What is the Under Current System? 

The Under Current system is the world’s only recirculating water culture hydroponic system to feature the patented Sub-Current Culture circulation method. The Under Current is cornerstone of the CCH2O Proven Production Approach when used with Cultured Solutions® Nutrients and the CCH2O Nutrient Dosing System. 

Sub-Current Culture (SCC) technology utilizes negative water pressure to recirculate highly oxygenated nutrient solution through the plant’s root zone. This continuous fluid motion supercharges the nutrients with dissolved oxygen, creating hyper-aerobic conditions perfect for explosive plant growth. 

Constant 24/7 nutrient circulation ensures pH and EC levels are uniform throughout the entire system. 

This unique water culture application is unprecedented in layout versatility and ease of use. The Under Current consistently delivers awe-inspiring yields for any sized application, from hobby to commercial greenhouse.

Accessories for your Current Culture UC Hydroponic System 

Grow confidently. With 10+ years of industry-leading innovation and results, we are the experts. 

Cultured Solutions nutrients are the best way to provide balanced nutrition in your hydroponics system to maximize your plant's vigor. The proven approach to successfully growing hydroponically. 

The following important tools will maximize your garden's production. 

Reverse Osmosis Water Filters 

Water quality is of the utmost importance when growing in water culture. RO water allows growers to control all minerals and nutrients their plant's uptake. A reverse osmosis water filter is recommended for source waters exceeding 100 ppm. 

Water Chillers 

The highest levels of dissolved oxygen are only accessible with cool root zone temperatures. High water temperatures limit the solutions ability to hold dissolved oxygen, while also providing the ideal environment for dangerous pathogens. Water chillers ensure cool, consistent solution temperatures are provided to the root zone. 

Meters & Testing 

Utilizing metering equipment in your garden will offer precise monitoring over essential environmental factors such as pH, ppm/EC, temperature and humidity. When used in conjunction with dosing and controlling equipment, the Under Current has the potential to be completely automated. 

Reservoirs 

Using a top-off reservoir will maintain accurate and essential solution levels throughout the course of the growing cycle, ensuring plants stay hydrated. 

Current Culture also has commercial cleaning products for both surface and air disinfection and sanitation. 

Current Culture Air Sanitation 

Indoor greenhouse air quality can have a huge impact on plant growth and final product yield. Humidity generated by the plant creates a perfect breeding environment for various airborne pathogens and fungal diseases like powdery mildew, downy mildew, and gray mold/botrytis. These microbes can easily spread throughout the greenhouse, putting your crops at constant risk. The best way to prevent an outbreak is to invest in air sanitation technology. 

Current Culture Surface Sanitation 

The Current Culture C1 Mobile Disinfection Cart is best when you require ozone disinfection in multiple locations within a facility, different buildings, larger facilities, or when you simply want the convenience of mobility. Professionals understand the benefits of ozone as a disinfection tool and a safe organic solution that can replace traditional or harsh chemicals. The Mobile Disinfection Cart uses ozone-enriched cold water supplied at the rate and concentration you desire.
