Perlite is those little white bits you find in all the best composts. It allows you to achieve those fluffy potting compost mixes, full of air spaces and retained moisture, you've always dreamed of and will give your sowing and growing activities a real leg-up.
Here's the science - perlite is natural volcanic rock which is heated to a high temperature to produce a lightweight micro-porous structure and this material proves ideal for holding air and moisture, reducing compaction. Perlite is a must for any grower. Mix with any potting mix.
Primarily a compost additive, Perlite helps to stimulate root development and growth. Perlite can be used for seed starting, rooted cuttings, potting-on or planting out. If using for seed starting, Perlite’s structure maintains moisture and temperature levels.
