It can be tough on the quest to find the perfect thermometer/humidity monitor, especially if you don’t want to spend a pretty penny. I like this one. It only costs $8, and it comes with a probe. I have the probe hanging in my grow tent near the plants, with the screen outside the tent. This setup makes it easy to see the temperature and humidity exactly where the plants are without having to open the tent.
If you must get a heater to keep your plants warm, avoid letting it blow hot air directly on your plants, and especially avoid ever having it in the tent with your plants. You want a heater that radiates heat out evenly, instead of pushing out a blast of hot air like a space heater. Never allow hot air to blow directly on any part of the plant. Most heaters can turn on and off depending on the temperature, so they turn off when unneeded.
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.
7 Essential Concepts About Temperature Control
Once the air becomes too saturated with water, it tends to form dew or films of water over leaves, which leads to mildew and bud rot. Plants also tend to grow more slowly in very high humidity.
There are many tools available to help you control the temperature of your grow room.
A plant that is grown in relatively cold temps can survive, but it will never grow as fast or as well as a plant living in a good environment. Indoor plants tend to be much more susceptible to cold than outdoor grown plants.
Temperature & Humidity Adjustment Cheat Sheet
But did you know there’s a type of cannabis that will make buds even if you leave your grow lights on for 24 hours a day?
Well, ideal outdoor marijuana temperature is actually the same for any type of grow. It’s because indoors we simply try to recreate artificially the natural environment that cannabis plants have best adapted to. The only difference is that, in an indoor setup, we have more control in maintaining the perfect conditions. And they are:
Not sure if your climate supports outdoor cannabis growing? Find out how low temperature and cold weather affect your harvest
Important! When shopping for an outdoor photoperiod strain, take with a grain of salt the harvest times that a breeder promises. If, for example, they say late September, they probably mean places like Spain or Southern France, not Scotland or Denmark. The farther up north, the longer the summer days, and the later the flowering begins (and finishes). That’s a ‘perk’ of living at higher latitudes.
