Premium Planet Earth Horticultural Perlite – Ultra-Lightweight Soil Additive

Boost Growth | Superior Drainage | Professional Grade

Are your plants struggling with yellowing leaves or slow growth? The culprit is often "wet feet" caused by compacted soil. Planet Earth Perlite is the ultimate solution for gardeners seeking professional-level results at home — 100% natural, expanded volcanic glass that creates the perfect balance of oxygen and moisture, ensuring your plants never suffocate.

The Classic Seed-Starting & Cutting Pairing

Perlite's signature use is mixing it with vermiculite to create a cheap, effective seedling and cutting medium — vermiculite holds moisture close to fragile new roots, while perlite keeps the mix from ever compacting or waterlogging. If you're starting seeds or striking cuttings on a budget, this classic 50/50 combination is hard to beat.

Why Choose Planet Earth Perlite?

Prevent Root Rot: Dramatically improves drainage so excess water flows through, preventing the fungal issues that kill most houseplants.
Maximum Aeration: Provides essential oxygen to the root zone, leading to faster growth and thicker stems.
Sterile & Safe: Heat-treated to be free of weeds, pests, and diseases. 100% non-toxic and safe for organic vegetable gardening.
pH Neutral: Won't mess with your nutrient schedule or soil acidity.
Resists Compaction: Unlike organic matter, perlite doesn't break down. It keeps your soil fluffy and aerated for years.

Perfect For:

Seed Starting & Cuttings: Paired with vermiculite, high porosity encourages rapid, even root development in clones and seedlings.
Indoor Houseplants: A must-have for Monstera, Philodendron, and other Aroids.
Succulents & Cacti: Mix with compost to create a gritty, fast-draining desert mix.
Hydroponics: Use as a standalone medium or a component in Dutch bucket systems.
