Current Culture Under Current



Current Culture Under Current


The Under Current® is the worlds first re-circulating Water Culture Hydroponic System featuring our Patented Sub-Current Culture® Method. This innovative application circulates literally hundreds of gallons of solution per hour beneath plant roots. The Under Current® supercharges the solution with dissolved oxygen, creating a hyper aerobic condition. An inline Danner Mag-Drive pump provides peripheral negative pressure by thrusting nutrients back to a return module (Epicenter). From this point the solution is drawn from module to subsequent module, evoking perpetual fluid motion. All Current Culture Systems now come with White ABS lids. These new white lids are made of durable ABS plastic, are UV stable, 100% non-translucent and highly reflective. New side-entry air ports on all Current Culture Under Current® system now include an innovative side-entry for the air diffuser lines utilizing a uni-seal for each module. This allows you to remove the entire module lid without disconnecting the air lines, making root-zone inspection much easier.

*You can get as crazy as you want with lighting combinations. With new technology like the Ceramic Metal Halides (cMH) or Light Emiting Ceramic(LED) [same technology, different name], Dounble Ended, or DE lighting and Hortilux, -bringing a new 600W Ceramic HPS to the market- combining bulbs and spectrum to fine tune your garden is always an option. However, we find a minimal spread for your lighting in relation to your canopy will help you find a baseline for the output of your garden.
