Perlite is a naturally occurring volcanic mineral, small black crystal like when mined. It is heated to 1100°C, then explodes like popcorn to form white granules similar to rice bubbles in look. Very light, sterile and pH neutral. Best for recycling and non-recycling hydroponic systems.

Use perlite/vermiculite 2:1 for its high water holding capacity in warmer months (late spring, summer, early autumn). Excellent for use with sandy soils and adds aeration to clay soils.

Vermiculite is a flaky material, when heated exfoliates, splitting the layers apart and giving light, spongy golden granules. It can hold 67% by volume of water. Very light, sterile and pH neutral.
For extra aeration use perlite/vermiculite 2:1 with a good quality potting mix for seed raising and cuttings. In general use with potting mixes to prevent soil compaction and assist drainage.

Use with Ag-Grow Grow or Ag-Grow Bloom nutrient for superior results.
