The Growing Medium collection features the NPG Aroid Formula and NPG Pole Mix — purpose-built substrates developed for aroids and other collector foliage plants. The Aroid Formula is a carefully balanced potting substrate designed for container-grown plants, while the Pole Mix is a dedicated moss pole substrate engineered to support aerial roots, attachment, and vertical growth.

Both mixes are designed to be cost-effective without sacrificing performance, allowing growers at any budget level to use the same professional-grade media used across the Nelson Plant Guy collection.

Why buy from Nelson Plant Guy

The same mixes are used across all price tiers, ensuring consistency from entry-level plants through to high-end collectors’ pieces. Each blend is built for long-term plant health and stability, and developed through real, hands-on growing experience — not theoretical recipes or repackaged materials.
