Get to the root of it with Artisun Technology’s Recirculating Deep Water Culture System! Our 4 site RDWC hydroponic system is easy to set up and provides everything needed to start growing on your own.

Recirculating deep water culture is a method used to cultivate plants with the roots submerged in a highly oxygenated nutrient rich solution.

Artisun Technology's RDWC systems are innovative and durable. They use a constant water level across 4 large grow sites and continuously re-circulate a highly oxygenated, nutrient-rich solution. This results in large, healthy plants. Roots will develop quickly and grow healthy, producing healthier plants and great yields.

Artisun Technology's undercurrent rdwc systems make it easy to monitor and maintain pH and EC levels from the central reservoir, saving time and effort.

Specifications of the RDWC Kit

Four 5 gallon grow buckets connected by 50mm PVC pipe to a reservoir unit with 5 gallon capacity. The system, uses an air pump to feed a large air stone in each grow site that provides oxygen directly to the water around the roots. The water pump circulates the oxygen-rich nutrient solution from the reservoir to each grow site, keeping the solution consistent at each site.

 Benefits of RDWC System :

  • Recirculating dwc systems improve plant health and accelerate cultivation rates and yield potential by providing plants with easy access to water, oxygen, and supplements.
  • Oxygenated water enables the plant roots to absorb supplements more efficiently, increasing plant growth rate substantially.
  • Evenly distributing nutrients to each connected growing site and maintaining consistent solution levels across all sites.
  • The constant flow of water helps to prevent algae, bacteria, and fungi from growing, while also keeping plant roots clean and free from infection.

Best solution on the market

Has everything needed for a RDWC kit. Nothing arrived damaged. I bought this because my home made attempt leaked and i didn't want to deal with further leaks. This has not leaked after a few days, the included hardware to tighten the pvc connections give me confidence that it wont leak. I like that the air pump has a dial so i can try to keep the noise down (and the airflow). 5 stars.

4 Bucket RDWC system.

Pros: Packaged fairly well, everything is black and light proof including the air hoses, All holes are cut very precisely and perfectly spaced (this ALONE makes this kit worth the $), high quality pumps, almost everything included, large PVC pipes w/ quality bulk heads and ZERO water leaks. The price is good for what you get too. You must remember this is food grade plastic which is very light proof. Cons: No instructions whatsoever, the lids need to have the security lid carefully trimmed off, FAQ says "2 days handling, 3-5 days ship time"- it took almost 2 weeks to receive this & shipping was nearly $60, the clay pellets were placed in flimsy zip-lock bags which partially opened during shipping, the level tube is too high and the net pots are in the water (there is supposed to be a gap between the water level and bottom of net pot once the plants have grown past seedling stage. The supplied PVC needs to be cut down and something adjustable threaded on), the drain hose supplied is too short & IMO it would be nice if there were spots to put strings for low stress training (I don't want to drill holes.)
