Nice addition to desert tanks!
Adds a nice texture for your desert enclosures. Helps to retain moisture, adds traction in dirt, size is roughly small pebble sized, decent value for money, and these work well for growing plants. They help to root the plant in place and pack it down. The rocks also can provide nutrients for critters seeking minerals from stone/rocks.

Excellent for use with artificial plants.
I ordered multiple artificial succulent plants from Amazon; several pots including a beautiful Mexican Ceramic Pot and the above Lava Rock Pebbles to make several planting. All of them turned out to be very beautiful in my wife’s and my own opinion.Since the plants are artificial & the above Lava Rock Pebbles would have been fairly expensive if I filled all of the pots I had, from top to bottom with them to hold the plants, I did the following to save appreciable costs for stones & pebbles purchases: 1) I got 15-20 lbs of fine beach sand first 2) I filled about 1/2 to 2/3 of the pot with the sand depending on the height of the pot and the length of the individual artificial succulent planting wire at their bottoms 3) then I added to almost the top of the pot the Lava Rock Pebbles that were quite beautiful post preparation 4) Next step was to arrange the plants until my eye and brain were satisfied with the overall look. 5) On one planter pot, the superb looking, $100 Mexican Ceramic 15″ long rectangular one, I also added a centerpiece of artificial orchids surrounded by the lower in height, quite beautiful, variably colored and types of artificial succulents including both upright & hanging types. I also sprinkled a few gorgeous, light gathering, colored, artificial, variably-colored, translucent plastic gemstones, between some of the spaces that I kept between most of the succulents.All of the artificial succulents Orchid , stones and lava rocks and most, but not all, of the pots were Amazon purchases.

Great!
I purchase the 9lb bag. They arrived great. No bag split or damaged. They were very dirty and needed quite a bit of cleaning but once clean up was done they looked amazing! I’m using them as a diy pon substrate for my plants! I can’t wait to see how well the plants turn out! One 9lb bag was enough to fill about 7 5inch self watering planters. So definitely buy more than what you think you’ll need! Will be purchasing again!

Expensive but I love the look on my plants
I wish I could buy this in bulk. Expensive to buy in small quantities. I really like this look to cover the soil on my houseplants and succulents outdoors. I was hopeful it would help with fungus gnats but so far Iâm sticking to a yellow stickies in the plants to get them and Iâm still seeing more being caught. At least it looks pretty and neat on top of the soil if nothing else.

Nice!
These are really pretty once you wash them. I actually mixed some in with my potting mix and then added a layer to the top of the plant pot. Really gives my plants a finished look.

Lava Rock
Perfect for my cactus plant soil.

Great rock, sometimes overpowering fragrance
I’ve ordered this twice. The first time was great, exactly what I expected, just rinsed it and used right away. The second time… wooooah, VERY strong nasty chemical floral-ish scent. I didn’t want to waste the rock if possible, so I rinsed it with water and then let it soak in a diluted alcohol mix *every day* for about a week. Finally the smell dissipated, and it’s usable now. But that is way too much work for what it is :/ Probably won’t order it again, which is a bummer because the first bag was great, and it’s nice looking and great as a semi-hydro plant substrate
