IWS Oxypot Kit - Simple Deep Water Culture Bubbler System
Best for: growers who want to try deep water culture (DWC) with a simple, single-pot bubbler system rather than a full multi-pot recirculating setup.
Our thoughts
The "Bubbler" nickname says it all, this is about as simple as hydro gets: a pot, an air pump, and bubbles doing the work of oxygenating the root zone. It's a great, low-cost way to see what DWC growth rates look like before committing to a bigger system.
The IWS Oxypot Kit, commonly known as a "Bubbler," is a single-pot deep water culture system that uses an air pump to force air through an airstone sitting in the nutrient reservoir. The rising bubbles oxygenate the nutrient solution, and as they reach the surface and pop, they create a fine spray that keeps the clay pebbles above the waterline moist, feeding the upper root zone as well as the submerged roots below.
This kit includes everything needed to get started: an air pump, air line tubing and an airstone, alongside the pot itself. It's a refined version of the classic bubbler design, with a few improvements over earlier models that make accessing the nutrient reservoir and topping up feed a little easier.
How it compares
Oxypot sits at the simple, single-pot end of the DWC category, rather than the larger multi-bucket recirculating systems.
- Versus Current Culture Under Current: Under Current systems recirculate nutrient solution between multiple linked buckets for larger grows, while Oxypot is a standalone single-pot unit for one plant at a time.
- Versus Alien DWC-style bucket kits: both are single-pot bubbler designs at a similar entry price point, with Oxypot's refined lid design making reservoir access easier.
- Versus a standard hand-watered soil or coco pot: DWC growth rates are typically faster thanks to the constant oxygen supply, but at the cost of needing a reliable air pump running continuously.
A genuinely simple way into hydro growing, without the complexity or cost of a full recirculating multi-pot system.
Usage guidance
DWC is simple in principle, but a few basics matter for good results.
Setting up
Fill the reservoir with nutrient solution, position the airstone at the base, and run the air pump continuously so bubbles keep the solution oxygenated at all times.
Reservoir top-ups
Check and top up the nutrient level regularly, since a single pot without recirculation will need more frequent monitoring than a linked multi-bucket system.
Root health
Keep the air pump running around the clock, since interrupted airflow in a DWC system can starve roots of oxygen far faster than in soil or coco.

Who this is for
- New growers wanting to try DWC without committing to a bigger multi-pot system
- Growers with space for one or two pots rather than a full recirculating room
- Anyone who likes the simplicity of a self-contained, single-plant hydro system
- Not intended for growers wanting a linked multi-pot recirculating setup
Our take
Works consistently without overcomplicating your feeding schedule, and it's a genuinely accessible entry point into hydro growing for anyone curious about DWC.
One we sell a lot of for new growers.
