MagniMoist doesn’t let water escape from your basket until your plant is completely hydrated. When you water, MagniMoist’s smart natural fibers deflects water back into the dry soil above it. Then when the soil is fully saturated, the fiber becomes porous and releases only the excess water. Proven to outperform old fashioned coco liners. 40″ x 60″ Sheet is easy to cut to line any size/shape basket, window box, topiary or specialty planter.
