Good marijuana is the result of a good growing environment, so the key to growing marijuana well is to create the optimal micro-climate for your plants to express the full potential of their genetics. How is this achieved? With a complete system for monitoring and controlling every aspect of climate within the confines of your grow room.
Hopefully, you’ve made the choice to cultivate in an enclosed grow room environment. This is advantageous for a variety of reasons, all of which can be summed up in one simple word: Control. By growing in a closed environment, you minimize all factors which are outside of your control, factors encompassed by the external environment, which even indoors is only somewhat controlled, and you thereby maximize the degree of control you have over your plants’ growing environment. The best way to do this is by purchasing a prefabricated, modular, air-tight and light-tight grow room enclosure. The best of these will come with everything you need, all systems included, but you can also purchase the enclosure and all of the other systems separately, and put them together yourself. Or, you can spend a little bit more money, skip all that hassle, and allow a professional grow room designer to design and install your custom grow room for you.
Whichever way you choose to go, the important thing is that you are growing in an enclosed environment. So, once you have separated your plants from the uncertainties and fluctuations of the external world, now the question remains, how best to regulate the internal environment? This is mainly a question of setting up a system of monitors and regulatory mechanisms for environmental control. We will go over these systems here briefly, to give you an idea of what you will need. If you’re going to set up this grow room yourself, ultimately much more research will be needed for each system, but this article should give you a good starting point for your journey.
Of course, the first thing that everyone knows is that you’re going to need your lights to be on a timer. These are simple enough, and can be programmed to whatever schedule you need for both your vegetative stage and flowering stage. It’s normally recommended that you grow your plants in their vegetative stage with less than 11 hours of darkness every night, and then it is critical that your plants get 12 hours of darkness every night of their flowering stage. This is basic grow 101 stuff, so we won’t spend much time covering it here.
Equally important to get right, but slightly more tricky, are your other environmental factors, primarily those that have to do with the air in your grow room. It’s important to keep a good balance of temperature, relative humidity (amount of humidity that is right for the temperature), and CO2 levels are the main things to be concerned with. Each of these factors is controlled by having a monitor, which consists of a thermometer, hygrometer, and CO2 meter, respectively, and then having those monitors connected to the appropriate regulators. These consist of a portable AC and possibly heating unit, depending on how cold you expect your grow room to get, a humidifier and dehumidifier, and a CO2 generator. The best way to connect the monitoring mechanism to the controlling or regulating mechanism is with a device called a climate controller, which can be purchased on the internet or at grow shops, and basically this ensures that your systems respond appropriately to the environmental conditions (that your heat comes on when it gets cold, that your dehumidifier comes on when it gets too humid, etc.).
Another Cannabis cultivation 101 factor is having your irrigation system on timers. Many of the higher end climate controllers will also manage this function, but irrigation timers are also relatively affordable and easy to find. One more thing that you may consider worthwhile to install is a flood detection monitor. Flooding is a common problem with indoor grows, and although it won’t do much to your plants, it can cause serious problems for your grow room and the space that your grow room is in. With this simple device, you can prevent flooding and help prevent unnecessary property damage.
Of course, if you choose to purchase a turnkey solution, such as a modular, prefabricated, enclosed indoor grow room, you will save yourself a lot of the trouble of setting up all of these systems yourself, because your grow room designer will install all these systems for you. Sure, it will cost more to have a professional do it, like most things, but also like most things, it will be professionally done, and unlike most things, your grow room will pay for itself and it’s installation within the first few harvests. It’s something to seriously consider. Either way, being aware of these factors will have you on your way to a top-notch, controlled grow room environment.
