Donut ring in substrate cubes

Cubes with water chambers are often used in the production (propagation) of tomato plants. This water chamber a so called ‘donut ring’ will allow a more even distribution of the water throughout the cube. The dripper is positioned inside the donut ring to ensure that the water does not run off the block when it is covered too much with algae or weeds. This means that water is always available to the plant. All the water is available, but without the moisture continuously touching the base of the plant. 

  • The plant-hole is in the middle of the water chamber; the depth of the channel is variable.
  • Applicable for cubes with 1 plant hole.
  • The chamber is 12 mm wide and 10 mm deep.
