How to Build a Grow Room In Your Home

If you love to grow plants, you have probably encountered some kinds of plants that grow better indoors than outdoors. If you like to grow plants indoors, one option for you is to build a grow room.

A grow room is basically creating a smaller version of your outdoor garden, except that it’s within the boundary of your home. This allows you to control the various factors that would induce the growth of plants.

Here are some factors you need to consider before you start to build an ideal grow room:

Privacy And Security Concerns

For some growers, privacy and security are very important when they start building a grow room. This might be the case when they choose to grow Cannabis Sativa plants – specifically hemp marijuana plants – in the grow room.

Now before you go getting your knickers in a knot – The hemp plant produces a broad range of cannabinoids, including tetrahydrocannabinol (THC), the intoxicating cannabinoid in marijuana. However, hemp does not produce enough THC to create intoxicating effects when consumed. 

Aside from initially checking whether the laws of your locality or home country permit growing such plants, you should also check if the house or building where you’ll be setting up your grow room is in a community with a high crime rate. If it is, then it becomes necessary to either make the entrances and exits of the house or building more secure or to move your grow room to another location where the crime rate is lower.

Essentially, you’ll have to consider the privacy and security concerns to see if it’s ideal for you to build a grow room.

Length, Width, And Height Of The Grow Room

When building a grow room, it’s necessary to have an approximate idea of how big your ideal grow room should be.

This is because some people have outlandish ideas regarding how many plants they want to nurture in the grow room, but then encounter the reality that they only have a small room for their plant growth project. So, create an initial sketch on paper detailing the length, width, and height of your ideal grow room that’s drawn to scale, and assign parts of the grow room to particular plants. Then, look for a space within your home where you could set up your plant growth equipment.

Take the measurements of the actual room to see if it matches your plan. If not, you will need to adjust the sketch.


There are two concerns when it comes to ventilation. First, will you be able to breathe in the grow room that you’ll be constructing? Second, will your plants have enough carbon dioxide to breathe in so they can release oxygen?

These two concerns are very important when your plants are still seeds – if you can’t breathe and if your plants haven’t grown yet, then no one can work in that grow room. As a solution, set up a ventilation system that you feel comfortable with while working on your plant growth project. The ventilation should allow carbon dioxide from outside to come in as well. Doing so will provide your plants what they need to breathe in.

Room Temperature

You should avoid making an above-ground room into a grow room because windows will permit sunlight to come in, affecting the room temperature.

As a plant grower, you’re probably thinking of how to keep your plants comfortable enough to grow without hindrance. A cool basement will be useful, especially if you’re a beginner in building grow rooms or in raising indoor plants.

Access To Electricity And Water

Another reason some growers prefer basements as grow rooms is that their plant growth project will require them to have steady access to electricity and water. Think of your grow room as a kind of mini-garden where you’ll be handling soil and water for the benefit of your plants.

You need the electricity to power grow lights, for one thing, and for any other equipment required. You’ll also need to water your plants regularly. Since basements are usually fitted with light and water sources, it’s a no-brainer that you should choose a basement for your grow room.


People have various reasons for choosing to create a grow room in their house, but they all boil down to one thing – they want to raise indoor plants. If you’re opting to put up a grow room yourself, it’s important to consider two parties in the equation. Firstly, you want to remain comfortable while working in the grow room. Secondly, the other party is your plants so bear in mind their comfort as well.

Even beginners have a good shot at making a great number of plants sprout, grow, and flourish if they have a great grow room to conduct their plant projects in.
