You will benefit, though, if you do have an inline ventilation kit. Especially, when it comes to controlling heat and humidity. An inline ventilation kit will help you move the air in and out as needed.
This is one of those problems that would have to be solved case by case as every situation is different. Since you are using a grow tent, the benefit you have over a grow room is you are portable. Move the tent to the coolest part of your home.
If you let the humidity level get to high, you run the risk of condensation building up in the tent. You could also end up with mold which you don’t want.
When it comes to growing marijuana, I think a lot of new growers are mostly concerned with the soil and the required lighting. More-so, probably the lighting. If you really are interested in maximizing the amount of buds you get to harvest, then learning about temperatures and humidity requirements for growing marijuana is important.
It is okay to have lower humidity close to the 40% level during the flowering stage. 40% is not dangerously low, but low enough to benefit your plants.
So, what is the ideal temperature and humidity for growing marijuana in a grow tent? The ideal temperature for the vegetative (growth) stage is between 20 Celsius and 30 Celsius (68F to 86F). The ideal temperature for the flowering (budding) stage is 20 to 25 Celsius (68F to 77F). The ideal humidity is anywhere between 40% to 60% humidity.
This is, of course, an extreme case of lower humidity. If you live in a region where it is very dry, then you should be aware of this condition.
At nighttime, let the tent cool down to the lower 20’s (68 to 75 Fahrenheit), if possible. The cooler temperature mimics what happens in nature and as a bonus, the cooler temperature helps to promote plant growth, just as much as the very hot daytime temps.
