4-Site XL 7.9 Gallon Recirculating Deep Water Culture (RDWC) Hydroponic System

Got larger plants? Our latest 4-grow site RDWC hydroponic grow system super-sized! This XL Recirculating Deep Water Culture System is now available with 7.9 gallon grow sites and reservoir, and still fits a 4'x4' or 5'x5' space. 

In a Recirculating Deep Water Culture (RDWC) System, water is actively pumped and circulated via a pump through the connected buckets from the central reservoir. The roots of the plants are continuously submerged in a nutrient and oxygen-rich water solution growing healthier plants with greater yields, in less time.

Four 7.9-gallon grow sites connected by 50mm PVC pipe to a shared reservoir with 7.9 gallon capacity. The system uses an air pump to feed a large air stone in each grow site that provides oxygen directly to the water around the plant's roots. The water pump circulates the oxygen-rich nutrient solution from the reservoir to each grow site, keeping the nutrient solution constantly mixed and evenly distributed across each grow site. No need to top up each grow site individually, simply top up the reservoir as needed. No additional tools required.

 Did you know?

• RDWC systems grow healthier plants with greater yields, in less time by providing plants with continuous access to water, oxygen, and nutrients
• Oxygenated water enables the plant roots to absorb nutrients more efficiently, increasing plant growth rate substantially
• Nutrients are evenly distributed to each connected grow site and maintain a consistent level across all grow sites
• The constant flow of water helps prevent algae, bacteria, and fungi from growing, while also keeping plant roots clean and healthy
• RDWC systems are relatively low maintenance; Check nutrient solution often and top up the as needed through the central reservoir; change the solution in the reservoir every one or two weeks

FAQs

Q: What size footprint is the system?

A: Artisun Technology's 4 Site RDWC System is designed to fit into a 4’x4’ or 5'x5' footprint. The Overall size is 39" wide by 43" deep

Q: How frequently should you add nutrient solution to an RDWC System?

A: The reservoir level should be checked daily and topped up when needed. The nutrient solution consumption rate of the plants will depend upon the type, size and growth phase of the plants.

 Q: How frequently should you change the nutrient solution in an RDWC System?

A: The nutrient solution should be drained and replenished every 1-2 weeks depending upon on the type and size of the plants.
