RDWC or Recirculating Deep Water Culture, takes DWC Hydroponics to the next level. Consisting of a minimum of 2 grow containers and expandable to hundreds (in theory) RDWC Hydroponics systems have a central reservoir or control container, that is then filled with a Nutrient Solution and pumped out and into the other containers that are growing plants, before returning and the starting the cycle all over again. This has lots of advantages, the main one being that you can take care of multiple plants by only adding nutrients and testing water in one container. Perfect for a crop of Pepper Plants, Tomatoes, and other more thirsty fruit bearing plants. We stock a range of systems some of which are expandable, and all of which ship with everything you need to get growing out of the box. Just add Water, Nutrients, and your plant of choice!
