Best 6 Grow Room Ozone Generators FAQs

Is it beneficial to use ozone generators to prevent mold growth?

Yes, using ozone generators to prevent mold growth is proven to work. However, if your grow room is already attacked by mold, you have to clean and pristine your grow room before starting growth in it again.

Is it true that ozone generators can remove strong odors?

Yes, ozone generators are capable of removing any strong odors coming out of your grow room.

Do I have to check the ozone production levels of an ozone generator and set its running time?

You, without a doubt, have to look for the amount of ozone produced and the ozone generator’s runtime. It is very important to take care of these factors for yourself and your plans for life.

Can I use the exhaust while the ozone generator is running?

If you use exhaust and ozone generators simultaneously, the ozone being produced will leave the room. It is not advised to keep the exhaust turned on while the ozone generator is running.

Can I enter my grow room while the ozone generator is working?

When the ozone generator is running in your grow room, stay out of your grow room.

Is it true that ozone molecules are dangerous for health?

Humans and animals cannot break down the ozone molecules that enter the bloodstream. A small amount of ozone gas can hurt you. Upon inhaling ozone, one starts coughing and eventually dies. While using the ozone generator, do not go inside the grow room.

Is the usage of ozone generators for longer periods beneficial for plants?

It is useless to expose plants to larger quantities of ozone gas. Ozone molecules stop plants from producing chlorophyll, an important component of plants responsible for producing energy for them.

Using an ozone generator for longer periods kills the healthy cells of the plants.

Is it inevitable to use ozone generators?

No, using an ozone generator is entirely your decision. If you can use healthy practices to stop odor spread, avoid mold production, and kill pathogens, there is no need to buy an ozone generator. However, using ozone generators can save you time.

Are there any safety measures to follow while using ozone generators?

Ozone generators require you to follow safety measures while using them. Keep all LED lights off when an ozone generator is running, have a proper setup of ventilation, and choose the size of the ozone generator while keeping the size of your grow room into consideration.


In the case of grow rooms, you cannot use perfumes to kill any bad odor coming out of them. Using any chemicals to prevent mold spread and kill pathogens and pests is costly. However, a single device, an ozone generator, can achieve all of these goals.

The best thing about ozone generators is that they do not require any maintenance at all. Buying an ozone generator means you have achieved a long-lasting solution to the odor problem.

However, before buying an ozone generator, you have to make sure that you buy the best one. Not all ozone generators are capable of achieving your goals. If you put an industry-scale ozone generator in your grow room, it might not be suitable for both you and your plants.

Before picking an ozone generator, make sure that you follow the guidelines given in this article. Carbon filters work through filtering, but ozone generators work by destroying odors or odor control. Plugin ozone generators are great for smaller tent setups and the likes of the Uvon Air are for bigger setups.  Using ozone generators requires you to follow strict safety measures. Keep the safety standards up to the mark so that you and your plants stay healthy!
