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

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).

Good for potted plants to increase oxygen at the roots. Will not break down over time like perlitez. The small particle size is perfect for toplayering on potted plants to make them less attractive to fungus gnats.

Great product! Small grains, exactly what I need for my cacti seedlings. And it is practically dust free, ready to use straight from the bag.

Just what I needed to make more soil for my succulents!

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.

Good but pricey

Excellent pumice product!!! Perfect for succulents or diy pin!!

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.
