Grow Room vs. Grow Tent Difference
Grow rooms or tents are uniquely designed to be suitable for indoor gardening.
If you’re into gardening, chances are that you’ve come across the terms “grow room” and “grow tent.”
But, how do these places differ, and do they require different humidity levels?
The answer to the first question is a bit more straightforward.
As noted, grow rooms are rooms that are specifically designed for plants growing indoors.
These rooms are made into your home, and they don’t require the use of special outside equipment to make them viable for plant growth.
Grow tents, however, are a bit different. Instead of being made into the fabric of your home, these tents are portable.
Though they are also used to make an indoor growing space for your plants, they aren’t set in stone.
These pre-made tents are designed to be added to a room to turn it into a grow room.
Once they have been used, they can be moved to another room or area if need be.
Humidity for Plants: Why It’s Important?
Your grow room will likely be the most humid in your house.
And for a good reason, you want to ensure that your plants have enough moisture.
Without it, they can dry out and die. Don’t overdo it, though.
Too much moisture can also cause your plant to suffer, so be sure that you’re providing the right misting levels to them along with proper moisture.
Believe me, by doing so, you can make your at-home grow room a success.
Why do You Need a Humidifier for Grow Room?
If you’re looking for your plants to survive, you will need to invest in a humidifier.
A proper humidifier can provide the humidity needed for your plants to thrive.
Because here’s the deal: plants typically suffer or even die when they’re placed in dry environments.
This means that you’re not going to want to let your grow room get too dry.
With this in mind, however, do note that different plants require different humidity levels (between 45% to 60%).
A cactus, for instance, won’t require as much humidity as a plant from the rainforest.
Make sure that you understand your plants’ specific needs so that you can set your humidifier to the correct levels.

Can Misting The Plants Increase Humidity?
How to mist plants and their leaves in the right way is an art you should learn to keep your plants happier and healthier.
Your indoor plants in a greenhouse or in a garden need to be misted – just like nature waters them from top and bottom.
Most of us water the plants from the bottom by watering the soil daily. Plants get hydrated from the bottom by extracting the needed moisture from the soil.
But to hydrate them from the top, it is essential to manually mist them occasionally.
Wetting the leaves using a spray bottle equipped with a fine misting nozzle is a great way to do so.
Depending on the plant type and its requirement, you should mist them regularly by holding the nozzle a few inches away from it.
Mist the leaves and plants from all possible angles. Make sure that the misted leaves seem to be wet but not dripping.
A good room humidifier is also a great way to automatically hydrate your plants from top to bottom without worrying about over-hydration.
What Should Be The Ideal Humidity for Plants?
The best temperature and humidity levels for indoor plants may vary significantly depending on the plant species.
In general, for most plants, optimum humidity levels are between 50 to 60%.
During winters or sweltering summer days, when the air outside is dry, you need to get the best humidifier for your plants.
However, before maintaining these levels by using a plant humidifier, it is good to research your plants’ species and the humidity levels that are specifically recommended for them.
For instance, if you are growing or cultivating a specific variety of edible mushrooms, you should maintain a specific temperature and humidity inside.
If your mushrooms are left in a place with high humidity (or even worse, stagnant water), they may likely get mold infestation which can even make them poisonous.
How to Make a DIY Humidifier for Plants Naturally?
As such, there are many ways to increase humidity naturally without using an air humidifier.
But when it comes to making a DIY humidifier for your houseplants or a grow tent, you should try to be specific.
Few exciting ways to make a DIY greenhouse humidifier are:
- Use humidifying plants
- Increase water sources
- Use pebble trays for plants
- Lower the surrounding temperature
- Use a humidity tray or mats for plants
- Use the fan correctly and ventilate the grow tent
What Happens When There is Less or High Humidity In A Grow Room?
Ultimately, we have reached the point where you may have understood the importance of plant humidifiers for your grow tent or grow room.
If you do not care about buying one, it may lead to very low or very high humidity – both of these conditions are not good for your houseplants.
Low humidity levels inside the grow room may cause dry, curled brown leaves, stunted or wilted plants, and increased pest infestation.
On the other hand, high humidity levels may cause root diseases, grey molds on leaves, and nutrient deficiencies in plants.
