In DWC (Deep Water Culture or Direct Water Culture) Hydroponic Systems, plant roots grow suspended in a well oxygenated nutrient and water solution. With this soilless growing technique, “deep” means that the roots must be submerged deep in the water. Besides light, the water, nutrients, and oxygen provide the crop with everything it needs for optimal growth. 

Benefits of Deep Water Culture Systems:

There are many benefits of growing in a Deep Water Culture Hydroponic System. Plants grow faster, healthier, and with higher yields. Plant roots are always submerged in a nutrient solution so there is a continuous supply of nutrient that is being oxygenated at a constant rate. Individual plants are grown in individual containers, so each plant gets the benefits from the nutrients for itself.

Useful for:

Lettuce is one of the easier and faster crops to grow in a DWC grow kit and is a great one to start out with. Strawberries, Cucumbers, Peppers, Beans, and Tomatoes are other great choices and most can be grown year round. Some crops require vertical support, more pruning and more lighting than others.

How to Use DWC Kit:

A simple Deep Water Culture Setup can be created with hydroponic buckets. A net pot basket sits in a hole, in the lid of the bucket. Grow medium such as clay pebbles, are placed in the basket. Sturdier grow media, such as rocks or pebbles can help to keep plants growing upright. A nutrient and water solution are added to the individual bucket or central reservoir. The water level in the bucket should not reach the top of the net pot, but it should submerge the roots of the plant. The amount of oxygen the plant receives is a major factor in DWC systems and is what makes this technique successful. Since the plants' roots are in the water constantly, it is important to use air stones and an aquarium air pump to help oxygenate the water and nutrient solution. The air stones create bubbles and together they increase the dissolved oxygen content in the solution, which enables the plant to take in more of the nutrient solution.


The Deep Water Culture (DWC) System Grow Kit makes growing with hydroponics easy in four large 5-gallon square grow sites with 4” wide lip net pots. The super quiet air pump with 4 port manifold supplies air using separate lines to individual air stones in each grow site, providing oxygenated water for optimal root health and faster, healthier growth. Four grow buckets are connected to a common reservoir bucket making top-up and nutrient balancing easy. Easy setup with custom buckets, high quality 3/4" tub barb fittings with large rubber seals and high quality 3/4" tubing. Wide lip net pots provide greater stability as plant grows and increases in weight.

Q. What is the difference between Deep Water Culture kits with and without a central reservoir?

A. For systems without a central reservoir, you need to manually monitor the water and nutrient level and top off the solution in each bucket as it is consumed by the plant. These are standalone buckets since they do not share a water supply, but the air pump is centralized. You can have one, or many buckets. For systems connected to a central reservoir, the reservoir is filled with water and nutrients. As the plants consume the water and nutrient solution, the solution across all the connected buckets is drawn from the reservoir by the plant. The solution only needs to be added to the central reservoir.

Q. What is a Recirculating Deep Water Culture System?

A. In a Recirculating Deep Water Culture System water is actively pumped and circulated via a pump through the connected buckets from the central reservoir. The solution only needs to be added to the central reservoir. The pump ensures even and optimal distribution of nutrient solution to each bucket.
