Perlite

Premium Grade. Average Size 4-8mm.

Perlite is a naturally occurring silicous rock. Perlite is a great product to mix in with soil as it improves aeration (which can result in faster growth), prevents nutrient build-up and it modifies the soil substrate by keeping it loose and well drained. It is a great addition to potting mix for succulents. You can add up to 10-50% of perlite to the total volume of your potting mix. Perlite is an ideal growing media for hydroponic systems.

Perlite is not suitable for ponds or aquaponics as it will float and can be harmful to fish if swallowed!
