Pumice Stone Grow Media - Made in USA - OMRI Listed - Bonsai • Succulents • Cactus • Orchids - Horticultural Soil Amendment Additive Conditioner for Indoor/Outdoor Plants and Organic Gardens.

This pumice is the real deal. It is high quality, uniform in size, generously portioned, and securely packaged. I purchased this particular pumice after sampling a few other brands available on Amazon. The other brands left much to be desired -- they were often dirty, gritty, and inconsistent in size. Although some competitors charge less for a similar quantity of pumice, the difference in price is negligible when it comes down to overall quality. As you can see from my photo, the pot on top (terracotta) is filled with pumice from a similar listing by a different brand. The pieces are larger, rougher, and vary in size. The pot towards the bottom (plastic) is filled with Cz Garden pumice. The pumice by Cz Garden is smoother, cleaner, brighter, and consistently sized. There is simply no comparison. This pumice comes packaged neatly in a sturdy and resealable plastic bag with lots of printed information regarding the product. While others have complained about the Bible quote on the bag, I am not bothered in the slightest. On the contrary, the controversy surrounding the quotation was rather amusing. It was, in fact, one of the deciding factors for my purchase. A quotation from Genesis regarding the creation of plant life is hardly an attempt to proselytize; rather, it is a celebration of the mystery and wonder of our created universe. Some interesting food for thought: a "new age" or "secular" quotation would have either gone unnoticed or celebrated. Go figure. Thank you to Cz Garden for creating a superior product, for honoring the mystery of creation, and for celebrating our imitation of God's love for this world through the simple act of gardening. You have earned yourself a loyal customer.

I use this pumice as part of my pon mix for my semi-hydro houseplants, and it’s honestly one of the better medias I’ve tried. The pieces are a nice, consistent size—nothing too dusty or too chunky—and it gives my roots the airflow they need. My plants respond really well to it, especially my Alocasia and Philodendrons. It mixes easily with LECA or larger rocks and doesn’t break down quickly. Definitely a five-star product for anyone doing semi-hydro or wanting a lighter, airy mix.

I used this to grow cuttings in, and top off potted soil based plants to keep fungus knats from breeding (they don’t like this, and it is a deterrent to them breeding on the top soil layer- and it did work for me! ). And the potted plants look good with this as a mulch also! Is expensive for larger scale use, so check out what you’re getting. This bag seemed to be about1/2 gallon , for reference. You still need to rinse it before using, and a finer mesh strainer will do fine.

Worked well for my succulent and cactus mix that I put together myself.

I use a Litter Robot 4 and was looking for something that was less tracking that Arm&Hammer Slide. This worked well in the LR4, but my Pearl is just a pro at mudpies and kicking rocks.

consistent small size stones, low dust. good for custom soil mixes

I bought this specifically for a lithops setup. It was recommended to me by a member of a Facebook group about succulents. It was just enough after I blended it with about 10% organic material. I'm going to buy a couple of more bags to mix with my succulent soil from now on! Perlite is cheaper, but it will float to the top of you top water and it gets everywhere. But like perlite, you don't wanna hale this dry. So the quality is amazing! The color is neat and blends well with the soil. It's easy to use. Just dampen it, dump, and mix. It's small but that's perfect for what I use it for, especially the lithops. The functionality is great! It doesn't float away or blow around. I'm absolutely buying this again!

I love this stuff! I find that plants with smaller roots like substrates with smaller particles. I mix it with perlite and aquarium substrate for a perfect “transition mix” to move plants from soil to semi hydroponics. (The trick is to use a wick setup, not a self watering setup where the substrate is submerged).
