Perlite Super Coarse by Exfoliators

Our largest grade Perlite. Ideal for Orchid growers and users who want added structure to their potting mixes, especially for large volume pots growing advanced plants. Also used extensively in waste water treatment as a filter media. Other applications include home hydroponic systems and Aquaponics. Super coarse Perlite is inert and non toxic, it has a very low Cation exchange capacity allowing for excess salts to be easily leached.
