Hi, It may be a silly question, but I am not really sure why would we use a solenoid valve, apart from saving on CO2.
If the plants consume CO2 during the day and release it at night, by constantly pumping CO2 into the tank wouldn't that ensure that there is always enough CO2 on the water for the plants?
