Description

Tight on space? All the same great features as our 4 site RDWC system…in a smaller footprint. Our 2 grow site RDWC system fits a 3' x 3' or 2' x 4' tent.

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.

Two 5-gallon grow sites connected by 50mm PVC pipe to a shared reservoir with 5-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.

Easily expands to a 4 site system using our:

  • how does rdwc workDid you know? 
  • RDWC systems grow healthier plants with greater yield potential 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
  • 5 stars: 3 (75%)

  • 2 stars: 0 (0%)

Editing previous review

I previously gave their two bucket system a bad review. After some fantastic customer service I have to change my review to a five star.
Thank you Karl for all of your assistance in helping me.

Not happy

I received my two bucket system, and when I went to inspect the contents I was unable to due to the bucket that has most of the parts the lid is locked, and I’m unable to open it. The lid that’s locked isn’t even on the correct bucket. I’m not happy at all.

Solid DWC system with plumbing that instills confidence

Disclaimer: I have NOT performed a grow in this system. This is based on a 3 day test. With experience in bucket DWC I can confidently say the design is solid without one(although seeds are germinating because I bought this to use it not review it).

With a robust air pump, premium airline tubing(Unkinkable. Not vinyl.), and extra large air stones, it produces a large amount of bubbles. I was extra impressed with the air-stones. They are about the size of a small can of red bull. Very nice and stand up on their own in the center of the buckets. The plumbing fittings are all 2ish inch PVC with nice rubber gaskets. They all thread together and tighten with an included giant spark plug wrench looking device. It all went together pretty easily with the included instructions. I did not understand what or how the water level control spout worked. It was not really clearly defined but it makes sure your plant buckets are always at the level of that spot while allowing it to deplete the water in the reservoir almost entirely. Just install it per the instructions and it will make perfect sense within 60 seconds of firing the system up. They include a second pump and hose to use to siphon water out of the reservoir. I personally own and use a fuel transfer pump that uses D Cell batteries. The nice thing is this extra pump is identical to the main system pump. Having a backup is fantastic.

Two items I think could be improved. The directions state the pump needs to be left on top of the the reservoir. This is kind of a pain as you need to move it to access the reservoir. My assumption, is this is to raise the pump above the water level to prevent water from gravity back-feeding into the air pump during a power failure. A simple solution to this is a standard aquarium airline check valve designed for this very purpose. One on each outgoing airline and water cannot back-feed as the valves are one way. This is a very cheap safety item for electric air pumps that's well worth your investment if not just including in the kit. With that upgrade there is no reason your air pump can't sit anywhere you want, above below but probably not in the buckets. The other item is minor but opening the first bucket lid(the res lid) was diffucult. I actually damaged the lid a bit but it's still functional. Be careful of this. I assume the same will happen to the grow buckets but I will be prepared. Once the lids are snapped on to them they are gasket sealed. These appear to be food grade buckets.

I would definitely buy this kit again. In fact, if this doesn't fill my tent out this grow, I will buy the 2 bucket expansion kit.

Great RDWC System

Super easy to setup. Took me 30 mins max. My ladies are growing great. Only issue I had was the air pump did not work. I suggest maybe switching to a reliable air pump. Overall a great system.
