How to Raise Humidity in Grow Tent without Humidifier

Higher humidity is gained when a large amount of water vapor is present in the grow tent. As mentioned before, there are plenty of ways to control humidity in a grow tent.

I will not cover all of them but only the ones that show guaranteed results. They are primarily DIY humidifiers for grow tents that you can make using household stuff.

You can implement any one of them, but doing them together will surely bring a result that will satisfy your humid needs.

Moisturizing the Plants Itself

The first thing you can do to control humidity in grow tent is to moisturize the plants. You can achieve that with a simple spray bottle and some water. Pour water into the bottle and spray it on the plant’s humus and the fronds.

What it will do is evaporate the extra droplets of water that you are giving it. Thus, more evaporation means extra humidity. However, you do need to be present in your grow tent more frequently to water those plants.

On the other hand, overdoing is the opposite of utilizing the advantages of humidity. It will lead to the results that your average humidity wouldn’t even dare to do. The roots cannot absorb any more water at a point, and as a result, crispy leaves and brown limp would be seen.

Soggy Sponges

Wondering how to raise humidity in grow tent for drying? Using sponges dipped into water for a few minutes can be an easy solution for you.

Moistened sponges are considered one of the most effective solutions you can get when it comes to leveling up the humidity. As sponges are capable of absorbing plenty of liquid, making them absorb water will last longer.

If you don’t like to pay a visit to your tent often, this could be a perfect solution for you. All you need to do is take a few sponges and keep them in water for approximately 15 minutes. Later on, take those and keep at least four of them around each plant to get the most effects of low humidity in grow tent.

Controlling Ventilation

You might not have control over the temperature your grow tent is in, but you do have the option to control ventilation. The more ventilation is present in your tent, the lesser your plants feel humid.

Thus, I suggest you guys keep every ventilation corner turned off completely. It doesn’t matter if you are feeling warm in there or maybe getting fried. To fulfill your plant’s needs, higher humidity is a must.

Another key thing to remember to maintain humidity in grow tent is to keep all your fans turned off if available. Fans may help by increasing the airflow and lead to a decrease in pressure that is not suitable.

However, when it comes to both closing the ventilation and turning off the fans then, the science works differently—keeping the ventilation closed and the fans on works collaboratively. As a result, the humidity is spread all over the tent and helps the plants.

Using Buckets

You might be wondering how to raise humidity in grow room without humidifier. Well, it all comes in place with the evaporation that you need, and that’s what buckets containing water can do.

Similar to the soggy sponges, the buckets work in the same way. You fill them with water and place them around the grow tents. There’s nothing more to explain here. The mechanics are the same as every other process. The water gets evaporated and charges up the humidity.

However, another simple hack that you can do is keeping the buckets near the heat source. With the heat source around, the water will be able to evaporate way faster than expected.

Specialized Lights

There’s no way you don’t have lights in your grow tent. However, have you given a second thought to the lights that you installed there? Yes, lights can directly help you for maintaining temp and humidity in grow tent without humidifier whereas it’s the most overlooked one so far.

According to a study, it is seen that LED lights are more effective in tents when it comes to humidity. The LED lights are capable of bringing a magnificent change in temperature around the room and increasing humidity to the next level.

Therefore, installing LED lights will surely help you with the growing process. Additionally, help all the other procedures such as soggy sponge and water-filled buckets to dry up faster.
