Small Black Lava Rock Reviews

Unlike the pumice the black lava has a lot of dust in it. Be nice if it was screened. Trying to get all the ingredients to make a good bonsai mix. Glad you have the pumice and lava. Still looking for a good substitute for akadama. Any ideas?

Its part of a recipe, I got what I paid for.

I’d recommend just buying the full cubic foot. You don’t save much by ordering less. Was kinda disappointed with the amount in the bag compared to the full cubic foot size

I like to use this lava rock to add more texture to my soil. Great aeration component!

Overall this is a great product, with all the benefits described, although I take issue with the idea of using this as one's only aeration amendment. The particle size was quite a bit smaller than I expected, which is perhaps just a mistake on my part, and I should've bought the larger size. This product is only slightly larger in size than the biochar, and seems to disappear when mixed into the soil. I added A LOT of rice hulls to my mix to get it to the right consistency. I probably will not buy this again, unless perhaps to use as a top layer of "mulch" on smaller containers to prevent fungus gnats and uneven drying.

It’s impossible to pull out a handful that looks like any of those pictures. I filtered a half cubic foot of it through an ⅛” screen and got 2 gallons of fines. I might top dress a couple of tablespoons of that every now and then.
