In the last article, the lighting and temperature of your grow room climate control were covered.
Too much lighting, or too little, can hinder yield. Lighting also produces heat, which often leads growers to miss their 20-degree window. You should heat your grow room between 65- and 85-degrees Fahrenheit, but with the heat produced from lighting, you may only have to worry about cooling. The larger the operation, the less efficient small-scale cooling systems such as window air conditioning units become.
In this article, you’ll learn about the air flow, humidity, and carbon dioxide of your grow room.
Keep Air Moving
Proper air circulation is extremely important to your crop. Still or stagnant air can introduce mold, which can quickly kill your crop (not a situation you want to be in). Airflow can also help your plants grow stronger stems and branches. When your plants soak up the water through their roots, the water travels throughout the entire plant. The water that isn’t absorbed by the plant is evaporated via pores, just like the ones you have on your skin. The evaporated water hangs in the air that surrounds your plant. If it stays there, it’ll keep your plant too moist and cause mold and fungus build up. Sometimes all you need is to run a few fans, other times your solution may be more complex — especially if you’re using an air transfer system.
Air movement brings up humidity control, which is a huge aspect of climate control. The transpiration rate of your plants, which is the process of evaporation that was just mentioned, can be influenced via humidity control. Unfortunately, controlling the humidity in your grow room isn’t as easy as it sounds and is completely different than, say, the flood and drain hydroponics systems you might be using. Lower humidity levels, as in those under 20%, can actually stunt plant growth by depriving the plant of necessary hydration. Smaller operations might be able to get away with a residential dehumidifier could work just fine, but a larger operation might require the expertise of an experienced grower to help you get set up. You can look into commercial dehumidifiers to help you control humidity, but you’ll need to figure out how much humidity is required for your setup first.
Carbon Dioxide Levels
Because the necessary CO2 levels can vary depending on the other aspects of your climate control, CO2 is one of the nutrients that you consider as a part of climate control. Too much or too little CO2 can affect your plant growth just like any other nutrient, and things like time of day/night, and growth phase can dictate how much you need. Often, growers use compressed CO2 on a timed-release, while others are more sophisticated and rely on electronic sensors. You should always consider your CO2 as part of your climate control, as well as a supplement in flood and drain hydroponics.
Each grow room will be a little different depending on what the variables are, as well as the preferences of the grower. As a new grower, you should welcome the advice of seasoned growers and invite those with experience to help you set up your operation.
