The first substantial substrate innovation in almost 50 years, HydraFiber® is an engineered, porous fiber substrate with extremely low bulk density. Selected as GameChanger of the Year in 2019 by Greenhouse Grower, HydraFiber is a proven performer and used by leading growers. Growers everywhere are choosing HydraFiber to improve the quality of their mixes. 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. HydraFiber is readily available, consistent, and made in the USA for easy and reliable shipping and delivery. Now in both bale and tower format, HydraFiber products can be processed with or without specialized equipment and have helped improve substrates for growers and blenders across North America. 

Brands: HydraFiber Ultra (available in five formulations, along with both bales & towers); HydraFiber EZ Blend - available in bales and tower form.


HydraFiber Product Introduction


  • HydraFiber Ultra
    HydraFiber Ultra is a highly porous, engineered-fiber substrate amendment that offers growers flexibility and cost savings. Highly compressed Ultra bales come in 5 fiber sizes; 95-cu. ft. towers are available for processing without specialized equipment....

  • HydraFiber Ultra is an engineered fiber substrate amendment with 98% total porosity, providing higher air space compared to other market-leading substrate components, while maintaining or even increasing container water-holding capacity. HydraFiber Ultra features extremely low bulk density of 1.4 lbs / cu ft. The material comes highly compressed in both bale and tower form, and is available in 5 different fiber sizes. The material creates a superior air-rich root zone environment that leads to proven differences including better water management, better root development and exceptional finished plant quality.
  • HydraFiber EZ Blend
    Engineered-fiber HydraFiber® EZ Blend substrate offers growers cost savings, reduced reliance on other raw materials and maximized root development. It’s the most efficient option for operations that pad mix or use a bale buster or ribbon blender....

  • Growers asked for a HydraFiber raw material that performs as well as the original HydraFiber Ultra, but did not require added machinery to the mix line. HydraFiber EZ Blend – a compressed raw material that can be used without specialized processing equipment ­– is now giving many more growers great relief from rising material, manpower and shipping costs while seeing better water management, better root development and exceptional finished plant quality. On the business side, additional benefits include locked-in pricing and just-in-time delivery so valuable space is used for growing and not storing raw materials. “Made in the USA” EZ Blend substrate is available year-round in 40-lb. bales and cost-effective, 95-cu.ft. towers.
