HYDRO POWER
Yes , you can run your hydroponic system on hydro power ; that is , if you have access to a source of running water on your property . In a nutshell , a portion of the flowing water gets diverted into a pipe ( a process also known as conveyance ) where it is delivered to a pump or waterwheel . This then converts the flow of the water into rotational energy . An alternator or generator then converts the rotational energy into electrical current . This system could be modified to run on stored water from a reservoir , but most hydro power systems take advantage of the natural flow of a body of water . The initial investment will vary greatly depending on both the distance from the water source and how many kilowatts ( kW ) the system will generate . Many farm-based systems can produce up to 100kW , but even a modest 10kW is more than adequate to power a small growing operation .
GEOTHERMAL
Using geothermal energy in your hydroponic system is not as common as using solar , wind , or hydro energies , but it is still worth considering . If you are already paying for the energy it takes to heat your growroom , or are in the position of building a new hydroponics system , it pays to employ geothermal heating if you can . Basically , geothermal heating takes advantage of underground soil or water temperatures . It draws this heat up from the ground into your structure and greatly reduces the amount of supplemental energy need to heat or cool the space around it .
