User guide

UGro Slab is a peat-free, eco, sustainable coconut substrate with low EC levels and minimum nutrients. It is packed into a large slab in plastic wrapping which is easy to use and easy to reposition. The bag has been treated for excellent UV stability.

  • What you will need: UGro Slab, x4 UGro Cube Rhiza, scissors, clean water, root stimulator and fertiliser.
  • There are four cubes marked for cutting on the top of the Slab and drainage holes underneath the Slab.
  • Few hours prior to planting cut one of the cubes and proceed to hydrate the slab.
  • Saturate the slab with 6.5 litres of clean water through the cut hole. Do not exceed this amount of water as this is can affect root development.
  • We highly recommend adding root stimulator and fertiliser (only add half of the manufacturer’s recommended dose).
  • To avoid planting and nutrient issues you must check that the pH of the solution is adjusted to 6.
  • When the coconut substrate is fully rehydrated you may notice one side of the Slab is more hydrated than the other. This is normal.
  • Allow the Slab to rest so the high capillarity of coconut will distribute the humidity evenly.
  • Once the Slab is hydrated you are ready to introduce your plants.
  • Cut the remaining drainage holes in the base of the Slab, prior to cutting the top cubes.
  • On the top of the Slab, cut out the remaining hole for UGro Cube Rhiza to sit on.
  • Now place your plants (or Cubes) on top of the planting holes, on the top the Slab.
  • The roots will now spread across, allowing the plants to absorb the nutrients.
