Perlite
Being an inert material, recycling perlite poses no environmental problems. Re-using perlite without processing to grow successive crops is potentially risky because of media compaction, salt build-up, and pest contamination (Hanna and Smith, 2002). Replacing used perlite with new media to raise successive crops is costly, and recovering the ...
