Deep Water Culture (DWC) 4 Site 5-Gallon Hydroponic Grow System

$249.00 USD


The Deep Water Culture (DWC) 4 Site Hydroponic System 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.

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. The amount of oxygen the plant receives is a major factor in DWC systems and is what makes this technique successful. 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.


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.
