What’s the ideal indoor humidity for Cannabis in your Grow Tent?

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.

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. 

What Should My Grow Tent Humidity be for Marijuana?

As stated earlier, the grow tents humidity should be somewhere in the range of 40% to 60%.

There are a couple of things to take note of, if you want to increase your chance of success.

• It is preferred your pot plants are grown in higher humidity while in the veg stage and lower humidity in the budding stage.
• For the flowering or budding growing stage, it is important to decrease the humidity more and more as you get closer to harvesting. This mimics what happens outside in the fall season.

What Happens if Humidity is too Low in Grow Room?

It is possible to not have enough humidity in your grow tent/room during the vegetative stage. The cons to this happening include your plants growth being stunted. The stomata on your plants could potentially close-up which means they aren’t getting the oxygen exchange they need to be getting. Your plants might not die, but their growth will indeed be affected.

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.

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.

How Do You Keep Humidity High in a Grow Tent?

Keep humidity in a marijuana grow tent involves two aspects. Providing a source of humidity and keeping the humidity in the tent for as long as possible. Let’s look at both.

Creating humidity in a grow tent shouldn’t be that hard, one would think. I have a cool mist humidifier with a humidity setting so it shuts off when the desired level of humidity is reached.

Keeping a tent humid is all about sealing up any areas of the tent that will allow air out of or into the tent. Using tuck tape or tape of your choice, if you taped over all of the stitching on the inside of the tent, it would help in stopping the tent from losing humidity so quickly.

Choosing the Best Humidifier for Grow Tent

If you want to find the best humidifier for grow room that perfectly meets your gardening needs, you should know what features to consider in your situation. Here are some of them:

• Type of humidifier. There are three main categories of this device: evaporative, ultrasonic, and impeller. The evaporative humidifier has a fan that blows the moisturized air through the special wick. They are effective but can be noisy. Ultrasonic devices distribute the moisture by the vibrating nebulizer. They are noticeably quieter. Impeller models produce mist by the disk rotation.
• Tank capacity. This parameter defines how long the humidifier can work without your interference. Devices with smaller tanks require frequent refills, which can be inconvenient sometimes.
• Treated area. Consider the size of your grows room before choosing the humidifier. For large areas with high ceilings, you will need powerful models with large tanks or direct connection to the water supply.
• Noise level. If a grow room is far from the living and sleeping areas, then you can skip this aspect. But in other cases, you should pick the models with a noise reduction feature.
• Safety features. Humidifiers are electronic devices, so safety measures are significant here. Auto shut-off can prevent working without water or when there is enough moisture in the air. Overheating control should also be included.
• Working hours. This parameter depends on the tank capacity, energy source, and overheating control. Define how often you can check and maintain a humidifier in your tent, and use this information to select the model.

Right Position for Pot Humidifier in a Grow Room

It is important to place the hydroponics humidifier properly to ensure efficient moisturizing and lush growth. Surely, there are different rooms and plant coverage in them. But here are some options for the humidifier placement:

• Hanging on the wall. This option saves space and provides even mist distribution. But you should install the device properly, and you might require professional assistance or special details.
• Freestanding. If you have enough room on the floor, you can pick the freestanding models. They do not need an installation and also can be wireless. But they might not be powerful enough to deliver the moisture to the upper levels. As an option, you can place the freestanding device on a table or a chair.
• Ducted. This is a rare but still available option, which allows saving space in a small room. The device is placed outside the room, but it is ducted to the growing area.

Keep in mind, while choosing a humidifier model or its position, make sure the mist will be distributed evenly. This is important for large rooms, as small areas are easier to treat. Also, the airflow should be strong enough to ventilate the room and prevent the mold and spots on plants. For ducted and hanging devices, the remote control will be handy.

Conclusion

You want your grow room humid, but not wet because standing water should never be in your grow. Therefore, choose a good quality humidifier that will disperse a fine misty spray. But, there are other humidifier features you have to consider.

We found out that it is extremely important to match the size of the humidifier to the size of your room.

There is no doubt that a bigger humidifier may instill excess humidity in your grow room, causing condensation as well as bacterial growth. Overall, choose a unit that is easy to operate and maintain.
