The regulator shows the pressure of gas in the tank and the cubic feet per minute at which the gas is being released when the solenoid valve is opened. Evacuation! Injection Cycles There are a number of reasons that growers choose different lengths of time between cycles for the evacuation/injection process. The exhaust fan does a lot more than just change the air to eliminate CO2 depletion. Artificial lighting often causes a heat build-up. Periodically replacing the hot, stale air with cool, fresh air helps keep the heat within acceptable limits for white widow seeds . Also, plants transpire water through their leaves into the air during the growth process. This raises the humidity, which can also make the environment prone to mold and rot, as well as cause loose, stringy plant growth.
