For any greenhouse to be successful, maintaining the appropriate temperature and humidity is crucial. Therefore, its air conditioning system is a crucial component. In this article, we will examine the essential factors to consider when selecting the right greenhouse air conditioning system, including cost, efficiency, and size.
Determine The Size Of Your Greenhouse
Selecting the appropriate air conditioning system for your greenhouse depends on its size. For larger greenhouses, a more robust system is necessary to regulate the temperature and humidity levels consistently. It is crucial to choose the right system to ensure optimal growing conditions for your plants.
To determine the appropriate size of your air conditioning system, measure the square footage of your greenhouse. Additionally, consider any future expansion plans you may have for your greenhouse as this will also impact the system size.
Determine The Internal Load Of The Greenhouse
In addition to considering the size of the greenhouse, the load inside the greenhouse is also an essential factor to consider when choosing a greenhouse air conditioning system.
What is the limitation of the greenhouse? For example,
- How many kinds of plant lights are there?
- How much heat is there in plant light products?
- How many plants to grow indoors?
- How much water do you boil every day? (The calculation method of watering amount = watering amount/number of plants x number of plants.)
- What are the target temperature and humidity?
Consider The Climate In Your Area
Five steps let you have excellent grow room climate control.
Each stage of plant growth requires a different temperature. A simple window AC unit is sufficient for hobbyists or growers raising a few plants. Unfortunately, though, they could be more efficient. A team with the capacity required for late flower loads with enough turn down to handle a grow in the earliest stages of veg is excellent for commercial cultivation. Meanwhile, the influence of ambient temperature on air conditioning work must be addressed.
Keeping Air Moving
Keeping air moving in our grow room serves two purposes: First, It helps with mold prevention, and second, it helps build stronger stems and branches on your plants. If you're unfamiliar with transpiration, think of it this: Your plants soak up water at the roots, and the water moves through them. That water doesn't disappear, evaporating through tiny pores in the leaves.
The circular movement inside the grow room breaks up the boundary layer of air that, otherwise, would hang around your leaves, keeping them too moist and vulnerable to mold and fungus.
Think about Controlling Humidity
Overall, Humidity control is one thing people miss, but it is one of the most significant challenges of modern commercial agriculture. Lots of people think of it as mold control, but another good reason to have a handle on your humidity is to influence your plants' transpiration rates.
Control Your CO2 Levels
CO2, or carbon dioxide, is the one nutrient that could be included under the umbrella topic of climate control. If a grower uses high-powered lights and the plants get sufficient water and nutrients, they can use more CO2 than the environment can naturally provide. This is why it's essential to think through your whole growth process. If CO2 is a limiting factor, consider building it into your climate control system.
Growers should pay attention to light when they think about plant health and indoor growth, but one element can get missed: Most lights add lots of heat to the room so you can include that consideration as part of your climate control. For example, metal-halide and HPS (or high-pressure sodium) lighting systems can add a lot of heat and elevate your room beyond the 20-degree. But, of course, lighting dovetails with temperature control, and you'll have to think everything through.
A climate control plan is necessary to expand or build a new facility. How many plants per room, water per plant per day, power, number and time of plant lamps, cooling, dehumidification capacity, Co2 Level and fresh air, etc.
Choose the Correct Type of Greenhouse Air Conditioning System
The environment and specific needs of our region need to be considered when choosing the right air conditioning system for our greenhouse. There are three most common styles, including evaporative cooling, air cooling, and water cooling systems.
1. Evaporative cooling systems are ideal for hot, dry climates.
2. The air cooling system is more suitable for medium temperature.
3. The water cooling system is the most efficient, but requires continuous water supply.
Consider Additional Features - Humidity Control
In addition to energy efficiency, it's essential to consider additional features when choosing a greenhouse air conditioning system.
One important feature to consider is humidity control. High humidity levels should lead to mold and mildew growth, damaging your plants and reducing their yield. Look for systems with built-in dehumidifiers or humidifiers to help maintain optimal humidity levels in your greenhouse.
Additionally, consider strategies with programmable thermostats, which allow you to set specific temperature and humidity levels for different times of the day or night.
