Description
Medium Biochar (Grain of Rice size) is a high-performance, micro-porous carbon material made from kiln-processed, 100% renewable natural wood biomass using a controlled, low-oxygen pyrolysis process. Each particle delivers an ideal surface area and structure for enhanced soil porosity, aeration, nutrient exchange, moisture retention, microbial & fungal activity, and contaminant adsorption.
This grade is optimized for users who need a medium granular biochar that works fast in soil, mixes evenly in substrates, and performs reliably in water and storm filtration systems—without the slow integration of large chunks.

Why This Grade Stands Out
Customers choose this grade because it offers:
-
Balanced particle size for both soil and filtration usability
-
Faster activation than large biochar, but more stable than powder
-
Even mixing in substrates with minimal clumping
-
Higher microbial surface support
-
Reliable performance across gardens, farms, greenhouse projects, and environmental filtration
Frequently Asked Questions
1. What is Medium Biochar used for?
It is used for soil conditioning, compost & potting mix improvement, odor control, and water/storm filtration. The “grain of rice” size makes it perfect for balanced aeration and fast activation in growing media.
2. How does it help my plants grow better?
It improves plant health by:
-
Increasing airflow in soil
-
Holding water and nutrients longer
-
Supporting stronger roots
-
Boosting good bacteria and fungi
3. Is this biochar better than powder or large chunks?
Yes. This grade is a middle-ground solution:
-
Activates faster than large biochar
-
Mixes more evenly than big granules
-
More stable and less messy than powder
4. Can it be mixed into compost and potting soil?
Yes. It blends easily into:
-
Compost piles
-
Seed-starting mixes
-
Potted plant soil
-
Greenhouse substrates
5. Does it remove toxins and bad smells?
Yes. It can adsorb ammonia, pollutants, toxins, heavy metals, and odors, making it useful in compost tanks and livestock bedding.
6. Is it organic and safe?
Yes. It is:
-
Chemical-free
-
Sustainably produced
-
100% renewable (wood biomass)
-
Made in the USA
-
Carbon-negative for the environment
7. Will it clog irrigation or filters?
No, not if used properly. Since it is fine granular, it should be:
-
Mixed well into substrates
-
Suspended fully if used in liquids
-
Avoided in ultra-narrow unfiltered drip lines
