To make things easier for you, we have put together a guide. Keep reading if you are interested in finding out more.

Find the Right Space

Most of the best grow rooms have been designed to make efficient use of space. It won’t matter how big or small your grow room is going to be.

But you will need to make sure that there is enough room to work around the plants. It will also be necessary to have room for housing all of the required equipment.

If you are going to create a commercial grow facility, it might be a good idea to convert an entire room, or an entire section of a warehouse into a grow room.

On the other hand, those who will be designing personal grow spaces might be able to use a closet or small grow tent as their grow space.

Choose Your Flooring Materials

The next thing you will need to focus on when you’re building a grow room is the flooring. Choose a material that will be easy to clean and sanitize. It will also need to be able to resist humidity.

It is not a good idea to use bare concrete. This is because it is too porous. Therefore, it will accumulate moisture and other substances. These substances might leach back into your plants.

Instead, cover your floor with a non-porous material such as paint, epoxy, or some other fluid coating. You also might be interested in laying down vinyl flooring.

Grow Room Tips: Humidity Control

Marijuana plants are very sensitive to heat and humidity. If your growing space has too much humidity, fungi might start to grow on your plants.

But if there is not enough humidity, the plants will take in too much salt. This is because they will soak up too much water at their roots.

If you don’t have the right tools and devices for controlling your grow room’s humidity, your yields will be smaller and the quality of your products will suffer.

Those who do not have very much experience with monitoring the humidity in grow rooms should consider hiring a cannabis operations consultation company to help them.

Choose the Right Light System

It can feel confusing when you are trying to choose the right light system for your grow room building needs. There are many different options to choose from.

Many grow room lighting systems are made up of ballasts, lamps, and reflectors. You can use a ballast to control and regulate the electricity for powering your grow lights.

Lamps generate light, and reflectors will focus this light on your plants. At the very least, you are going to need several main grow lights.

But it is a good idea to also install supplemental grow lighting materials. Supplemental lights will expand the spectrum of light that reaches your plants.

They tend to emit wavelengths that fall outside of the range of UVA and UVB lights. The most common types of supplemental lights are plasma and CDM.

Designing an Air Exchange System

The most simple option for controlling the climate of your grow room is by using an air exchange system. It is important to do this because it is necessary to have ventilation for replacing CO2 that has been depleted.

The more lights that you have in your growing room, the more important it is to create an air ventilation system. You will need to install an extractor fan to take air out of your grow room.

You’ll need an intake fan to bring air into your grow room. These two fans should be located on opposite sides of your grow room.

Keeping Your Grow Room Clean

Don’t forget to add some sort of collection tray to your grow room. This tray will collect dirt, fallen leaves, and water. It will also help you to keep your floor clean.

Grow Room Safety Tips

Contrary to what many people think, grow room light systems tend to be very safe. But it is still important to take the right safety precautions.

Use plastic ties to secure all your wiring. This will keep it out of the way.

You will also need to make sure that none of your electronic devices such as ballasts have the potential to come into contact with water. And don’t forget to check up on your installations from time to time.

Take time to read product instructions, including safety information. Lastly, it is a good idea to have a fire extinguisher close to your grow room in case there is a fire.
