batches using premium components, this mix provides the balance many tropical houseplants naturally prefer indoors.
Designed to sit between overly dense potting soil and highly specialized chunky mixes, CORE offers a forgiving, breathable environment that supports consistent growth without sacrificing aeration.
