What Is BubbleGen Hydroponic Nutrient Aerator?

BubbleGen uses a water pump to quietly oxygenate the nutrient reservoir without the need for noisy air pumps and air stones.

BubbleGen works on the simple principle of creating a pressure difference that draws atmospheric air through a filtered tube. The air is released as small bubbles, which mix with the water flow and percolate up through your reservoir to oxygenate the nutrient solution on the way.

Quiet Operation

The design of the BubbleGen includes an inbuilt silencer that works to reduce the noise produced. Water Pumps are much quieter than Air Compressors and Air Pumps. You'll hardly notice any noise from BubbleGen, just the gentle whirring of the bubbles.

Benefits of Using BubbleGen

The following list provides an overview of the list of benefits for using BubbleGen:

  • Does not add additional heat to the solution
  • Air can be drawn from wherever required
  • Saves cost and energy compared with Air Pumps, Circulation Pumps and Air Stones
  • Can operate with less than 1000LPH to over 4000LPH pumps
  • Supplied with three suction cups to secure mount to bottom of tank
  • Simple installation with only two connecting tubes

BubbleGen keeps your nutrient solution well mixed and oxygenated, extending the time the solution stays fresh. It provides your roots with the perfect mix of nutrients and oxygen, improving your results and helping to keep your plants healthy.

The output of the BubbleGen sends the energetic circulating stream of nutrient and bubbles in two separate directions, via 2x nozzles.

The BubbleGen completely replaces the need for a Circulation Pump, Air Pump and Air Stones. If you are currently using a Nutrient Chiller a single pump can be used to drive the BubbleGen.

No Air Stones to clog, break or rattle so it’s an easier system to use with less maintenance required, just set and forget, safely in the knowledge the BubbleGen will oxygenate and circulate your nutrient solution within your reservoir.

There's no moving parts or small diameters that could clog, so your BubbleGen will maintain performance over a long lifetime. We recommend cleaning your equipment between crops to avoid cross-contamination in the event of any grow room disease.

How Do I Use BubbleGen Nutrient Reservoir Aerator?

Garden tip: It's vital that you ensure the air intake of the BubbleGen remains above the water line at all times.

  1. 1. Attach the sucker feet of the unit to the bottom of your reservoir.
  2. 2. Secure the 1.5-metre air intake tube to the air filter and secure it outside the growing environment.
  3. 3. Attach the short length of hose to a suitable nutrient pump.
  4. 3. Apply power to the pump, and watch to see the nutrient solution mixing and bubbles bursting out of solution.

Garden tip: To avoid changing the chemical properties of your nutrient solution, secure BubbleGen's air intake outside the growing environment. Warm air will slowly increase the temperature of your nutrient solution. Air with high CO2 levels increases the acidity of the nutrient solution over time. BubbleGen is supplied with a 1.5-metres of 8 mm air intake hose. You can purchase as much additional 8 mm hose as you need to extend this. The 1.5-metre hose is enough to draw air from outside a small tent, you may need to extend this for a larger tent or room.
