Pumice makes an excellent soil amendment providing structure, aeration and moisture regulation. Its porous surface absorbs excess moisture, releasing it steadily back into the substrate as required by roots. Pumice contains very few trace minerals but can be ‘activated’ by soaking it in a nutrient solution for 24 hours before use. Alternatively, you can combine it with Worm Castings for a natural, gentle nutrient source.

Fine Grade is measured at 1-3mm

Please note: Pumice is a natural product and its appearance may vary slightly from the image.


  • 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.

Customers praised this fine grade pumice for excellent quality and fair pricing. "Just right for succulents and cactus growing," with pieces around 2-4mm that are gritty but not powdery. Shoppers appreciated the resealable packaging and fast delivery. One suggestion was to offer larger 5L bags instead of multiple 2.5L bags.

  • Excellent quality and reasonable price. Just right for succulents and cactus growing.
  • Really great quality, regular sized, even shaped pumice. Lovely to work with.

I ordered Pumice fine grade and medium grade, orchid bark, clear pots, worm castings, LECA to create houseplant potting mix.
*it would be nice if all of them come in one 5 litres bag instead of 2 bags of 2.5 litres. Otherwise everything is great*

They’re all good quality, good price, I really love their packaging.

they replied really fast when I was asking them some questions.

I received all of them with next day delivery.

I would be ordering from this shop again in the future.

Excellent quality and a reasonable price. Fine grade is just right for succulents and cactus growing. Gritty enough to be useful, not at all powdery, but not big pieces. Around 2-4mm. Perfect. Supplied in a resealable pouch for convenience and secure storage. I would recommend this one.
