The IWS deep water culture system combines deep water culture with flood & drain, giving you lush and rapid growth from the benefits of both techniques.
Each pot is connected to a brain bucket which drains and refills the nutrient solution as frequently as required (usually once or twice a day). The nutrient solution is taken from each 18L pot and fills the water barrel where it is mixed and then re-issued to each pot via the brain bucket. This ensures that all plants are exposed to the same pH and EC levels and means you only need to correct the pH or EC of the solution in the barrel rather than each pot. Although this does mean that you should only cultivate mono-crops in this system, unless you are sure that the different varieties you are cultivating have the same or very similar nutrient and pH requirements as well as similar finishing times. The kit is very easy to set up and simple to use meaning it is suitable for beginners and experts alike. Air pump, air-line and air stones are a necessity for the DWC side of this system, and are sold separately.
