It is assumed that you are using pressurised irrigation. Using HUMIC you can upgrade your irrigation system so that all your plants are irrigated automatically. You can leave your garden unattended for weeks on end. 

​

HUMIC does not need any electricity. Furthermore, it is a smart controller because the water usage is controlled by the prevailing weather conditions. In fact, the water usage (litres per week for example) is directly proportional to the net evaporation rate (that is, evaporation minus rainfall).

You can adjust the water usage by adjusting the control dripper. You can adjust the irrigation frequency by changing the float.
