solenoid valve is a valve which is controlled electronically. if there's electricity the valve will open. power off , valve off.
you need to attach it to a timer switch ( you can buy at ace) pwede ni i-dungan sa lightings nimo. since plants absorb co2 at daytime only. so maka save ka sa co2 nmo.dili applicable sa sugar yeast kay muboto ang bottle nmo. :P
