There is a big difference between doing something and doing it correctly. Anyone can grow a spider plant or some basil on their window sill. But professional growers who plan, execute, and document the process and results are going to wind up with a better crop every time.
When it comes to introducing CO2 into your greenhouse - either as a growth catalyst or as a fumigant - the same holds true because bad planning can not only be costly, but can be dangerous or even lethal.
The introduction of CO2 must be done in a precise, controlled, calculated, well planned manner. Simply opening a valve on a CO2 tank at one end of the room and hoping that the gas will disperse evenly is not a good plan.
Creating an intelligent design that fulfills the principles of the gases desired interaction with the plants can be tremendously effective. In addition to creating higher and better yields, an intelligently designed system can save you hundreds or even thousands of dollars in gas costs. Our customers report a 30-40% reduction in gas usage when they move to an intelligently designed system.
If you are getting into indoor greenhouse growing, find an experienced HVACR contractor to design a system for you. You may have to spend some time educating them on growing and the need for CO2, but their experience with precise air exchange rates can create a safe and effective system. Installing a system with correct CFM air flows, pressures, valves, and safety devices are critical to success.
For example, our aSense Indoor Greenhouse Wall Transmitter measures carbon dioxide and temperature in the air, then sends the readings to your climate control system. It can also be used as a stand-alone device to drive a exhaust fan or an air duct damper.
In addition, take the time to learn if your city or state has requirements for growers. Whether you are growing cannabis, mushrooms, or gladiolas doesn’t matter. There are now regulations regarding the storage and use of CO2 for indoor growers in many states and local municipalities. Do you need a monitor for safety? Does it have to have a strobe light? See this article for more information.
As Dave, a grower in Denver, told me recently, “Having the correct CO2 system is as important to me as the lights and even the plants. I might as well throw money down the drain without the right CO2 system.”
