Tip #1: Manage Humidity

What are the humidity levels in your grow tent?

This is a question you have to ask and answer. The plant will start to release water vapor causing a biological upsurge in humidity. If left uncontrolled, the damage can be far-reaching and catastrophic for your yield. Countless indoor gardeners talk about this being a crucial mistake they made while learning.

Why does humidity matter?

Humidity damages the growing environment for plants. It eliminates the strength of your growing setup and leaves it in tatters. Your grow tent will work poorly if you leave the humidity levels untouched.

Studies have shown an increase in humidity correlates with an upsurge in pest infestations.

Take the time to set up a resolute ventilation system with the help of a top inline fan. This is how you will be able to gain control of this biological phenomenon. If the ventilation system works well, it will end up augmenting your yield and pushing it to new heights.


Tip #2: Eliminate Excess Heat

Another point of focus should be the heat levels in your grow tent. What is the temperature right now? Is it rising? If so, you need to make appropriate and immediate adjustments to help your yield. Those who ignore this aspect of their ventilation setup will see mediocre results.

How do you eliminate excess heat if it’s becoming a nuisance?

Understand the source of your problem. While modern day grow lights are exceptional, they do emit heat. Since indoor gardening conditions hinge on minute details such as temperature, you need to pay attention to changes. If the temperature rises slightly, your yield will be impacted.

Even a slight increase can make a noticeable difference in how your plants grow.

The best option is to look for a quality grow light to reduce the amount of heat being emitted. Plus, pay attention to the distance between your tallest plant and the light itself.

It’s recommended to have at least 18-24 inches between them at all times.


Tip #3: Manage CO2 Levels

Just like heat in your grow tent, it’s important to look at the CO2 levels. If the CO2 levels start to rise or become overpowering, you will notice a change in your yield over time.

Remember, plants require CO2.

If you are not delivering enough CO2 to these plants, they will wither and lose out on vital nutrients.

Indoor gardening can start to pose this problem because your grow tent is sealed shut. If you are not ventilating it, you are never going to manage the CO2 levels as necessary.

The CO2 levels will deplete, and you will pay the price.

This is why you want to have a proper ventilation setup (i.e. inline fan) in pace so external air refreshes the grow tent. If not, you are going to see inefficient growth over time.


Tip #4: Eliminate Pests

Pests are a major nuisance, and poor ventilation can exacerbate the situation.

The goal should be to prevent pest infestations and eliminate them. However, you need to recognize it is your ventilation setup in the grow tent that will carry value. If you get this spot on, you will never have to deal with pests.

Pests tend to come when the conditions are humid, moldy, and stagnant.

If you eliminate these conditions, you will eliminate the pests. It’s as simple as this.

The pests will be unable to lay their eggs without the right environment around them. If you cut the source of their biological growth, they will leave and die out. Set up a good inline fan for your grow tent and notice an immediate change.


Tip #5: Emphasize “Wind”

This might be one of the most important grow tent ventilation tips. You need to emphasize wind inside your grow tent and recreate it with purpose.

Why is this necessary?

Your plants are naturally reliant on wind pressure or wind stress. If the plants are not pushed by wind, they will never gain the strength to grow. You need to have a proper fan that can push them without causing breakage.

It is an essential requirement and one you have to take seriously. If not, you will create weaker plants that won’t grow to their full potential.


Tip #6: Find The Right Inline Fan Based On CFM Metric

The CFM metric (Cubic Feet/Minute) is a formidable tool to use while picking out a good inline fan for your grow tent.

Go through all of the inline fans and measure for efficiency.

How are you going to measure the CFM? Volume of Grow Tent (LxWxH) x Efficiency Drop (Volume x .25).

Use this formula, and you’ll find out the exact CFM.


Tip #7: Improve Performance of Ducting

In general, the run-of-the-mill grow room will incorporate aluminum ducting and its performance hinges on you. If the ducting isn’t optimized to perform, it will start to fray at the seams.

So, what do you consider while improving it?

You want to smooth out all wrinkles in the ducting and consider rerouting it. The goal is to have fewer turns from point A to point B. Also, it’s nice to contemplate shortening the length of your ducting.

By doing this, you are going to increase air flow for your grow room or grow tent. Remember, it is simple changes that can bring the biggest results as you look to optimize.
