Instructions
Cleaning The Emitters
O2 Grow Emitters will require cleaning from time to time. Over time, the Emitter may get a calcium build up from the water. A quick rinse in muriatic acid will remove the build up from the screens. Properly maintaining your screens will prolong the life of the Emitter.
Watering crops is the most important job in nursery production. Elevating dissolved oxygen levels in the water increases root efficiency.
Soil
When watering plants in soil, you will want to oxygenate your nutrient water just before pouring on plants.
Wicking
For wicking systems, you will want to oxygenate your nutrient water on a schedule. Use a timer to boost oxygen every 3-4 hours.
Ebb & Flow
In Ebb & Flow systems, it is best to oxygenate the nutrient water on a schedule. Set your timer to oxygenate just prior to flooding the tray.
Deep Water Culture
In Deep Water Culture systems, you will want to oxygenate your nutrient water on a schedule. Use a timer to boost your oxygen every 3-4 hours.
Drip / Top-Water
In Drip or Top Water systems, it is best to oxygenate the nutrient water just prior to your scheduled watering.
Aeroponic / Cloner
For Aeroponic or Cloner systems, you will want to oxygenate your nutrient water on a schedule. Use a timer to boost oxygen every 3-4 hours.
Top Questions:
In a recirculating DWC system, could you just use an emitter in the epicenter?
A: When it comes to DWC, you will want to calculate the total number of gallons/liters. For example, if your total system is 60 gallons, it would be recommended to use an O2 Grow 2120 unit to achieve the appropriate oxygen levels. Place the emitters into the epicenter and set them up to run on a timer for about 60 minutes on and 3 hours off continuously.
What DO levels should I expect?
A: A DO measurement of 10ppm or higher is ideal and should be achievable in most systems. Please take into consideration how your system is designed, when running the emitters in DWC, there are many factors that come into play like: water source (RO, tap, well water), water temperature, EC and TDS. Also consider if you are running stand alone DWC or recirculating DWC. There are some RDWC systems that have quite a bit of rushing water and that can sometimes lower DO.
How can I tell what my DO levels are?
A: The only way to really know what your DO levels are, is to purchase a DO meter. A decent DO meter will help you to dial in your nutrients as well. Having too much nutrient in your water can impede uptake by the plants and nutrients will become locked out. Locate an inexpensive DO meter to start, we can recommend the AZ 8403 (found in Google search). The instructions are very good and the website has some nice tutorials. Each unit comes with replacement heads and solution. If you can’t get the DO over 8 ppm in your DWC system with our O2 Grow unit, you probably have too much nutrient in your water. The water is simply too saturated with minerals to except any more oxygen.
