THE ULTIMATE GROWING MEDIA SUBSTRATE
The first substantial substrate innovation in almost 45 years, HydraFiber® is an approximately 98% porous fiber substrate with extremely low bulk density. HydraFiber is manufactured with our unique Thermally Refined® process that combines wood and bark and refines them in a pressurized vessel to create singulated, small-diameter, long, thin strands with large surface area (U.S. patent 10,266,457 and patents pending). With quality control and quality assurance checks every 30 minutes during production, HydraFiber is the same 365/24/7.
