This high-performance blend of washed and buffered coco fiber, pith, and husk delivers oxygen to plant roots while retaining moisture and nutrients, giving you more control over your fertigation regimen. The breathable fabric bag promotes air/gas exchange for increased root-zone oxygen levels, provides excellent water drainage for faster dry-down times, and encourages natural pruning and branching for a healthy root system.
