Interested in creating a more sustainable high-yield grow environment and reducing water, nutrient, and labor costs to your canna or agricultural grows? 💧♻️ 🌎 

We actively R&D year-round and freely share the science behind hydroponic growing to make you successful; 🌿 Many factors can impact the plant's ability for evapotranspiration at their maximum capacity.  Both low and high air humidity impacts the process. Often measured as Vapor Pressure Deficit, VPD is related to air humidity and room temperature. Poor control of grow room atmospherics, such as VPD, can inhibit a plant's consumption of nutrients.  Day after day of poor room environmental control can add up.

Hydra Unlimited scientists and engineers use the concept of "Growth Index" – the calculation of total canopy volume in cubic meters to evaluate progress.  The amount of water released by the plants depends upon the total surface area of the leaves.  Think of it as a "green volume" in the room.  Hydra Unlimited's RDWC system is a closed loop system wherein 99% of the water consumed is consumed by the plants "green volume." Coupled with Hydra Unlimited's unique media-less cultivation options such as Root Halo and Tetrabase grow media (a breathable shield in which only 1% of the system water consumed is lost to system evaporation) both lost water consumption and HVAC load are dramatically reduced.  Further, there is neither a need for extra "water runoff" nor is there a risk of underwatering that is a part of any substrate farming practice.  This is why Hydra Unlimited offers world class minimum water and nutrient use with the potential of maximum yields while fully supporting Conservation Agriculture in the indoor space.
