Description

Key benefits

  • Adds structure, aeration and moisture regulation to soil
  • Absorbs excess moisture and releases it steadily to roots
  • Can be activated by soaking in nutrient solution for 24 hours
  • Fine grade, 1-3mm
  • A natural product, so it may look slightly different

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.


How to use
  1. Mix the pumice into your substrate as an amendment
  2. To add nutrients, soak it in a nutrient solution for 24 hours first
  3. Or combine it with worm castings for a gentle nutrient source

Verified reviews

Rated by real customers

Fine grade pumice highly praised by customers for excellent quality and reasonable pricing. Ideal for succulents, cactus, and houseplant potting mixes with consistent 2-4mm particle size. Customers noted "gritty enough to be useful, not at all powdery." Comes in convenient resealable pouches. Minor feedback on packaging size options and occasional courier delays.

  • Excellent quality and reasonable price. Fine grade just right for succulents and cactus growing.

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.
