Created for the specific needs of professional hydroponic growers, XL’s modified cell structure and unique chemistry
promote faster, stronger root growth. Specialized density and drainage properties in a fine-cell design provide uniform moisture throughout the substrate, whether overhead irrigation or subirrigation is used. This ensures nutrients are more readily available. Horticubes XL are available only with top grooving. Seeding options are also available for single and multi-seed sowings.
