How To Set Up a Grow Room Step By Step?

Essential Kits and Accessories For Indoor Gardening Systems:

The hydroponic gardening tent comes with many advantages to give the plants the ideal environment. When it comes to the indoor grow room, we will borrow a leaf from the best grow tent kits and use that as a reference point.

There are some elements that you will need for this process.  You may not use all of them, but it would be advisable to have all the listed items to not get stranded during the process. Here is the full list:


All you need is to find the desired space and then start building your indoor grow room. With this guide, you should provide an excellent area for your garden and enjoy high yields. Follow the steps below:

Step 1: Soil or Hydroponics?

Soil or HydroponicsEven if you are using the grow tent, you will need to have a clear gardening plan. This is what I put as my first step, whereby you will need to be sure of the method of cultivation. There is an option of using hydroponics, and the other option would be the use of soil.

This is essential in your preparation for the indoor growing room. If you choose to use the soil, then your garden will likely be an outside one. The grow tents have an advantage as that they allow you to grow plants in gallons and pots.

Step 2: Space to Set Up

We don’t want to build your indoor garden and then move it to a different place. You may also be shocked to realize that the framework does not fit through your doorway.

It is vital to have the number of plants in mind when setting apart space for your garden. Generally, I advise growers to work with one plant per square meter, for bigger plants, or 25 smaller plants.

The issue of having control over the environment should not be ignored, and you will need to have access to your grow tent without a problem. You need to have adequate space for all the accessories and also have room for maintenance and cleaning.

Step 3: Mounting the Frame


Mounting the FrameHaving finished the preparations, let’s dive right into the actual process of building your indoor plants growing room. You will need to start by putting together a frame that will be used as an indoor garden.

When doing, you should choose the shape that appeals to you and ensures that you are making sturdy joints.

You will also need to have some support bars, which you will use to hand the various accessories that are usually found in a high-quality tent. You should be keen on the type of materials you are applying for your grow room frame.

Step 4: Cover the Frame

The essence of a hydroponic grow tent is that plants will get the perfect environment, which should be your goal, even with the indoor gardening room. As such, you should cover the frame with the ideal fabric.

It is essential to ensure that you have a tear-proof fabric that will protect your plants from external interference.

Step 5: Ventilation Set Up

You don’t want to have to deal with mold and mildews in the grow room, which is the primary purpose of having proper ventilation.

Fans are an integral part of the air control as they will help in air circulation, which will help the plants grow healthily.

With proper setup, you will be able to keep the temperature and humidity at the desired levels. A simple way of ensuring that your indoor garden is ventilated is cutting a hole on top of the closet. You may also notice that the quality tents come with filter strips and observation windows.

If you cannot cut through the material you have used, you should find a way of leaving the door slightly open to be proper airflow. Ducting and carbon filters can also be included as part of the ventilation.

Step 6: Enhancing Indoor Grow Room Walls

Enhancing Indoor Grow Room WallsThe walls of the indoor gardening room are essential and need to be prepared for the process. This will be done by ensuring that the walls are reflective.

This is why the indoor plants growing systems come with a Mylar lining inside the canvas to make it reflective.

For the grow room walls, you can choose to use mirrors or the bubble insulation with reflecting capabilities. This is one of the ways that will help your plants to grow in the right manner.

The light emitted by theinstalled grow lights will be intensified by the reflective walls.

As such, every part of your plants will have sufficient light.

Step 7: Install Grow Lights


Having proper lighting is imperative for all indoor gardening activities, even when you have the right size and high-quality tent. When it comes to growing lights, there are a couple of options to choose from, including:

Install Grow LightsYou can select the type of lights that you believe will be more effective. I have noticed that most HPS and LED grow lights come with built-in fans that will be useful in air circulation and regulation of the heat.

Fluorescent and HPS lights are known to become quite hot, and they may require additional fans to prevent any burning of the plants. You should use rope ratchets to hang your lights, as this will allow you to adjust them accordingly as the plants grow.

Step 8: Climate Control Setup

Climate Control SetupAs we had highlighted earlier, the beauty of the hydroponic grow tent is that it will give you full control of the environment.

Some of the critical factors that you should consider controlling include temperature, C02, and humidity. These are climatic conditions that will vary from place to place, depending on the region that you are in. An ideal number of fans depends on the environment that you wish to create.

There are accessories designed to help you set up a conducive atmosphere for the plants. You can choose to have a humidifier, which needs to be cleaned quite often.  You should have the humidifier’s water changed daily – this is critical.

If you allow the water to stay there, it will be a breeding place for pathogenic microbes, which are detrimental to your plants.

Step 9: Collection Rack or Screens?

Collection Rack or ScreensIf you chose to grow plants using the soil, then you need to have a collection rack. You can use wire shelves to make the collection rack in your indoor grow room.

This should be placed at the bottom so that the plants will rest on the rack. This will save the plants from touching the ground, and they will have proper airflow.

Remember that the rack makes it much easier to clean the room. You will be able to remove all the debris and other unwanted items without touching the plants.

You may also opt to use the screens, and in this case, you need to find one that will fit inside the room. For younger plants, the screens may be ideal as they will help the plants go through the vegetative cycle without any problems.

You can have the screen attached to the collection rack or the walls of the indoor grow systems.

Step 10: Start Gardening


Having followed all the steps carefully, you are now ready to start farming. You can plan to place the plant’s inside the grow room. However, you should run a safety check to ensure that all the installed accessories are working as expected.

It is paramount to test the environment to be sure that it is ideal for your crops.

Space out your plants in such a manner that they will not be forced to compete for some essential nutrients. If you are using pots, you should have them 3 inches apart inside the grow tent.

Final Thoughts:

There you have it! You can easily watch the plants as they thrive inside the grow room you have prepared.

You need to ensure that you are not interfering with the environment, which may affect the plants. Reduce the number of times that you will go into the room not to contaminate the plants.

With the indoor grow room system, you can grow any plants you desire without considering the season.

Assembling a grow tent from scratch is not an easy task, but following our guide, you should find it a bit easier. You do not need to have a lot of space to work with the area you have.
