Review: Very fine! - Mixes easily into my potting soil.
Review: Exactly what I wanted :) - Works great and super fine grain to mix! I mad e a new mix and use orchid bark, charcoal, and fox farm soil for my plants. My plants are *thriving*. It’s probably a combination of all 3 and I was holding my breath that I’d kill them but they’re rocking it. This charcoal is the perfect additive.

## Features

- IMPROVES SOIL - Persist Biochar soil amendment active charcoal improves nutrient availability in potting soil for indoor plants and terrarium soil by holding onto nutrients due to its high surface area and porosity, preventing nutrient loss and making them available to plants for longer.
- MOISTURE ABSORBER - The porous structure of activated charcoal for plants allows water to be retained in the small spaces within the material, which helps to reduce water loss. High surface area of biochar allows it to hold onto water molecules to keep potting soil for indoor plants hydrated longer.
- INCREASED PLANT GROWTH - Persist Biochar prevents leaching of valuable water and nutrients from the soil, improving the effectiveness of house plant food and accelerating plant growth for all types of soils including orchid soil, succulent soil and bonsai soil for indoor plants and terrarium soil.
- TERRARIUM SUPPLIES - Moisture eliminator activated charcoal for terrariums is an essential part of any terrarium that enhances soil drainage in terrariums or potting soil. Persist Horticultural Charcoal improves soil structure resulting in increased oxygen in the soil, making it naturally fertile.
- THE CORAL REEF OF THE SOIL - Just as a coral reef's crevices provide a habitat for diverse marine life, biochar's microscopic pores act as a home for microorganisms crucial for sustained soil and plant health. Persist Biochar enhances both the variety and number of beneficial microorganisms in soil.

## Questions & Answers

**Q: What country does it come from??**
A: Persist Biochar is made 100% from California pistachio shells here in the United States. The manufacturing company is VGRID Energy Systems which uses their bioserver technology to convert AG waste pistachio shells into clean energy and they extract Persist Biochar from the process. The bioserver uses a high Temp/low gasification process to ensure the biochar is pure and has a very high porosity value for maximum adsorption capacity.

**Q: How many quarts is this (1.5 cu. ft) equivalent to?**
A: The formula for finding out how many quarts is in 1.5 cuft is: to multiply the volume value by 29.922078. So the answer to your question would be 44.8831169 quarts

**Q: Is this good for clay soil?**
A: Horticultural charcoal is good for just about any soil and clay is no different.  This will be a great additive for clay soil.  I live in a clay-heavy area of New England and this has worked great in my garden and overall yard plantings (not to mention potted plant soil). On this issue though, I will say if you do have a substantial majority of clay soil and the amount of topsoil that would be needed to noticably/fully improve it would be unrealistically cost prohibitive, a spring and summer of garden gypsum is absolutely critical to aid in creating a suitably draining soil.  Mix that with the charcoal and you'll see a marked improvement.  Good luck!

**Q: horti charcoal for plants & active carbon bricks purify horse's water troughs—similar benefits but active carbon is better; does this work the same?**
A: Charcoal/carbon is classified on a range or spectrum. From the charcoal you get from a campfire to pharmaceutical active carbon. The latter is used to filter water and air for purification purposes, though many DYIs survivalists and such show how you can use the low-grade charcoal when additional precautions are made. Persist Biochar is made using a low oxygen high-temperature process which creates a very high surface area and would be considered a low-grade active carbon. In saying that, Persist Biochar is not approved or tested to purify drinking water for animals or people.
