If you’re growing water hungry plants in containers then Gro-Wool is a good idea.  Gro-Wool can support house plants while watering just once every 2 to 4 weeks.  When growing in clay pellets mix in Gro-Wool to make water and nutrient distribution more uniform and have a moisture buffer in case the pump fails. Gro-Wool also promotes fine root growth which leads to larger more vigorous growth.

TIP: If you are using a drain-to-waste system, then you do not need to pH condition the Gro-wool. Just fully saturate the wool with a pH 5.5 nutrient solution.

  • On its own as a potting mix.
  • Mix with any potting mix to improve aeration and water holding capacity.
  • Mix water Gro-Wool into your sandy garden soil to improve water holding capacity.
