Buyers Guide

When it comes to buying a ventilation kit for grow tents, there are a few things a consumer needs to know. In fact, these tips will save a grower a lot of time and frustration.

What’s in the Kit? – When considering a certain ventilation kit, it is imperative that you know what comes with the package.

For instance, the kit should include the basics which are the fan, the carbon filter, and the ducts. Every now and then, a kit will contain extras like a timer, fan speed controller, or hygrometer.

What’s the CFM? – The CFM is the specifications of your fan. It stands for Cubic Feet per Minute which is the measurement of air flow speed.

The bigger the CFM, the faster the air flows out of the fan. For larger tents you need a bigger CFM.

Is the Fan Noisy? – One of the biggest complaints about ventilation systems is the noise of the fan. Many growers state that the fan eventually becomes rather loud and obnoxious.

Make sure to check reviews about fan noise before buying a kit, especially if you are sensitive to loud sounds.

How absorbent is the carbon filter?– The carbon filter is a very important feature. It ensures growers that the odor of marijuana does not leave the tent.

For the most part, weed is very strong smelling and can easily permeate the neighborhood. Therefore, it is essential that you make sure a ventilation kit comes with a high quality carbon filter.

Some of the best carbon filters are composed of Australian charcoal.

Importance of Ventilation

One of the biggest mistakes growers make is assuming that ventilation is not very significant. Quite the contrary, ventilation is just as important as light, nutrients, and heat.

In fact, when a grow tent is well ventilated, it ensures that your plants are in optimum environment for health and growth. Good ventilation also offers other benefits:

  • Heat has a hard time accumulating. With excess heat, plants do not do well and can quickly wither away and die.
  • Proper ventilation minimizes pests and insects. In fact, good ventilation improves circulation and easily filters out the bugs.
  • Utilizing a clip-fan helps improve air circulation. In addition, it supports a light breeze within the tent which is beneficial for branch and stem growth.

The Size Extractor Fan You Need for a Grow Tent

The size of your extractor fan in relation to the size of your grow tent is also important. Determining the size of your extractor fan is pretty simple. The formula is actually pretty basic-

Multiply the room volume (cubic feet), carbon filter factor (+25%), insulation factor (±20%), the light factor (+10% for 1000W), and ducting (+10% for 10 feet). This will give you the fan size in CFM .

A more mathematical formula when using a carbon filter is:

[(grow space width X length X height) / 5] X 1.2 = recommended CFM

Grow Tent Ventilation Setup

Your ventilation system can be set up in various ways. Here are a few options:

Your ventilation can be set up in a number of ways. Here are some possible configurations:

Placing the right fan – when fans are functioning properly, you have control of the air flow. Basically, there are two types of fans:

  • Air Extractor fan systems – takes out old and stale air and brings in fresh air. This is one of the most effective systems for premium air flow.
  • Oscillating fans – cost effective and efficient. A constant influx of air is blown around the plants. Includes an easy set up. This system requires that you have more than one oscillating fan.

Passive Intake-

Passive intake is reliant on passive airflow and negative pressure. It blows air out without a fan blowing inside. Basically, there is a hole that allows the air to enter the tent passively.

Active Intake-

This system draws air from the fan directly. The air from one fan blows air in and another blows the stale air out.

Controlling Humidity-

Another important factor in ventilation set up is the ability to control the humidity to prevent plant diseases. Basically, you want to lower the humidity levels by pushing the humid air out by utilizing an exhaust fan.

However, there are rare times that you may need to increase the humidity. This is accomplished by sealing off the grow tent and turning the exhaust fan off.

Keep in mind; correct humidity levels are very important. For healthy and thriving plants, it is imperative that your research the amount of humidity that is needed for your plants.

Injecting Carbon Dioxide-

For transpiration to take place you need to inject CO2. Transpiration is the process of water moving through a plant and its evaporation from aerial parts like stems, leaves, and flowers.

For the most part, an enclosed area like a grow tent typically has low levels CO2. Therefore, CO2 injection is needed for a healthy plant.

Common Questions

When designing and installing a ventilation system, there can be many questions and concerns. Here are answers to some of the most common questions about ventilation systems for growing marijuana legally:

What are the different kinds of ventilation setups?

Generally, ventilation setups are categorized by how the filter and fan are positioned. For the most part, there are four different kinds of ventilation setups for grow tents:

  • Fan in, filter in
  • Fan out, filter out
  • Fan in, filter out
  • Filter in, fan out

The majority of growers prefer to use the ‘fan in, filter in’ method. It offers better air flow and removes odor more efficiently. Then again, all setups vary, each with the pros and cons.

Why does marijuana smell and how to get rid of this smell?

Marijuana odor comes from the terpenes produced by the plant. Terpenes are also what make the buds sticky. These chemical compounds are important for repelling pests and insects.

A charcoal filter is needed to get rid of the terpene odor.

What is a clip-on fan and what are the benefits of using one?

A clip0on fan is a tiny rotating pedestal fan that is typically clipped on the top bar of the grow tent. It helps ensure proper ventilation within the tent.

In fact, since heat rises, it drastically helps remove and circulation warmer air.

Conclusion

When it comes to buying the ideal ventilation kit for your grow tent, it is easy once you apply the various tips in this article. Sometimes it is best to start small and upgrade as you learn, especially if you are a beginner.

However, even experts have excellent production with the right ventilation kit for their grow tent.
