Horticultural Grade Perlite - Five 8 Quart Bag ~2 Lbs Each - Grade 1, Fine Coarseness (~1/8 Inch Particles) - Soil Amendment Additive - For Growth, Aeration & Drainage for Potting Mix

Pure horticultural grade perlite. Grade 1, Fine Coarseness (granule size about one eighth of an inch.) Perlite is made from all natural volcanic rock that is heated under pressure until it explodes like popcorn, leaving a white puff that is so light that it will actually float. Perlite is added to soil and soil-less potting mixes (like coconut coir) to provide additional aeration, drainage, and insulation for roots against extreme cold. Perlite helps keep soil from compacting. Unlike vermiculite, perlite doesn't hold much water or nutrients, so is ideal for plants that need good drainage or that like soil to dry completely between waterings (succlents, cacti, and a small number of vegetables, flowers and house plants). Perlite has no microbial or nutritional value. Perlite can have pH of netural (7) to slightly alkaline (7.5). Compare to Vermiculite which typically has a neutral pH of 7. You can start seeds in straight perlite, but most potting mixes contain between 10% to 20% perlite.
