rush r-dwc system

With up to 34 nutrient circulations per hour, no timer to manage and little media used, Rush R-DWC takes Deep Water Culture growing to the next level. 

The Rush R-DWC system is a combination of simplicity and top-end components, resulting in spectacular growth and huge yields.

My favourite Nutriculture grow system is the Rush as I love that it is a recirculating system and it’s great for experienced growers

Born 2 Bud


DWC with the added benefit of constant, rapid re-circulation!

Airstones in each of the Rush DWC reservoirs create a constant bubbling directly beneath each plant. This highly oxygenated environment results in exceptionally fast root growth. The nutrient solution in each chamber is constantly and rapidly recirculated between the reservoirs so the pH and water levels stay balanced.    

The Rush truly is a next level hydroponic system that delivers results time after time.

This re-circulating Deep Water Culture method of growing allows plants to feed as much as they need, whenever they need it, preventing over and under-watering.

Deep Water Culture is rapidly becoming the preferred method of growing for more and more growers across the world, with Rush leading the way in re-circulating Deep Water Culture systems.

why they are great

Perfect for growers who want to:

  1. Use the most advanced R-DWC method
  2. Maximise oxygen uptake
  3. Use little media on a large scale grow
  4. Easily maintain stable pH and EC on a large scale grow
  5. Turn plants under lights

hints and tips

Pump – leave the pump on 24/7 – the  roots need constant access to nutrient solution and oxygen.

Reservoir maintenance – Close off the piping at either end of the tank you want to clean with the stoppers provided. This allows plants to continue to be fed while maintenance is carried out on another reservoir

Water temperature – To maintain the temperature of the nutrient solution Rush can be connected to chiller. The ideal temperature is from 18-21oC.

Water levels – Rush has a unique adjustable float valve to maintain water levels.

When water levels need to be higher for shorter roots, adjust the float valve upwards. When the roots are longer, push the float valve down, so the roots are less covered by nutrient solution and have even more access to oxygen.
