A natural, coarse-grade pumice that supports healthy root systems in larger pots and more mature plants. This pumice size is ideal for growers who require increased drainage and airflow while still maintaining nutrient-holding capability.

With pores that naturally absorb and slowly release water and nutrients, it helps create optimal growing conditions in bonsai, succulents, and cactus gardens.

Features

  • Coarse particle size: 4–20mm

  • Excellent for drainage and aeration

  • Retains water and nutrients in micro-pores

  • Fully washed and screened – no dust or fines

  • Sustainably sourced from a land-based site near Lake Taupo, NZ

  • Naturally sterile, pH-neutral, and chemically inert

  • Suitable for hydroponics, raised beds, pots, and dry-loving plants

Why You Should Buy

This coarser grade of pumice is especially well-suited to larger plants, including older bonsai and large succulents, which benefit from increased airflow around roots. Unlike soil additives that compact over time, this pumice maintains its structure long-term. Its superior drainage minimizes the risk of overwatering, while the porous surface helps hold just enough moisture and nutrients for gradual release, supporting stronger, more resilient plants.

Common Applications

  • Bonsai cultivation with a need for heavier drainage

  • Cactus and succulent soil mixes

  • Soil amendment for large pots or garden beds

  • Hydroponic growing as part of an inert medium

  • Soil conditioning in no-till gardening

FAQs

What’s the difference between this and the 1–7mm grade?
The 4–20mm grade has larger particles, offering even greater drainage and airflow, making it ideal for larger root systems or plants in bigger containers.

Is it pre-washed?
Yes, it's washed and screened to remove dust and fines, ensuring it won’t compact or “concrete” in your soil mix.

Can I mix this with organic potting soil?
Absolutely. It can be mixed directly with soil to improve structure and oxygenation.

Will this break down over time?
No, pumice is a long-lasting mineral aggregate that keeps its shape and function.

Can it be used in hydroponic systems?
Yes, it’s inert and pH neutral, making it perfect for hydroponic applications or as a base media layer.

Tough ball. Perfect for large chewing breeds.
Color: 3 Colors
My German Shepherd Dog is a year and half old, and she loves these. They truly are pretty indestructible. It took her a little bit to figure out how to squeak it bc they are tough, but now it’s easy for her. They bounce well too. They are larger than a normal tennis ball but a good size for a large dog. Luna is 85 lbs. I would purchase they again, but I probably won’t need to for awhile.

Enjoyable For Our Dogs
Color: 3 Colors
Very durable material. They have a little squish too them for easy pick up for our 50 pound dogs. Our dogs love all balls. They have a little weight to them, but not excessive for a medium to large size dog. We have an English Springer Spaniel and a Goldendoodle. Fun for playtime, but you probably won’t want to throw them around the house.

A little too hard for our dog.
Color: 4 Colors
These are definitely durable balls. They are a harder than our dog prefers. He does play with them a little and enjoys squeaking them, but he doesn't like to play fetch with them and that is primarily the only thing he really enjoys doing with balls.
