A chunky, soil-free mix for larger semi-hydro setups.

Chunky PON is hand-crafted in small batches from quality mineral ingredients. Its larger pieces allow extra airflow and drainage that roots love, and the mix doesn't compact over time. If your plants have struggled with soggy roots in semi-hydro, the extra airflow in Chunky PON is a good place to start.

Best for

• Larger semi-hydro setups
• Passive hydroponics
• Plants with thick roots, like alocasia, anthurium and philodendron
• Moving tropical houseplants from soil to semi-hydro

Why plant parents love it

• Extra airflow. Large particles keep oxygen flowing around the roots.
• Drains fast. Water moves through quickly instead of pooling around roots.
• Won't compact or break down. All-mineral ingredients hold their shape, so you can rinse and reuse it.
• Zeolite included. A porous mineral that holds onto water and the nutrients you add.
• Fertilizer-free. Nothing added, so you control feeding with your own semi-hydro nutrients.
• Ready to use. No rinsing needed. Open the bag and pot up.

Ingredients

Zeolite, lava rock, chunky pumice, chunky perlite, charcoal chips and maifanitum (maifan stone).

How to use it

1. Rinse all of the old soil off the roots. Leftover soil can rot roots in a semi-hydro setup.
2. Pot into a container with a water reservoir, or a slotted nursery pot sitting in a cachepot.
3. Keep water in the bottom quarter to third of the pot. The PON wicks moisture up to the roots.
4. Add semi-hydro nutrients to your water, and flush the pot with plain water about once a month.

Chunky PON or Classic PON?

• Chunky PON: larger pieces, more airflow, faster drainage. Best for larger semi-hydro setups and plants with thick roots.
• Classic PON: smaller pieces that wick water evenly. Best for self-watering pots and finer roots.

Pair it with our 3-inch self-watering pots, or mix in LECA for extra airflow.
