About Us

Hydrodynamics International, the exclusive North American distributor for the popular Clonex line, was founded in 1997 as a joint venture with the UK based Growth Technology. HDI is always looking to introduce new products and in late 2012 released a new addition to the Clonex line, Clonex Mist. Clonex Mist is a foliar spray – containing natural ingredients and no hormones – with a demonstrable capacity to initiate and support dynamic rooting on stem cuttings.

In addition, HDI distributes the single-part Ionic nutrient line along with such products as Nitrozime, Fossil Fuel and GreenFuse. These additions have become a staple for many growers throughout the US. HDI also expanded the line of available propagation products by adding the bestselling Root Riot starter cubes. These products, in addition to others, have helped grow Hydrodynamics International into a well-recognized company that provides superior products to growers across North America.
