Circular hydroponic cultivation system

Water Supply System(MAGMA-1000 V2.0)

The water system is a system that controls the suitable root-zone environment of crops, and is a key device in the hydroponics system. During irrigation, the concentration of the water is automatically controlled according to the set concentration, and irrigation control technology based on time and radiation can supply the water when the crops need it.

Water supplier program

  • Store micro-weather environment data inside and outside the greenhouse.
  • In circulating hydroponics cultivation, when drainage discharged from greenhouses is supplied with raw water through a 3WAY valve, it is linked with a drainage recycling controller that can adjust each of the four types of drainage.
  • The irrigation start time can be set by sunrise and fixed time, and the irrigation start time is automatically changed according to the daily sunrise time.
  • By dividing the day into four or more cycles, the set values such as irrigation by cumulative insolation, minimum waiting time, and maximum waiting time can be changed for each cycle, optimally adjusting the balance of moisture and nutrients in the root area.
  • Set the quantity per time by selecting the quantity per time (minutes: seconds), per area, and per dripper.
  • EC/PH has upper and lower limits to ignore the sensor value when there is a sensor malfunction and supply positive amount with a proportional control random set value.
  • Depending on the solar radiation value, the set EC value can be decreased proportionally.
  • The irrigation setting value and the EC setting value by the solar radiation accumulation speed are automatically changed.
  • Data such as supplied irrigation quantity, EC value, PH value, number of times, and time are stored.
  • It shares solar radiation sensor values in connection with Magma Plus, a complex environment control system, and can be controlled and monitored on PC/mobile.
  • It is possible to select a positive liquid tank by cumulative insolation the previous day and supply positive liquid by accumulated insolation speed based on external environment data.
