Works very well as part of my potted cactus substrate and looks great as a topper.

We ship with FedEx, UPS, and USPS. Carrier preference is not guaranteed unless explicitly communicated to us.
Orders shipped to PO Boxes often require additional costs and are not eligible for free shipping. Use a physical address to avoid delays and fees.
We ship to Alaska, Hawaii, Puerto Rico, Guam, Northern Mariana Islands and the U.S. Virgin Islands. Free shipping generally does not apply to large or bulky items shipped to these locations. Hawaii and Alaska do have more flexibility with this due to carrier policies. Quotes will be calculated at checkout or by request.
We do ship to Canada for select items. Canadian customers must choose “UPS Standard® Shipping to Canada with no Surprises!” at checkout to ensure proper customs clearance and avoid unexpected brokerage fees or delays. Orders using other methods may be subject to delays or rejection at customs.
Some products are fulfilled by vendor partners and display estimated ship dates on their product pages. Questions about these items should be sent to support@buildasoil.com.
Freight deliveries involve pallets via box trucks or semis. Liftgate service is assumed unless specified otherwise.
Important: Inspect all freight shipments before signing. Count and examine all packages. Signing the delivery receipt confirms that the order arrived in full and undamaged.
Orders that qualify for full truckload (FTL) delivery will be custom quoted after checkout. Rates are based on location, order volume, and unloading requirements.
Tracking information is emailed upon shipment. If not received, visit buildasoil.aftership.com and enter your order details. For help, contact support@buildasoil.com.
This low-cost optional add-on at checkout insures your shipment against loss, theft, and damage. Claims are fast-tracked for resolution or replacement.
Even with protection, we encourage submitting photos, videos, and documentation to assist our carrier claims process.
All claims must be submitted via support@buildasoil.com. Phone-based claims are not accepted.
Required Documentation:
Do not discard packaging or damaged items—carriers may require inspection.
Once an order leaves our facility, we are not liable for delays, damage, or misdelivery caused by the carrier. We assist with claims but final decisions rest with the carrier.
We have zero tolerance for mistreatment of delivery drivers. Verified misconduct may result in cancellation and refund of your order minus shipping costs.
Ever noticed how perlite seems to float to the top of your containers, leaving your soil uneven and your plants struggling? It can be frustrating watching your soil shift instead of staying exactly where you want it. 🌱
That's where our Small Black Lava Rock steps in. Screened to 3/8" minus and packed with natural lava rock powder, this mineral-rich alternative stays put, supports soil structure, and even feeds your plants over time. It's everything you wish perlite could be and more.
*Note: Due to our build process and the proximity of our black lava rock and pumice piles, a small amount of white pumice may be present. This does not affect planting use, but for landscaping please be aware it may slightly change the uniform black appearance.
No more floating perlite. This lava rock holds steady, keeping your soil layers consistent from start to finish.
The natural lava rock powder delivers a slow, steady release of minerals that enrich your soil and support thriving plants. 🌋
Unlike perlite that can break down and lose effectiveness, this black lava rock stands the test of time in your containers or raised beds. 💪
Screened to 3/8" minus, these small to medium pieces look similar to perlite but perform even better and the "minus" means that the smaller particles like sand aren't screened out and this makes an excellent rock dust source for living soil and garden beds.
You will want to screen out the perfect size pieces for your use and save the sand particles for your garden or potentially use for bonsai species that require more moisture holding like tropical bonsai.
Nothing added. Just beautiful black lava rock straight from nature to your soil. 🖤
Add 10% to 30% lava rock by volume into your potting mix for best results. Adjust based on your plant’s drainage needs.
Spread a thin layer over the surface of your soil to help with moisture retention and improve the look of your containers.
When replanting, simply rinse and reuse. This lava rock holds up season after season!
