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.

It’s half the size of the last one that I purchased. It’s hard to tell from the pictures sometimes.
Should always check the dimensions of items because the pictures can mislead you sometimes The bonus is a great product. It lasts a long time and it doesn’t break. I give this product five stars excellent but the size I purchased is for a smaller dog. Best Bone is what Wakanda growled. Thanks everybody 🚀🇺🇸

The only chew toy that has actualy held up...for well over 2 years!
Size: Medium, Style: 4 Pack, Size: Medium, Style: 4 Pack
These things are amazing! They last forever even with dogs that can destroy nearly everything else in mins! I ordered these as a doggie Xmas gift over TWO YEARS AGO, and they are still pretty much fully intact! They chew on them all the time, too!(see pics; that's over two years of steady use!) I only got the one 4 pack, and have 4 dogs, too! Since making them so well does kind of reduce my ability to buy many more from them, I feel I should at least let people know they really are crazy durable and dogs love them! I will prob buy another 4 pack soon, just so they are easier to find(end up under couches,etc). Def a good buy!!!!

Built for heavy chewers and actually holds up
Size: Medium, Style: Fishbone/Wishbone
This chew toy is a total win for heavy chewers and has held up really well compared to so many others we’ve tried. It keeps dogs busy for long stretches and they stay genuinely interested in it instead of destroying it in minutes. The shape makes it easy for them to grip and chew comfortably, which adds to how much they use it. The durability is the real standout here, making it one of those rare toys that actually earns a repurchase. The material feels sturdy, it’s easy to clean, and there’s no noticeable odor, which is always a plus.

Definitely recommend
Size: Large, Style: 4 Pack
My dogs absolutely love these! I bought them at a great price! They have lasted my dogs over a year! I have a full pitbull, pit/lab, pit/boxer, and a pit/mastiff. So needless to say they pass the power jaw test. They look just like the pictures and they are pretty light weight!
