J. Arthur Bower's Hydroleca

J. Arthur Bower's Hydroleca
  • A lightweight ceramic pebble with a honeycomb centre
  • Protects from overwatering and creates a beneficial micro-climate
  • Decorative pot topping
  • Size 20 Litres

J. Arthur Bower’s Hydroleca is formed from ceramic clay ‘pebbles’ with a smooth, dense outer skin and a honeycomb interior. They are ideal for use as a decorative pot topping, crocking and benching. The pebbles absorb water and release it slowly. They also have good insulating properties due to their cellular nature. Hydroleca does not compact and is unaffected by frost which allows it to be used outdoors as well as indoors where the pebbles’ light weight is of immense benefit in roof garden plantings.

Decorative topping

Sprinkle a layer on the compost surface of pots, containers, window boxes and tubs. It can be used both in and outdoors.

Houseplant care

Place the plant pot on a layer of Hydroleca which will absorb water and release it slowly to prevent root damage caused by the pot standing in water. The humid microclimate created around the plant is especially beneficial in centrally heated homes.


Put a handful of Hydroleca in the bottom of pots and containers as crocks before filling with compost for improved water retention and better aeration to improve plant root growth and plant health.


Fill a tray with a 2cm layer of Hydroleca and place plant pots on top. Keep the Hydroleca moist so that it gradually releases moisture to the plants placed on its surface and improves greenhouse humidity.

Balconies and roof gardens

Add Hydroleca to potting compost in a ratio of one part Hydroleca to three parts compost for lighter weight containers to grow a wide range of plants, including small trees and shrubs. Hydroleca can also be used as the drainage layer in a green roof planting of drought-tolerant plants such as sedums.
