Key benefits

  • A staple in aroid, terrarium and vivarium substrate mixes
  • Light drainage material, half the weight of calcined clay
  • Supports springtail cultures inside a vivarium
  • Fine grade, 2-5mm

Amazonian peoples use charcoal as a key ingredient of their terra preta soils, and today it is a staple component in nearly every substate mix used in the aroid, terrarium and vivarium hobbies.

In addition to its use as a substrate, it is also an excellent material for culturing live foods inside the vivarium, particularly springtails (Collembola) – filling the trough with charcoal supports an ongoing food source for freshly morphed froglets. Because it weighs half as much as calcined clay, it also makes an excellent drainage material that will help reduce the overall weight of your vivarium display.

When storing charcoal, allow it to dry out completely before placing into an airtight container.

Fine Grade is measured at: 2-5mm

How to use
  1. Mix it into your substrate, or use it as a drainage layer
  2. Fill a vivarium trough with charcoal to culture springtails
  3. Let it dry out completely before storing it in an airtight container

Perfect quality and price

I use horticultural charcoal in all my house plants and wouldn't buy it anywhere else. The quality and price is excellent, no dust just good size charcoal. Grow Tropicals are the best, not only for plants, but soil and soil components. I wouldn't shop anywhere else.

Experiment with moss poles

I'd seen some videos online of people including charcoal in their aroid mixes and noticed it being sold here when looking for other aroid mix components. It's my first time trying it but so far a good experience. It is all uniform in size/shape and not at all messy considering what it is.
