Buying Guide

Match media to plant needs

Choose inert media like LECA or hydroton for general hydroponics and clay-pebbles for strong drainage; bark performs better for orchids and epiphytes that need more air

Consider particle size

Smaller pebbles (4–16 mm) pack more densely and retain more moisture, while larger pebbles improve aeration and drainage for faster-growing roots

Check weight and volume for system size

Compare bag weights (e.g., 16–19 lb options) or cubic feet to estimate how much media you need for your net pots or grow beds

Look for compatibility with cloning or net-pot accessories

If you clone plants, consider foam inserts or collar packs designed for net pots to secure cuttings during rooting

Prioritize cleanliness and reusability

Select media that can be cleaned and sterilized between crops—expanded clay and hydroton are easy to rinse and reuse compared with organic bark
