🌿 Product Description
The Under Current® UCXL13 RDWC System is the industry gold standard for medium-less hydroponics. Built around a 13-gallon growth module with 30" plant spacing, this system harnesses the power of Recirculating Deep Water Culture (RDWC) to deliver record-setting yields and pristine plant health.
Developed and patented by Current Culture H2O, the Under Current® is recognized globally for producing superior fruits, flowers, and essential oil profiles. It uses negative water pressure to continuously circulate a highly oxygenated nutrient solution through the root zone—no timers required. The result: explosive root growth, consistent pH/EC levels, and uniform nutrient uptake 24/7.
Perfect for residential growers, professional cultivators, and commercial operations, the UCXL13 maximizes limited plant counts and is ideal for mother plants or mainline production.
