Grodan’s Gro-Wool If you’re growing thirsty plants in containers, then Gro-Wool is the product for you. Houseplants supported in Gro-Wool only need water once every two to four weeks.

When growing in clay pellets, mix in some Gro-Wool to make water and nutrient distribution more uniform (which also creates a moisture buffer, in case the pump fails). Since Gro-Wool is loose and light, it also promotes fine root (feeder root) growth, leading to larger, more vigorous plants. For more information, visit your local indoor gardening retail shop.
