Testers & Monitoring
Categories Testers & Monitoring
The thermometer is one of the most important instruments for indoor cultivation. With some lamps, the heat radiation is very high, thus the temperature must be controlled strictly.
With a hygrometer the humidity in a confined space can be measured.
Plants have very different needs concerning this. Some need very high humidity, others do not like that at all.
By using a hygrometer can determine the humidty and then, by changing the ventilation and possibly the irrigation, you can adjust it.
pH-Meters indicate the pH-Value. Strange isnt it? More simply, a pH Tester tells you if your substrate is acidic or basic and allows you to take corrective steps.
The electrical conductivity indicates whether the plants get enough nutrients. If it is too low, the supply of fertilisers must be adjusted.
