We have a selection of Deep Water Culture systems available that will enable you to achieve unbeatable results in limited spaces. All you need is a handful of clay pebbles and the plants. Thanks to the innovative technology used, your plants' roots can easily absorb the nutrient solution for strong growth. We would strongly recommend using a water chiller for RDWC systems with four or more pots to keep the water temperatures between 17 -20 degrees C for optimum oxygen level in the root zone. The systems are durable, user-friendly, and ensure excellent grow conditions for massive yields.
