Golf Ball Airstone (a.k.a. Blue Economy Airstone): 1.5 - 5 Litres per minute of air flow needed.
To find out which air pump you need, see the 'How to Use' tab.
If you have an air flow rate of more than 5 litres a minute running through each one, the Golf Ball will end up being overdriven (see the video above!) You’ll need a Ceramic Disc or Coke Can Air Stone.
The hotter your nutrient solution, the lower the dissolved oxygen content. The ideal temperature for your nutrient solution is 18oC - 21oC. You can use a heater, chiller and thermometer to control your feed’s temperature.
- The Science
Why roots need oxygen
To survive and thrive, plants need a constant supply of oxygen in their root zone to:
• Boost nutrient uptake
• Help prevent Pythium
• Improves water absorption
• Enhance cell growth/activity
It’s one of the reasons why plants grown in bubblers thrive.
Oxygen in the root zone also prevents your nutrient solution from stagnating. This, in turn, helps prevent root problems, such as Pythium!
If there’s not enough oxygen
Plants will no longer be able to take up as much water through the roots.
They will have a limited access to vital minerals, and they won’t grow as much. Root development will be poor and plants will become stressed.
As a result, plants can experience deficiencies. In extreme cases, toxins will build up in the root zone, and Pythium can take hold.
How temperature affects oxygen levels
The hotter your nutrient solution, the lower the dissolved oxygen content.
The ideal temperature for your nutrient solution is 18oC - 20oC.
To control your feed’s temperature, we recommend using:
• A heater
• A chiller
• A thermometer
- How to Use
• You can suspend your air stone, or let it to sit at the bottom of your tank
• You can use it in a tanks with a volume of up to 20 – 30 litres.
Recommended Air Flow
• Make sure that you have an air flow rate of 1.5 Litres - 5 Litres per minute running through each stone. If you have an air flow rate that's greater than this, upgrade to a Ceramic Disc or Coke Can Air Stone.
Which Air Pump Do You Need?
You need one piece of air line for each stone. If running multiple air stones from one pump, you will need a manifold.
