PLANT!T Perlite 10L — 2-4mm Horticultural Grade

PLANT!T Perlite 10L — 2-4mm Sterile Horticultural Grade

A smaller 10L bag of PLANT!T's sterile horticultural perlite — the right size for a single medium grow bed or multiple pot amendments. Natural pH-neutral sterile volcanic rock, providing the ideal air-to-water ratio for faster germination and cutting strike. Mix at 20-30% into soil or coco to transform how your medium performs.

Why growers add perlite to their mix:

• Improves aeration around roots — plants get more oxygen, grow faster
• Dramatically improves drainage — excess water escapes rather than drowning roots
• pH-neutral and sterile — no pH impact, no introduced pathogens
• Faster germination and cutting strike — air-to-water ratio optimised for young plant development
• Derived from volcanic rock — natural product, heated and popped into lightweight granules
• 2-4mm grade — standard horticultural size, right balance between water retention and drainage
• 10L size — right for amending a 50L coco bag or mixing multiple small pots

Who it's not for:

For larger batches (multiple grow beds, repeat use), the Eden Essentials 100L bag is much better value per litre. Dust mask recommended when handling — perlite dust is harmless but irritates airways. Not needed in pure hydroponic systems (DWC, NFT, clay pebbles) — perlite is a soil/coco amendment.
