Two happy vegetative plants getting a comfortable 75°F (24°C)
Although those are general guidelines, plants can thrive at different relative humidities depending on the temperature of the air.
For a lot of indoor growers, that is all you need to worry about. If it feels too hot or too cold for you in your grow area, it’s probably too hot or too cold for your cannabis plants as well.
Temperature and relative humidity (RH) are closely related to each other. Sometimes you can overcome a problem with one by fixing the other.
The main thing you must do as a grower to professionally dry and cure your buds is to maintain the proper temperature and humidity during the process. If you follow the right method, you never have to worry about mold or overdrying, and you will get beautifully cured buds every time.
You need to control both temperature and RH at the same time to get the best results when growing cannabis.
Change the Light Schedule: If you’re in a situation where the temperature is climbing too high at specific parts of the day, then you can change your light schedule so that your grow lights are off during the hottest part of the day. For example, in the vegetative stage, your plants need 18+ hours of light each day. If it gets too hot in the middle of the day, you could set your timer to turn your lights off for 6 hours during that part of the day. This strategy will not fix a major heat problem but can help alleviate symptoms of heat stress during a short hot spell or heatwave.
While starting with good genetics and properly caring for plants is key to growing top-shelf quality buds, your job isn’t over when you cut down your plants at harvest. I’d say that almost 50% of the final bud quality is determined after you cut down your plants, but how you choose to dry & cure your buds.
