Growing water hungry plants in containers? Then Gro-Wool is a welcome addition to the mix. Gro-Wool can support house plants while watering just once every 2 to 4 weeks.
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 in your plants!
