Chiller-Ready, Tent-Ready, Cultivator Approved

With advanced Venturi circulation for powerful oxygenation and nutrient delivery, it's designed for maximum yields in a compact space WITHOUT the need for air-stones or pumps!

Industry Leading Product-Yields
Many of our Home, Professional, and Commercial growers have found 25-30% increases in yields on average once they get familiarized with our HydraMax systems. Overall, our RDWC systems provide dramatic decreases in pests and plant loss failures through plant disease. HydraMax allows for growers to efficiently monitor and adjust for their plants along their grow cycles, and our entire recirculation method allows for powerful oxygenation and nutrient delivery, helping create one of the industry leading systems available on the market!

4-Bucket Home VS. 4-Bucket Professional
While the HydraMax 4-Bucket Home system and the 4-Bucket Professional system are chiller ready, the 4-Bucket Professional system is meant for growers that need further customization, are looking to build out automated dosing and watering capabilities,  and for those that plan on scaling their systems up at a later date. The 4-Bucket Home system is one of our most affordable systems, and as such, is a stand alone system, and non-customizable.

This Recirculating Deep Water Culture System includes:

• Four 8-Gallon Buckets w/ legs
• 4 Lids w/ inspection port & cover
• 4 Venturi Circulators
• Complete Qwik-Lok Plumbing Assembly (all necessary hoses and connectors)
• 1 Heavy Duty Danner 9.5 Pump, 1 Pump stack
• Four 5.5" Root Halo snap-in media-less netpots, each with neoprene collar insert.
• 1-Year Warranty
• Recommended chiller is a 1/10HP unit (Chiller does not come with system).

✅ Featured here are the plants and healthy root development from just 7 out of the 8 tower sections on our newest 32-Plant Hydra Tower.

🥬 This vertical hydroponic garden helped grow an awesome spread of lettuces, basil, and flowers which took up over 12ft. of space when spread out on a couple of our conference tables - all grown in just over 1sq.ft. of space, with an estimate of .38 cents in utility costs per day.

What isn't shown? All the armfuls of basil and lettuce we told our staff to stop eating so we could get a few decent videos!! 😅

What happens when you remove grow media from the equation?

Root Halo & TetraBase support plants without media, they help reduce labor, are reuseable, and allow less restricted root development. Overall, these help with reducing overall pest, pH fluxuations, and disease issues.

Our growers love these media-less product and so will you. Reach out or visit our website to make the swap today.

Built different — on purpose.

HydraMax RDWC systems are designed to eliminate common points of failure found in traditional hydroponic setups. No epicenter, quick nutrient feeding and homogenization, Venturi-based circulation instead of airstones, and clean-in-place maintenance capability, growers can simplify operations and reduce downtime between cycles.

This is system design focused on consistency, scalability, and long-term performance.

Your plants are constantly giving you data — you just need the right system to read it.

In a closed-loop RDWC system, water use is driven by plant evapotranspiration. By tracking consumption over time, growers can identify early outcome trends and make informed adjustments long before harvest.

This isn't guesswork. It's measurable insight — built on real-world data from a 16-week RDWC case study.

Grow smarter. Manage risk earlier. Let the plants lead.

Stop throwing money away on disposable grow media.

We offer two innovative alternatives: Root Halo™, our media-less, snap-in netpot designed to simplify resets, reduce pest problems, and enable healthy root development -- and TetraBase™ an easy to use "forever media" that anchors in plants, is 100% reusable, and easy to clean - boasting similar benefits as Root Halo.

Less labor. Less waste. More control.

Real growers. Real results. 

From build quality to customer support to explosive growth rates—this is what happens when a system is engineered the right way.

When growers choose HydraMax, they don't just upgrade their system—they upgrade their entire operation. And most don't stop at one.

The most successful growers don't chase trends - they dial in systems that deliver the same results, grow after grow.

Consistency in water, nutrients, and oxygen is where real gains are made.

Airstones clog. Oxygen drops. Maintenance increases.

Less maintenance. Cleaner systems. Better growth.

Qwik-Loks are a true staple for us here at Hydra Unlimited. Not only do we have them throughout the HydraMax Systems (Home, Professional, and Commercial!), but we also use them for custom solutions. They can be used at the end of your drip tables, from your batch tanks, or wherever else you need to move water. With a 25 year successful track record these things are reliable where you need them most and removable to keep a clean facility.

Shared by @Green-Cult, one of our amazing distributors in Germany — this HydraMax 1-Bucket System is putting in the work.

We partnered with Green Cult to source a proper 230V pump, ensuring growers across the EU get the same reliable Venturi performance and RDWC efficiency our U.S. growers depend on.
