Improve Your Compost & Grow More

Perlite volcanic rock granules are added to seed and potting compost to improve aeration, moisture retention and drainage. Perlite stimulates healthy root growth, helps increase nutrient absorbtion and water retention. Perlite is especially useful for outdoor potting mixes as prolonged wet weather can result in a soaked airless compost where plants struggle to survive.

Plants grown in containers tend to be over rather than under watered so creating an open, aerated potting mix is essential. Adding perlite and aerating your compost promotes good root growth and reduces the risk of root disease.

We recommend watering the perlite granules before use to reduce the amount of dust when mixing with your compost. For mixing with potting compost use approx 25% perlite by volume.

Available in 10, 20, and 100 litre bags. Just hit the Bag Size tab to choose the size

The most difficult thing about propagating seedlings is ensuring that the plant grows to have a healthy root structure during its infancy. When I first started planting I found that I really overwatered my seedlings which led to a lot of leggy and useless crops but I discovered this stuff here. Its a great product and really gives the plants a boost to the root structure which means they will do exceptionally well when planted out. I usually use just a pinch and it works really well. A great product.
