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

  • We always aim to make sure our customers love our products, but if you do need to return an order within 14 days of purchase (not including plants*), or any items are damaged, we’re happy to help. Just email us directly at hello@growtropicals.com, and we’ll take you through the process. 

    Please note: we cannot be held liable for any packaging costs should the original packaging be discarded.

    *Unfortunately we cannot accept returns of undamaged plants as these are perishable items and are not saleable upon return. If a plant is damaged, we will compensate for this as per our live arrival guarantee.

  • When placing your order, you can choose from three dispatch speeds to suit your needs: Economy (prepared and shipped within 4-5 days), Standard (3-5 days), or Express (dispatched the very next day). Please keep in mind that "dispatch" refers to the time it takes our team to prepare and pack your items before handing them over to the courier, not the total delivery time.

    Shipping costs are based on your total order value and will be calculated at checkout, with free shipping automatically applied to all orders over £60. For a full breakdown of shipping prices please see our help center here.

    Additionally, to protect the health and quality of our live plants, orders containing plants are exclusively shipped Monday through Thursday. This careful scheduling prevents your plants from being stuck in a dark shipping depot over the weekend, ensuring they arrive at your door vibrant and healthy.

Fine-grade horticultural charcoal praised for excellent quality and value. Customers said it's "uniform in size" and "not at all messy." Widely used in soil mixes, terrariums, and houseplants. One customer preferred coarser grade. Praised for minimal dust, great packaging, and competitive pricing. Ideal soil amendment component.

  • Quality and price is excellent, no dust just good size charcoal.
  • Uniform in size/shape and not at all messy considering what it is.

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.
