The quality is top-tier, the benefits are undeniable, and the versatility makes it a staple in my home. I highly recommend it—this is one of those products you don’t realize you need until you try it!💡 Pro Tip: Rinse before use to remove excess dust, and mix it with potting soil for optimal results.

Exactly as described, well packaged, arrived on time, works well for my purpose

Great texture and lots of surface area for little microbes to make a home, hold extra nutrients, and to fluff up soil structure. Remember that the first year you add biochar, it actually *takes away* nutrients, as it gets "loaded up" in all of the tiny pores. That's okay; the payoff comes in the following seasons to come. Great product; will buy again.

I used this for my all my Vivarium and Bioactive reptile enclosures. This is by far the best I could find anywhere for Horticultural grade charcoal. Bought multiple times and will again.

It arrived promptly. I’m repoting a couple of tropical plants and horticultural charcoal was recommended to prevent mold and other nasties, fungi etc. I decided to try Amazon when the hardware store didn’t have this item. Amazon did not let me down and I was happy to have it delivered promptly. I appreciated the written warning that the product is a source of arsenic and urged me to take precautions such as wearing a mask and gloves while working with the production hadn’t expected that.

I bought this because I saw the word Horticultural and figured this would be a great addition to my potting mix.It's odorless and absolutely no dust that I could see. I was hoping it would be a bit chunkier but I'm still completely happy and so are my plants!I'm attaching a photo so you can see the size of the pieces in the package. I may just stick with this size after all.

This charcoal gives the best results and the plants show a hartiness that gets comploments.

Product arrived on time, now waiting to see how the plants do after using this.
