How To Set Up Your Indoor Grow Room-Part IV

In this article, we’re going to share the remaining step 6, 7 and 8 of setting up indoor grow room with you. It includes how to set up a ventilation system, keys about temperature control and our last step:  start plantation. Let’s get started!

Step 6: Set Up a Ventilation System

Before we dive into how to set up a ventilation system, we must understand why it is necessary and how it creates an impact inside your indoor grow room.

Need for CO2:

We know plants need two things to create glucose; one is water and the other carbon dioxide.We provide water to plants, but the carbon dioxide is taken from the air. These two things are essential for photosynthesis. Plants take carbon dioxide and emit oxygen as a byproduct, so if there is no fresh air inside the grow room, carbon dioxide will deplete from the air. The shortage of carbon dioxide is not good for plants, and they won’t be able to produce their food. Therefore, it is essential to replace the air with fresh air.

Humidity Control:

Another important issue is the humidity level. The humidity of an indoor grow room increases with time due to transpiration and water that we give to plants. High humidity is an issue, and it must be controlled through ventilation. It provides a favorable environment where molds and bugs exist. It will badly affect your plants, so it is vital to remove the air to reduce humidity.


Ventilation also reduces the temperature of the area. The heat from grow lights accumulates in the area, and it is harmful to the plants. So, the heat must be expelled out of the indoor grow room.


Beginners might not have an idea of the smell produced by the plants. If you want to keep the area smell-free, then air ventilation is a must. The smell that accumulates in the air is quite irritative for your family and people visiting the home. Make sure the ventilation is enough to reduce the smell produced by plants.

Step 7: Temperature Control

Temperature control is quite important for the optimal growth of plants. It also depends on the plants, and you need to maintain a suitable temperature that can give you better results. For temperature monitoring, you need to install sensors and devices that will monitor the temperature of your grow room all day. It will help you keep an eye on the changes and what you need to do in order to control the temperature. Thermo-Hygrometer can record temperature as well as humidity. It is the best option for indoor growers.

Extreme low and high temperatures are not suitable for plants. If the temperature is too high, you will need more water, and the plants might suffer from water shortages. On the other hand, low temperature creates a hindrance in the absorption of nutrients. Moreover, the moisture also remains on plants, which can lead to mold. For the control of temperature, the optimum solution is an air conditioning system. You can control the temperature according to the climate where you have the grow room. Ventilation systems also assist in controlling temperature a bit; however, we cannot rely only on it.

Step 8: Start Plantation

Your indoor grow room is ready, and now, you can start the plantation. As you have set up everything, now it is time to place the pots/seed starter plugs/fabric container. You can sow the seeds and start watering them from time to time. Make sure to control the temperature, humidity, light, ventilation, and other factors.
