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.

Bought this for my son and just ordered me one
Color: Grey, Size: Queen (88" X 88")
My son's college apartment runs warm (that is probably because college students trying to save money) so we decided to order him this cooling comforter. I have been wanting one since entering menopause but never bought one for myself (the things we will do for our kids but not ourselves) so when his came in I told him I was going to use it to see if I liked it and if it helped with the night sweats until we met up to give it to him...those three nights of me using it were enough for me to want one. This is a game changer! It is thin like a blanket so we removed the flat sheet and put this under our regular comforter. My husband needs the thickness of our regular comforter because he says I freeze him out at night. This 'comforter' is so soft, fits the bed great (as a blanket or comforter), and is truly cooling. Now, that's not to say I haven't woken up a little on the warm side but all I need to do is readjust to a cool spot under the blanket and I fall right back to sleep. The grey is very light but it is washable as needed.

Perfffff
Color: White, Size: Oversized King, Color: White, Size: Oversized King
So very comfy! I did not expect to love this as much as I do. I was worried about it being too hot. It’s not. I was used to sleeping with a quilt but this is so comforting, the weight of it is so cozy & perfect. I sized up with oversized king for my king size duvet cover. Its so fluffy and perfect for the aesthetic I wanted

So cozy!
Color: White, Size: King, Color: White, Size: King
I absolutely love this comforter! It's very cozy, soft, and fluffy! I bought it for a duvet that I have and it fits it perfectly. It has loops on all four sides to tie a duvet and comforter together, which is really helpful. This comforter is also breathable so it helps me sleep better at night because I'm not getting overheated. The color and appearance is true to the pictures it displayed. It also seems to be quite durable and good quality. I would definitely recommend for anyone needing a new cozy comforter!

Perfect summer blanket for hot sleepers
Color: Olive Green, Size: Oversized King
Oh my, we love this blanket so much. It's soft it's warm in our 65° bedroom at night I steal sometimes get too hot underneath of it and I have to uncover but it's not as bad as the one I had replaced it with which is going to be our winter blanket this is going to be our summer blanket. Can't say enough about how soft and cozy and comfortable this is it's not a heavy blanket which is not what we wanted anyways and when I make the bed it looks very nice and not puffy.
