Persist Horticultural Charcoal 1.5 cuft, Biochar Soil Amendment for Plants, Improves Soil Quality, 100% Natural Active Carbon and Fertilizer Enhancer for Gardens.

I use this in the terrariums I build and sell as well as in all my potted plants in my home.Great value and the quality is exceptional!

We bought a large bag to see if Biochar would help abate jumping worms in our gardens. It did help but the expense of this solution led us to other options.

This 30-lb biochar was not dusty and the granules were easy to mix with ingredients to charge it. Per another reviewer, it is much easier to use than crushing natural charcoal briquettes or creating biochar from scratch. Many online sources and YouTube videos explain how to innoculate raw biochar like this. I used a large galvanized tub and mixed the entire bag with humic acid, Azomite, kelp, a 25-quart bag of worm castings, flour, molasses and filtered water. Some people use compost, liquid fertilizers, fish emulsion, etc. Anyway, the slurry sat for two weeks to charge up.

Excellent consistency, fair priced. There’s a noticeable difference in overall plant development when not using this product. Combined with humic acid and other nutrients and microorganisms to charge it will nearly double your yield.

For me it’s excellent I recommend it very highly

This would be great as biochar for a nutrient- and microbe-holding soil additive. The particles look perfectly uniformly sifted to about 1mm. Would have honestly liked some variety of irregular sizes for more soil structure. I liked Harris brand better in that regard. Made in California.

I love using activated charcoal in all my plants and terrariums. This was the perfect consistency and a huge bag for a decent price. I would definitely recommend and will be buying again in the future.

Nice and fine easy to mix with your potting soil , I've bought 4 bags
