How to Grow Cannabis in a Humid Climate

To understand how to grow cannabis in a truly humid climate, we first need to take a look at what the optimal climate for cannabis truly is.

Here’s the thing.

The cannabis industry is getting bigger by the day and it’s gaining legalized status in more states every year. This means that more and more people are going to be able to grow it legally, for personal use, as time goes on. But here’s another thing to consider.

Not every climate is the same


Obviously, different strains will tend to react differently to different environments.

Note: Day strains are really popular right now! But the question bears asking.

What can you do to grow cannabis in a truly humid climate, especially if that climate is so humid that it’s otherwise not necessarily a good fit for growing?

In this post, you’re going to learn everything you need to know.  Let’s dive into it.

Getting Started – Optimal Conditions For Growing Cannabis

Cannabis plants tend to do their best in a temperate climate. They fare well in a temperate range of 68 to 77 degrees Fahrenheit—though they prefer a slightly warmer range (up to 85 degrees) when flowering. Going along with this, pot plants tend to fare the best in a state of relative humidity, ranging somewhere from 40% to 70%.

The problem with too much humidity is that it can lead to problems like mold, disease, and fungus. And of course—if the climate is too dry, it can lead to drying out the plant and ruining your yield.

Professional growers generally use a hygrometer to determine the humidity levels in their grow rooms. They also use humidifiers, dehumidifiers, fans, and watering systems to help them achieve the perfect humidity for their particular strain.

How To Grow Cannabis In A Humid Climate


Obviously, the best way to grow cannabis in a humid climate is to control the climate by growing either in some kind of greenhouse (though you need to be careful about the temperature) or in an indoor, environmentally controlled facility where you can control the temperature and humidity at will.

With that being said, there are also steps that you can take to prevent humidity problems when growing outdoors as well.

How To Grow Cannabis Outdoors In A Humid Climate

One method for helping to protect your plants from the dangers of high humidity is increased ventilation.  This will help to keep mold and fungus from growing—and may help you to keep your crop healthy.  Now, small fans will only be of so much use here.

You may need to go all the way and install inline fans with filters to increase airflow.  This is kind of expensive outdoors. But it’s better than losing your crop. You can also prune your plants as they grow to help increase natural levels of ventilation.

When you remove superfluous branches, more air will be allowed to flow throughout the leaves—and that’ll help to prevent mold and fungus.  You can also take steps to keep your plants healthy even at the earliest stages of growth.

Some growers, for example, soak their cannabis seeds in solutions to help protect them and give them a healthy early start in humid soil.

Harvesting Cannabis In A Humid Climate

Harvesting is a crucial time for the health of your buds.  You’ll want to make sure that you ‘wet trim’ them. This will help to keep them from soaking in too much moisture in wet climates.

Wet trimming is a great practice in humid climates because, with less foliage attached to the flowers, drying will happen more quickly.  And this is definitely a good thing.  Wet trimming can be a bit of a mess. Trichomes will get on your fingers, and will basically be a sticky mess that’ll stick to everything.  But—if it protects the yield, then it’s more than worth it.


There you have it.  Everything you need to know about how to grow cannabis in a humid climate without losing valuable bud to disease, mold, or mildew. Remember, this sort of thing requires research and practice. So the more you learn before you give it a try, the better.  Consider watching some YouTube videos to help you get the hang of it before giving it a go yourself.  You’ve got this! You can do it.
