Deep water culture (DWC) is a method of growing that leaves your plant roots submerged in a highly oxygenated nutrient solution. This causes rapid growth and improves yields. The multi-pot IWS DWC can be fully tailored to suit your needs. There is a built-in timer so that you can control precisely when the system fills and empties. The IWS deep water culture system is manufactured from high grade recycled plastic. It enables you to create a simple set-up and is useful for all growers from novices to experts. The complete system with timer control, is versatile and requires little maintenance. Components come pre-drilled with an inspection hole in the lid so that checking your plants’ progress is much easier. You also have the ability to drain nutrient solutions back to the main reservoir, and pH and EC levels can be adjusted and maintained in one place, with no complications.
