About this item
- 🌿 MAXIMUM ROOT RESPIRATION | Roots are lungs; if they can't breathe, they rot. Our P35 Coarse Perlite is a volcanic-grade mineral grit engineered to create permanent oxygen pockets within your substrate. This "Gas-Exchange" architecture fuels faster metabolic growth and ensures your root system stays aerobic and resilient.
- 🌿 RAPID DRAINAGE INFRASTRUCTURE | Built for the "Flash-Flood" watering cycle. This coarse mineral amendment allows water to surge through the pot and drain instantly, shedding excess moisture before it can stagnate. It is the professional tool for eliminating the "swamp effect" that kills 90% of indoor tropicals.
- 🌿 ANTI-COMPACTION VOLCANIC GRIT | Standard potting soils collapse into an airless, suffocating brick over time. P35 is a structural aerator; it provides a rigid, non-collapsing scaffold that maintains its physical geometry indefinitely. It ensures your mix stays "High-Flow" and breathable for the life of the plant.
- 🌿 100% STERILE & INERT | No mystery fillers. No pathogens. No industrial waste. This is kiln-expanded volcanic glass, 100% pH-neutral and chemically stable. It won't interfere with your nutrient schedule or rot over time, providing a clean, honest foundation for your most prized botanical specimens.
- 🌿 PROFESSIONAL GRADE AMENDMENT | Hand-packed in the UK for the serious maker. Whether you are amending a custom coco blend or building a high-drainage orchid mix, P35 provides the structural integrity that retail "fine" perlite lacks. A clinical, high-performance tool for the modern indoor jungle.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
