Indoor fans are a necessity to have a prosperous garden success. In the following, you will learn which are the best grow room fan and what type you need.
How to Ventilate a Grow Room
Knowing how to ventilate a grow room correctly is the first step towards the incredible journey of reaping a great harvest. Ventilating a grow room is a hard task for some people. That is not just for beginners, but also to seasoned indoor growers. Take a look at the steps of ventilating a grow room:
Install fans
You will first need to install the fans. The market provides two types of fans; oscillating and air excavator system. One good thing about both of these is that they are affordable and come in various models. You will always find a fan that best suits your grow room at the cost that is most affordable to you. However, it is good to remember that high quality is always better.
An oscillating fan is designed to blow air all around the plants. That helps to circulate air inside the grow room as well as keep the place fresh. Most fans in the market are lightweight. That enables the grower to move them around the grow room to a suitable spot with ease.
You should, however, ensure that the fans are not pointed directly toward the plants as this can cause windburns to the plants.
The air excavator, on the other hand, helps blow old air out of the grow room. That is important as it allows fresh air to flow in, which is needed by the plants. You should note that buying an excavator that can remove all the old air from the grow room within the shortest time possible is the best practice.
Understand the humidity condition of the room
For your plants to grow correctly, they will need a certain level of humidity. While it can be hard to know the exact level of moisture in the room, many tools on the market can help. Most farmers install a humidity gauge to help monitor the humidity condition of their grow rooms.
It is essential to understand the humidity level that your plants need to thrive properly. Many institutions can help you know the humidity preference of your crops. [1]
Determine CO2 level
While most plants require carbon dioxide to manufacture food correctly, each requirement level differs. It is for this reason that crops experts recommend research to determine the level of CO2 that best suits your plants.
After determining the level of CO2 your plants require, you can then inject it into the grow room. However, before inserting, you need to ensure that the chamber is sealed correctly so that the CO2 does not escape.
As you pump CO2 into your grow room, it is also important to have lights in the room. LED grow lights help the plants to utilize the CO2 that you have injected into the chamber. (Learn more about CO2 bags here)
What Kind of Fan Do I Need?
Even after knowing that you need to install a fan, one question that you must have a proper answer to is “What kind of fan do I need?” The answer to this question will depend on several factors. As already mentioned above, there are two types of fans that you can buy for your grow room.
The size of the indoor place will help you determine the kind of fan to purchase. Your budget is also an essential factor to consider. In a nutshell, therefore, whether you choose an oscillating fan or an air excavator system, you need to pay attention to its model, affordability and the size of your grow room.
