 The Under Current® PRO is a Greenhouse Grade Re-Circulating Water Culture System made specifically for Commercial Growers.

The re-designed Under Current® PRO represents the largest, highest quality, most durable version of our Under Current® system to-date. With high levels of aeration and circulation, nutrient efficiency is maximized and yields are expected to be off the charts.

The 35 gallon Under Current® PRO systems function much like their 8 and 13 gallon counterparts but feature several unique and up-sized heavy duty components. Every element of the system has been reinforced and maximized for longevity in adverse greenhouse-style conditions.

Greenhouse Grade PRO Components

CCH20PRO Growth Module

The reinforced solid ABS PRO Growth Module features water level indicators, recessed bulkhead coves, an easy drain bottom, recessed drain valve cove, and custom inlets for our float valve and water inlet tee.

Made in California.

PRO Lids

The reinforced solid ABS PRO Lid allows growers to easily transfer plants from the 8 or 13 gallon systems by simply moving standard CCH2O lids and CCH2O Net Pots intact. The PRO Lid is also available in a 4-site, 6-site and 11-site version for tighter plant spacing and Sea of Green cultivation. All four PRO Lids incorporate dual port-hole access points and air inlet coves. Made in California.

CCH2O Under Current Pro Lids

CCH2O Pro Air DiffuserAqua-Pore PRO XL Air Diffusers

All PRO systems come standard with new Aqua-Pore PRO XL Air Diffusers. Aqua-Pore Pro Diffusers have low back pressure creating significantly higher oxygen transfer rates and higher dissolved oxygen (DO) levels. The membrane’s tiny pore size creates extremely small diameter bubbles. These new diffusers are more durable, have a long-life, require low-maintenance and feature a quick connect fitting for easy installation.

CCH2O PRO Air DiffuserPRO Air Delivery System

The PRO Air Delivery system includes the highest quality linear air pump or commercial regenerative blower (16-site and above). It comes standard with up-sized, quick-connect air manifold fittings and premium quality air hose.

Growing in the Under Current PRO

CCH2O Pro Plant

For commercial applications the Under Current® PRO triumphs in efficiency and yields. The PRO system offers growers the opportunity to fill very large spaces and grow massive plants without the extra work of managing multiple systems and reservoirs.

Having fewer larger systems equals higher productivity in terms of workflow, transplanting, maintenance and harvesting.

The Under Current® PRO system is best situated in either a greenhouse or indoors with a combination of vertical and horizontal lighting. The 35 gallon PRO growth module with single plant sites are best utilized on 70”+ plant centers.

Starting plants in an 8-gallon Under Current® system and transplanting them to the PRO module at a height of 3-4’ will yield a monstrous 8-10’+ finished plant when harvested.

For even more flexibility we offer interchangeable PRO Lids in 4, 6 and 11-site configurations. These durable ABS lids increase the PRO system’s versatility and allow for tighter plant spacing, quicker turnaround times and Sea of Green (S.O.G) style cultivation methods.
