For hobby or small scale growers
Optimise crop performance with consistent, accurate management of nutrient feeding by using the Bluelab Dosetronic Solenoid Kit - the simple solution for automatic feeding systems.
The Bluelab Dosetronic Solenoid Kit provides you with everything you need to set up an accurate, easy to manage, automated nutrient management system. The Bluelab Dosetronic keeps tight control of your vital nutrient solution levels automatically so you have the freedom to tend to the daily needs of your crop.
This kit has been specially designed for hobby or small scale growers and includes the Bluelab Dostronic Controller and Bluelab Dosetronic Solenoid Cable Pack.
For commercial or large scale growers please see our Bluelab Dosetronic Peridoser Kit.
How does the Bluelab Dosetronic Controller work?

The Dosetronic provides continuous control of the desired levels of nutrient and temperature.
All you do is program the required levels of conductivity, pH and temperature as the crop progresses through each growing phase. You retain control and the Dosetronic backs you up! This enables fast and accurate alterations to the feed system as the needs of the crop change.
The Dosetronic can be used for a wide range of applications including Hydroponics, Horticulture, Agriculture, Floriculture and Aquaculture and is ideally suited for re-circulating hydroponic NFT systems.
Automated and accurate nutrient control
The Bluelab Dosetronic Controller provides continuous control of conductivity, temperature and pH levels of a solution by adding fertiliser and pH corrector into your mixing tank via solenoids.
Simply program the Bluelab Dosetronic Controller with the conductivity, temperature and pH values that you want your system to run at and tailor the dosing intervals to suit the size of your mixing tank. The Dosetronic will then take care of the hard work for you.
By using high performance conductivity and pH probes, the Bluelab Dosetronic Controller will intelligently control the strength of your re-circulating solution to a high level of accuracy. When it detects that the conductivity or pH levels have fallen outside of your pre-programmed set points, the Bluelab Dosetronic Controller will automatically trigger the dosing of more nutrient or pH corrector until those levels have stabilised. The job of the Dosetronic does not stop there. It will tirelessly control your system 24 hours a day, 7 days a week, 12 months a year.
Solution or air temperature control
The innovative design of the Dosetronic means you can choose to control either the nutrient solution temperature, or the air temperature, depending on which is more critical to your growing environment.
All you do is select the heating or cooling equipment required to control the temperature of the air or solution, program in the temperature settings you require, and plug the equipment into the controller. You then place the temperature probe (supplied with the Dosetronic) where control is required.
The Dosetronic has proven itself in the hydroponic market worldwide for over 20 years and has earned itself an international reputation for excellence. This is why so many commercial growers are using the Bluelab Dosetronic to save time, money and improve accuracy.
It is one of the most simple, robust and reliable controllers in its class!
Solenoid dosing system
Three Bluelab Solenoids are supplied in this kit.
Each solenoid is supplied with a flow restrictor to reduce the flow rate for dosing into small tanks. This ensures each dose will not change the conductivity or pH by more than 0.1 EC or 0.1 pH, which avoids the risk of overdosing.
Each solenoid is able to dose up to 50ml/min if the flow restrictiors are removed.
