Basalt Rock Dust Soil Amendment Reviews

The 44 lb bag will last a long time. I like using it to help give grit to the worms in my garden. It does have bigger fragments though, which I don't think is a bad thing. I want different particle sizes.

I have not used this product yet, but I am glad it is standing by for the upcoming season.

Not sure how well it works since I just got it, but it got to me earlier than I expected!!!

Another of many important ingredients to your soil, add volcanic minerals to the soil, think about all the places great weed grew wild, most of them were in volcanic soil. Basalt is from lava, and that's from volcano's. Now you don't have to wait for nature to break it down over several million years and add it to your soil, compost, and any garden you have.

Small pieces and fine powder perfect for my soil.

Put this in my worm bin, and compost piles and tumblers

Tgis is one of my favorite amendments. Helps to balance soil ph is a major plus

Looks like gravel. Does great in flower based compost teas and top dressing during the flowering stage. I am getting bigger yields and better tasting flowers.

Hard to get alot of these materials on the east coast.

Absolutely the best deal for minerals around! Super stoked to build some soil, especially knowing the quality inputs.

Great soil amendment to add to your regimen! Plants love it and it helps increase your Cation Exchange Capacity in your soil as well! A must have!!

Plan on reusing my soil so I figured this would help

I mix this into all my beds and pots and always makes the plants happier, really seems like you can use it anywhere.

Good high quality basalt rock dust! Working great!

I don't see anything, but I guess it does wat it needs to do for the soil right 🤷‍♂️

I mix with Montana grow in soil I make and test. Currently have 1 compound genetics Apples & bananas in 15 gallon sub irrigated wick pot that's week 4 and fills up my 3x5x7 gorilla grow tent. I'm weekly feeding organics alive bloom adding YAWAY @ 60 ml per gallon. Weekly feeding of growing organics beet & carrot or sprouted quinoa ferments. Just chopped a permanent marker and a bubba whip. Now same soil 2nd run growing healthy giants. I'm going to top dress build a flower and Narley barley tomorrow for that top flight shelf insurance.

Bag was fresh, the product was nice consistency and moisture level. I have no idea if it’s doing anything right now I did top dress it about three weeks ago. My plants are looking beautiful, but I know it takes long tme to break down.

Always quality material from build a soil.

Heart lots of good stuff. Haven't got to use it yet, but we'll be soon.

I really like the texture but could a little bit of more information on how to apply it in a living situation

Love to use this in my mix and top dressing some house plants form time to time

I think this product is really helpful in improving soil quality.

While all volcanic rock dusts are fine for soil amendments, basalt is my personal favorite. If you get it from BAS, you can assure the quality is top notch.

Fantastic quality basalt rock dust. On par with Gaia Green but for a better price. Ever since i started adding basalt and glacial rock dust to my soils, my plants have been growing bigger, thicker and fuller than they ever have before. Some thanks also goes to Jeremy for helping me figure out what my plants needed through all the educational YouTube videos 🙏👍 SB; I was fighting a mystery deficiency which turned out to be a calcium deficiency. Ever since fixing that with some rock dust and gypsum, things have been smooth like butter.

Seems like my plants are loving the product

Good quality but had some chunks I discarded. I will be purchasing the" flour-grade " next time.

Hope it works, I’ve read a lot about it. Super fast delivery! Awesome!

Great way to build your own soil.

Excellent product game changer for my soil

Great all around amendment. Gives the soil a good texture as well

You can just tell it’s a quality product fresh out the bag. Awesome stuff

Using the correct inputs when making soil is imperative. Knowing that I am getting a quality product is key to making great soil.

I trying to use natural fertilizer.

THE cleanest rock dust I've ever seen on soil tests! All forms of plants,veggies,and flowers seem to really love this basalt. An absolute for any and all succulents,as most delicate plants prefer micro over macro nutrients,plus basalt is similar to the local soil types succulents and cacti are grown in,compared to the peat and coco based medias,that are the furthest thing from a volcano as you can get. Absolutely love B.a.s. basalt,when combined with Montana grow silica,it's a grand slam for houseplants and starts to any garden

Perfect for remineralizing my container garden

I've been reamending my vegetable garden they sure have been awesome in the greenhouse and tent

I needed to mix a fresh batch of soil for my veggie garden. Absolutely wanted basalt as my rock dust input. Shipping was so fast. I ordered on the day before Easter. It arrived the next Friday. BAS team is awesome!

Waiting for plants to start growing. Don’t see anything happening .

Great company, great products and great customer serfvice

One of the fundamental components of my grow's

I love all your products! They all have a place. As for basalt, I really like the texture it gives the soil not to mention it’s a great source of minerals. Thanks for all you do we love it here @ adirondack_grower

I appreciate the varied size from sandy through pebbles. It had a couple small rocks too. Perfect to keep supply of basalt in the garden soil.

REALLY GOOD. i love that it varies from small pieces to dust. great for lophophora as well ;)

Tons of minerals and weight added to the soil has all the micro nutrients and some of the metals that you actually need and are missing from most soils. Perfect balance to be able to light put in your soil slowly Leach the nutrients and stay in your soil for a long long time!

I Like it because it is like sand, not powder.

Are you growing in soil or soilless medium? Well, as Jeremy once said in the 10x10 series, it's the addition of copious amounts of rock dust that makes our soil as close as we can get to replicating the natural soil environment. I have azomite but I worry about the heavy metals. So I bought the basalt to use off and on from azomite to help limit the heavy metals. That said it's a bag of crushed rocks, so there's not much to say about it's appearance. However, it has a nice dark rock hue, unlike the azomite I have that is more tan in color.

Coot is proud of the super villain esc efficacy, this basalt crust dust is stupendous, tastes about how you'd expect, plants love it!

Great remineralizer for your soil food web!!

I grow in 6 gallon fabric pots but I reuse my soil. I store used soil in 30 gallon tubs and re-amend it with various additives including basalt. I then let it cook for a couple of months before reusing. I have some soil than been through this cycle multiple times and this is where the basalt really shines. Once added it's persistent and doesn't need to be used again.

As with all the BuildASoil products I've purchased it came properly packaged for transport and for storage of extra product. The semi-moist crushed Basalt was seemingly clean and void of non-Basalt media also.
