Under Current RDWC System Upgrades 2016

It’s hard to believe we’re approaching 10 years of offering the Under Current® RDWC system to growers around the world. Over the years we’ve made countless improvements in an effort to provide the best RDWC hydroponic system on the market. It’s our drive for excellence that fuels these continual improvements and keeps us moving forward.

We’re pleased to announce we’ve recently released some much anticipated Under Current® system upgrades. We invested much time and expense in R&D bringing these newly developed improvements to market and I’m certain growers will quickly see the advantages of these changes.

We assure you any changes we make to our products moving forward are in an effort to increase their effectiveness. Our constant drive to improve what we do has allowed us to continue expanding our product offerings and grow.

Thanks for your continued support.

CCH2O Lids in Whitecch2o-lid

All CCH2O lids are now available in bright white ABS material. This upgrade reduces absorption of heat into the nutrient solution, decreasing the cooling load on your chilling system. These new lids are:

o Highly Reflective
o UV Stable
o 100% Non-translucent (Does not allow light incursion.)
o Cooler Operating: reducing total BTU being absorbed
o No Visible Scale Build-up
o Same Durable ABS Construction

Aqua-Pore™ Side Entry KitsSide-Entry

We’ve recently changed all of our growth modules (8/13 gallon) to include a small hole in the upper lip; this allows the air hose to enter through the side. This upgrade allows growers to remove lids without having to disrupt aeration hose, making plant transitions much more seamless. Instructions have been updated to cover this modification.





Aqua-Pore™ AnchorsAqua-Pore-Anchor

Included with all Under Current systems, the Aqua-Pore Anchor replaces the large O-ring in the bulkhead nut. The Aqua-Pore Diffuser slips under the feet of the Aqua-Pore Anchor on both sides of the growth module and is “anchored” from movement or floating. The Aqua-Pore Anchor is available in 2″ and 3″ for all 8/13-gallon systems. **Suction cups will still be included in all Aqua-Pore Diffuser kits.


White Hose

White 3/4″ Return Hose: All 3/4″ ID hose leading from return manifold to Epicenter is now supplied in white. white-hoseThe lighter material will reduce absorption of heat into the nutrient solution, reducing the load on your chilling system. 100% Non-translucent.

White HDPE 1/4″ Aeration Hose: All 1/4″ ID airline running from chrome splitter to growth module is now supplied in durable, kink resistant High Density Poly Ethylene. Besides being supremely durable and long lasting, HDPE is a recyclable plastic and a more eco-friendly alternative to the FPVC hose we’d previously used. 100% Non-translucent.

White 3/4″ Aeration Hose: All 3/4″ ID hose leading from air pumps to chrome splitters is now supplied in white. The lighter material will reduce absorption of heat into the airline keeping air cooler before entering water. 100% Non-translucent.

Under Current® PRO Lids in Whitepro-lid-4

Any PRO systems or SOLO Pro units ordered with 4 or 6-site lids will now come standard in White. Epicenter lids will remain black for the time being until inventory on hand is exhausted. We’ll be transitioning all other sizes slowly throughout the year. The new white PRO lid features an Acrylic Korad cap which is UV enhanced to resist fading or discoloring for up to 10-years in high light/greenhouse environments. 100% Non-translucent.

Bulkhead now without O-rings

Please note we’ve excluded O-rings from all bulkheads sold in Under Current RDWC systems and a-la-carte. The removal of the O-ring now affords an easier installation as it reduces associated friction caused by the O-ring, which lead to occasional sealing issues. The removal of this O-ring allows installers to quickly tighten nuts on bulkheads with little to no need for follow up cinching. The exclusion of the O-ring does nothing to reduce effectiveness of seal. *Note: All sealing of our bulkheads occur outside the growth module with the large flat gasket.

Under Current Assembly Instructions Updatehydroponic-instructions

We’ve updated our Under Current Assembly Instructions to cover all of the changes mentioned above. The 2016 assembly instructions have also been reformatted and improved to make for easier system installation and operation. See our new Under Current Assembly Instructions here.
