How To Choose The Best Greenhouse Ventilation

What is the Purpose of a Greenhouse Ventilation?

Greenhouses are great places to grow plants. But, greenhouses are notorious for being hot and humid. If you live in a climate where it's too cold outside, you might think twice before building a greenhouse. After all, you'd probably prefer living inside during wintertime. Unfortunately, though, greenhouses are prone to extreme temperatures. That's why you need to install proper ventilation systems.

What Does Good Ventilation Mean?

Good ventilation refers to the amount of air flowing into and out of your greenhouse. Without adequate airflow, moisture builds up inside the structure. Moisture causes mold growth which leads to unhealthy conditions. Mold spores spread throughout the house and contaminate food products. Additionally, mold grows on walls, ceilings, floors, and windowsills. All of these areas must be cleaned frequently to ensure that no mold spores remain.

Is Ventilation Important?

Yes! Proper ventilation is essential for healthy plant growth. Plants thrive in cool environments. If you fail to ventilate properly, your plants will suffer. Furthermore, poor ventilation makes it difficult to control pests and diseases. Pests and disease organisms thrive in warm and moist conditions.

What Are Different Types Of Greenhouse Vents?

There are two main types of vents - horizontal and vertical. Horizontal vents are installed along the sides of the greenhouse. Vertical vents are placed near the roofline. Both types of vents create airflow by allowing fresh air to enter the greenhouse and stale air to exit.

Which Type Works Best?

Horizontal vents are ideal for growing vegetables indoors. Because they run horizontally across the side of the greenhouse, they force air to travel vertically. This creates a natural draft that pulls cooler air towards the bottom of the structure. Fresh air flows upwards creating a cooling effect. Meanwhile, warmer air rises and escapes through the roof.

Do I Need More Than One Vent?

It depends. If you plan to grow tomatoes, peppers, cucumbers, eggplants, melons, squash, pumpkins, or gourds, you'll need multiple vents. Each type of vegetable requires specific amounts of light and humidity. Too much sun exposure will cause leaves to burn. Likewise, too little humidity results in wilting.

Can I Install My Own Vent System?

Of course! You can purchase commercial greenhouse vents or build your own. Commercial units are expensive. However, they're built specifically for greenhouses. They're engineered to withstand strong winds and extreme weather conditions. DIY kits are cheaper and simpler to construct.

The Importance of Purchasing a Quality Greenhouse Ventilation System

Greenhouses are great places to grow plants. But, they're also hot environments which makes it important to ensure proper ventilation. If you live in a warm climate, you know that greenhouses become extremely humid during the summer months. This causes mold growth and mildew problems. Fortunately, there's a solution to this problem called greenhouse ventilation.

What Does Good Greenhouse Ventilation Look Like?

Good greenhouse ventilation systems circulate air throughout the structure so that moisture doesn't build up inside. This prevents mold and mildew from forming. Additionally, good ventilation systems reduce humidity levels by allowing fresh air into the greenhouse. Without adequate ventilation, the temperature inside the greenhouse rises quickly causing plant stress.

Is It Difficult To Install A Good Greenhouse Ventilation System?

Installing a good greenhouse ventilation system isn't difficult. All you need to do is purchase a ventilator unit and connect it to your existing exhaust fan. Then, simply turn on the exhaust fan and let the ventilator run continuously. Once installed, you shouldn't notice any changes in the environment.

Do I Need Professional Installation Services?

It depends on whether you plan to install the ventilation system yourself or hire professional installation services. If you choose to do it yourself, you'll only need to follow the instructions provided by the manufacturer. Otherwise, you'll need to call a contractor to perform the installation.

Which Type Of Ventilation Systems Are Available?

There are two main types of greenhouse ventilation systems: passive and active. Passive systems rely on natural convection currents to circulate air. Active systems utilize fans to force air through vents located around the perimeter of the greenhouse. Both types of systems are effective at reducing humidity levels and preventing mold and mildew formation.

Can I Get An Estimate Before Installing My Own Greenhouse Ventilation System?

Yes, you can get estimates before installing your own greenhouse ventilation system. Just ask your local hardware store or building supply company where they recommend getting a quote.

Features to Look For When Buying a Greenhouse Ventilation

Greenhouses are great places to grow plants. But, they can become hot and humid during summer months. If you live in a warm climate, it's important to install proper ventilation systems so that your plants stay healthy and happy. Here are some features to look for when choosing a greenhouse ventilation system.

Ventilation System Size

The amount of air circulation required by your green house depends on its size. Smaller green houses only require a few fans. Larger ones might need several dozen. Make sure that you purchase enough fans to meet your needs. Otherwise, you risk overheating your plants and damaging them.

Fan Speed

Fans speed determines how fast air circulates around your greenhouse. Fans with higher speeds circulate faster. However, they produce more noise. Conversely, slower fans create less noise but circulate less air. Choose a fan based on your preferences.

Air Flow Direction

Your greenhouse has two sides - the front side where you enter and exit, and the rear side which contains your growing beds. Air flows into the greenhouse from the outside and exits via the roof vents. Depending on whether you prefer natural light or artificial lighting, you'll either want to position your fans towards the front or the rear of your greenhouse.

Power Consumption

Some ventilators consume power continuously. Others shut themselves off automatically once the temperature reaches a certain level. Consider purchasing a model that consumes minimal electricity.

Installation Type

There are three main installation methods for greenhouse ventilation systems. First, you can mount them directly onto the wall. Second, you can hang them from the ceiling. Third, you can attach them to the ground. Each method offers advantages and disadvantages.

Mounting Method

Mounting your greenhouse ventilation system directly to the wall requires no tools. However, it limits airflow and makes it difficult to access the unit. Mounting it to the ceiling eliminates the problem of limited airflow. However, it does limit accessibility. Lastly, mounting it to the ground prevents you from moving it laterally.

Hanging Methods

Hanging your greenhouse ventilation system from the ceiling allows you to adjust the height of the unit. Additionally, you can reposition it whenever needed. Hanging it from the ceiling also reduces the possibility of breaking it accidentally. However, hanging it from the ceiling restricts airflow.

Ground Installation

This option lets you relocate your greenhouse ventilation system whenever necessary. Ground installations eliminate the problems associated with the previous two methods. However, installing it underground increases the chances of flooding.

Different Types of Greenhouse Ventilation

Greenhouses are great places to grow plants. But sometimes it's hard to breathe inside the structure. That's why greenhouse owners must install proper ventilation systems. If you own a greenhouse, here are three common types of ventilation systems that you might choose from.

These vents are installed along the roofline of the greenhouse. Horizontal flow vents are beneficial because they let air circulate freely throughout the entire greenhouse. Air flows horizontally across the roof and into the interior where it mixes with warm moist air. Then, the mixture of hot humid air rises and exits via the vent.

The main drawback of horizontal flow vents is that they only cool the upper portion of the greenhouse. Because the air doesn't travel far enough below ground level, the lower part of the greenhouse remains warmer than normal. Consequently, the temperature of the soil tends to rise which causes mold growth.
