Zeolite - 1/2"

Zeolite Soil Aggregate (3/8" - 1/2")

Our largest grade of Zeolite, screened to 3/8" - 1/2" for drainage layers, top dressing, and large containers. Chunky enough to keep water moving through the bottom of a deep pot while still doing the nutrient-holding work that makes zeolite worth using in the first place.

Why growers love Zeolite:

• 🪨 Maximum Drainage & Aeration – The largest particle size we offer, for pots that need water to move fast.
• 💧 Excellent Water Regulation – Holds moisture within its porous structure while allowing excess water to drain away from the root ball.
• 🌱 Naturally Holds Nutrients – High cation exchange capacity (CEC) captures fertilizer and releases it to roots over time.
• 🌿 Cleaner Than Gravel – Unlike inert rock, zeolite is working for your plant even at the bottom of the pot.
• ♻️ Long-Lasting & Stable – Does not break down or decompose. Rinse and reuse.

Perfect for:

• Drainage layers in semi-hydroponic and self-watering containers
• Top dressing that will not blow away or wash out
• Large specimen trees and oversized containers
• Aquarium and pond filtration media
• Orchid and epiphyte mixes needing maximum air space

Our horticultural zeolite is chemical-free, contains no added fertilizers or pesticides, and is ideal as a standalone amendment or as part of a custom soil mix.
