Buy now and receive a FREE quart of Veg A and Veg B nutrients by Cultured Solutions! The nutrient system designed by Current Culture to work with their Under Current Systems!
The Under Current is the worlds first re-circulating Water Culture Hydroponic System featuring our Patent Pending 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. Constant, 24/7 nutrient circulation ensures that pH and EC are uniform throughout the entire system. 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.

Do I need a top off reservoir?
Using a reservoir is not mandatory with the Under Current but is recommended for medium and large systems as more plants will use up more water, more often. Using a top off reservoir will allow you to maintain consistent water levels and follow weekly feeding schedules without dumping valuable nutrient solution. When optimized, a top off reservoir can be used like a doser for incremental EC/ppm adjustments and pH steering.
Do I need a water chiller?
The Under Current system operates well anywhere from 65-75 degrees F. We recommend maintaining a temperature between 68-72 degrees F. This is a happy medium between the optimum dissolved oxygen capacity without getting too cold and slowing the plants metabolism. If your ambient room temperature is above 75 degrees, a chiller is recommended and one can be easily adapted to the return pump on your Under Current system.
How long until I need to do a nutrient change-out?
In the Under Current, change outs should be necessary no sooner then 21-28 days. Many variables influence this time frame, so adjust your system as necessary. You should change your nutes once they destabilize or become murky. If your pH and ppm's are pretty constant, that is a good sign your system is healthy and you are using high quality nutrients.
What strength nutrients?
Simple question, not so simple answer. Depending on environment, genetics, quality of the nutrient, etc. your responses nutritionally should vary. Generically speaking we recommend half strength of normal usage directions on the bottle. More importantly we recommend sticking to base nutrients only, especially if you're new to deep water culture (DWC). If your nutes are worth their salt (pun intended) you should be blown away by the results you get. Any top shelf base nutes will provide all your plants need to thrive.
