Small Black Lava Rock

I built a simple.soil recipe using materials from Build-A-Soil with rice hulls, black lava rock and the craft blend along with some compost I had available. My tomato plants are huge. 3 of the 9 are at 6 feet. These three received larger pots and the blend mentioned above while smaller containers received a premade potting mix from a different organization. I also used this blend in several 5 gallon containers and those plants are at a hearty 3.5 feet. All of these plants have tons of flowers all over them!. I am only feeding these with compost tea every three weeks. Thank you Build-A-Soil! Customer for life for sure.

Great product for aeration, I screen out my containers and amend the medium at the end.of the grow. The Lava gets reused.with no issues.

very high quality and clean stuff.

I mixed this up with some pumice and rice hulls and my plants love the texture of the soil and mineral additions it adds. I just took some plain organic soil and threw in some worm casting and lava rock and plants went from yellow green to deep forest green in a week!

Works well. Shipped fast
