Pontastic is an alternative to soil or potting mix for your plants. It is a hand mixed, high quality, pure mineral substrate for plants.

What is Pontastic?

Pontastic is a specially balanced mixture of minerals that can be used to pot your plants into instead of soil. Pontastic is suitable for all plants. It acts as a semi-hydroponic mineral substrate medium to support your plants effective growth. Pontastic also contains a small dose of slow-release fertiliser to keep your plants fed for up to 6 months of growing.

Pontastic can be used as an alternative to LECA or LECHUZA-PON.


Why should I use it?

Some of the many benefits to using Pontastic for your plants:

  • Easier cleanup, no dirt or soil.
  • Suitable for all plants.
  • Does not allow Fungus Gnats to nest and blocks them from spreading in your home.
  • Extremely well-draining and will not saturate your plant and roots, reducing the possibility of overwatering and rot.
  • Ample air flow to the roots of your plant. Supports the right balance of water and air.
  • Works very well in a self-watering pot and effectively transfers moisture up into the roots using capillary action.
  • Does not degrade over time like potting mix or soil. It can be used for as long as you want and doesn't need to be changed.
  • It can be reused over and over.
  • It is pH balanced and stable.
  • It also looks great!

Which plants does it work with?

Pontastic is suitable for all plants, but some plant types especially love it and will thrive in it, such as:

  • Hoya
  • Calathea
  • Ctenanthe
  • Maranta
  • Philodendron
  • Alocasia
  • Ficus
  • Monstera
  • Dieffenbachia
  • Aglaonema

How to use it?

  1. Rinse Pontastic with water before first use to remove any dust that has formed during shipping and transport.
  2. You can "ponvert" your existing plants by carefully removing the soil or other medium from the roots as much as possible and re-planting them into Pontastic.
  3. You can plant your cuttings or propagations straight into Pontastic.

The Pontastic 3 Litre size will pot up to:

  • 27x 50mm Pots
  • 6x 100mm Pots
  • 2x 140mm Pots

Great product. Be better in 10kg packaging.


I wish I could show a photo of my newly potted indoor plants in the Pontastic pebbles. My Calatheas survived the shock and now they’re really happy in their new home ☺️
