13 Best Greenhouse Fogger | Top Fogging Systems

Greenhouse foggers can help you maintain the right environment for your plants by eradicating mold and pests and managing humidity.

Greenhouses are artificial growing areas that aim to provide a suitable environment for diverse plants to thrive according to their needs. They are ideal solutions if you want to cultivate exotic plants away from their natural habitat or increase their yield.

However, a greenhouse needs light, the right temperature, and adequate humidity to enclose the plants in a favorable environment. Besides that, these humid, closed areas are also prone to pests and mold, which must be tackled before damaging your plants.

Luckily, all these aspects can be achieved using a greenhouse fogger. The best fogger for greenhouses uses efficient coverage technology to impart moisture and pesticides into the plants for optimal productivity.

Check out my list to pick the best fogger machine for the greenhouse.

Best Greenhouse Fogger Options

Now that you know how important it is to use a fogger to maintain a favorable environment in your greenhouse, you are probably ready to make a purchase. Unfortunately, however, most people make the mistake of choosing the most expensive, high-tech greenhouse foggers.

Remember, the product with the most extended features and the flashy price tag doesn’t need to work best for your greenhouse. Instead, it is important to assess your needs initially before looking for the right option.

I have included greenhouse foggers from multiple categories, price ranges, and brands in this list so you can easily find one that suits your purpose. So, without further ado, let’s get started.

1. PetraTools Electric Disinfecting Fogger Machine

On the downside, the fogger is quite expensive and designed for commercial use. So, this model might not suit you unless you own a considerably large greenhouse.

However, if your greenhouse is around 30,000 sq ft, you can use this fogger to spray large droplets up to 20-5 microns. Similarly, it is usable for indoor and outdoor plants, so you can use it to disinfect your backyard.

Most importantly, its cordless design ensures hassle-free operation, and it is backed by a 9-month brand warranty if you experience any glitches.

What is a Greenhouse Fogger?

Before getting to the ultimate list, here’s a brief introduction for those new to the concept of a greenhouse fogger system. While treating your greenhouse to manage humidity, mold, or pests, you must impart the chemicals appropriately across the area to achieve the targeted results.

But, just spraying water-based solutions on your plants is not enough. Water has a high surface tension which makes it prone to beading over leaves, leading to inefficient absorption.

That’s why a fogger for the greenhouse is the ultimate replacement for flimsy squirt bottles and sprays. It dilutes the desired product to make it easy for the plants to absorb it through their roots and leaves.

Similarly, some high-pressure fogging system emits their air and create air currents across the greenhouse. This means it uses air as a medium instead of water and suspends the droplets through the air space.

The airflow suspension technique created by a greenhouse fogger is ideally used to manage humidity and mold accumulation. On the other hand, the suspension of minute droplets through misting and hydraulic spraying targets insect and pest eradication.

How Does a Fogger Help a Greenhouse?

In my list below, you will find various options that can make it confusing to choose the best fogger for a greenhouse that fits your needs. However, to make the right choice, it is essential to know the multiple ways a fogger helps keep your greenhouse healthy and thriving.

This way, you can determine which aspect of your greenhouse needs to be treated and choose a greenhouse fogger accordingly.

Apart from the countless technological aspects of different greenhouse foggers, you will find most with differing purposes and some multi-purpose products. For example, there’s a dedicated fogger for humidity or a greenhouse portable fogger to use at more than one location.

In a nutshell, a greenhouse fogger helps a greenhouse by maintaining the ideal environment for the plants inside. For instance, if the humidity levels are low, the plants will not conduct photosynthesis effectively, leading to a low yield.

A greenhouse fogger for humidity can solve this problem quickly by providing extra moisture for healthier growth. On the other hand, you can use greenhouse fogger insecticide to eradicate pests and insects from your greenhouse. Greenhouses are enclosed areas full of moisture and plants, making for a bountiful environment for problems.

Greenhouse foggers help impart insecticides through misting and generating artificial airflow to get rid of creepy crawlies for good!

  • The size of your greenhouse.
  • The climate you are trying to create.

How to Set Up and Use Your Greenhouse Fogger

Once you have decided on the best greenhouse fogger for your needs, it is important to set it up correctly and use it properly. Please consult the user manual with your particular model for specific instructions. In general, however, the process is as follows:

  • Hang the fogger from the ceiling of your greenhouse using the provided hooks or hangers.
  • Determine the number of nozzles needed. Calculate the water and air flow requirements and a compressor with the required pressure.
  • Connect the fogger to a water source using the provided tubing.
  • Plug the fogger into an electrical outlet.
  • Adjust the settings on the fogger to create the desired climate.

Benefits of Using a Greenhouse Fogger

The benefits of using a greenhouse fogger include:

  • Increasing humidity levels in the greenhouse can be beneficial for plants.
  • Cooling down the air temperature in the greenhouse.
  • Creating a more comfortable environment for people and plants.
  • Helping to prevent diseases and pests. 
  • Provide a uniform wetting.
  • During the summer, humidifies the air and reduces temperatures.


Are foggers good for plants?

A plant fogger is a device that emits a fine mist of water and nutrients to help plants thrive. It can be an effective way to provide moisture and nutrients to plants without overwatering. However, it is important to use the right type of fogger and to follow proper guidelines to avoid damaging the plants. Additionally, some plants may not benefit from fogging and may require other methods of care.

What is the difference between fogging and misting?

Fogging produces droplets that are smaller than 50 microns, while misting produces droplets that are larger than 50 microns. Fogging is typically used for disinfection purposes, as the small droplets can penetrate hard-to-reach areas and kill bacteria and viruses. Misting, on the other hand, is used for cooling or humidifying purposes, as the larger droplets can provide a refreshing mist without wetting surfaces.

What is plant fogging?

Plant fogging is a technique used to increase humidity levels for plants by dispersing a fine mist of water into the air. This method is particularly useful for plants that require high levels of humidity, such as tropical plants or those grown in arid environments. Plant fogging can also help to reduce the risk of pests and diseases by maintaining a healthy and humid environment for the plants.

Can you use a fogger for fertilizer?

A fogger can be used for fertilizer as a way to distribute liquid fertilizers evenly over a large area. This method is especially useful for outdoor applications, such as lawn care or crop farming. However, it is important to note that not all types of fertilizers are suitable for use with a fogger, and the appropriate safety precautions should be taken when handling and applying liquid fertilizers.
