Coarse Perlite | 1/8–3/8 Inch Pre-Sifted Perlite for Potting Soil & Propagation
$13.99 USD
Everyday perlite for lighter, better-draining potting soil.
Coarse Perlite is pre-sifted perlite sized 1/8 to 3/8 inch. It blends evenly into regular potting soil, seed-starting mix and propagation setups, adding air pockets and drainage without making the mix too chunky. It's the easy fix for bagged soil that stays wet too long.
Best for
- Lightening up everyday houseplant potting soil
- Seed starting and rooting cuttings
- Moving cuttings from water to soil
- Cactus and succulent mixes
Why plant parents love it
- Pre-sifted. Dust and tiny fines are screened out.
- Mixes evenly. The medium size blends into peat, coco or compost without separating.
- Better drainage and airflow. Helps keep soil from compacting and staying soggy.
- Inert and pH neutral. Won't change the chemistry of your mix.
- Lightweight. Adds structure without adding weight to your pots.
