Ideal Cannabis Humidity and Temperature 

Why Ideal Greenhouse Humidity and Temperature 

Considering ideal greenhouse humidity and temperature for happy and healthy Cannabis crops. Without them, nothing will grow properly or might be the entire crops, money, efforts, and time will completely be destroyed. Growers love to grow cannabis all year round. So it is very much possible to grow them in a greenhouse or grow room. 

But the temperature and humidity in the greenhouse are dependent on what kind of plants you grow. By maintaining a greenhouse in optimal conditions means growers can benefit from healthy cannabis whatever the season is. 

It is difficult to create a perfect cannabis temperature and humidity. But with the help of the best equipment, growers can control to maximize plant growth. Regardless of the crop type being grown, a grower always tries to achieve requires controlling the same variables. They include temperature, cannabis humidity, light level, carbon dioxide, airflow, and air distribution. 

The Challenge of Reducing Cannabis Humidity 

When it comes to controlling ideal greenhouse temperature and humidity, humidity is a challenging variable, especially for dehumidification. Being a grower, if you try to remove moisture from the greenhouse, it will lead to many challenges. And removing moisture can be done through proper ventilation. 

When we talk about the traditional method to reduce greenhouse humidity is based on opening the greenhouse and injecting dry air from outside into the greenhouse, which is time-consuming and sometimes not effective. Furthermore, growers spend huge amounts of energy reheating the greenhouse after ventilating to maintain optimal growing conditions. Once warm, humid air leaves the greenhouse, it releases water vapor and heat, and losing heat means wasting energy. 

Hence, reducing humidity from the greenhouse sometimes becomes difficult. Using a greenhouse or grow room HVAC is an ideal solution. 

Indoor Growing Environments

Cannabis plants go through a series of stages to grow properly and mature. And those different growth stages need a different amount of light, temperature, nutrients, and water. For a perfect and healthy crop, it’s essential to know these stages with the best HVAC for a greenhouse. One can get the best humidity and temp for cannabis. Generally, cannabis prefers a temperature approx 20 to 25 °C and at the time of flowering, cannabis plants’ need an ideal temperature between 18 to 20 °C . They can live in lower and higher temperatures, but it is important to control the heat for maximum growth and potency and prevent crops from molds and mildew. 

Depending on the stage of growth, size of the room, pot plants capacity, and one should buy an ideal grow room ac unit to control the temperature. If the conditions are too humid, it can lead to disease, molds, and fungus, and arid conditions can retard the growth of your pot plants. One of the best grow room cooling systems will determine the humidity in your grow room and help you achieve the right humidity level. Depending on the conditions outside, opening or closing the entrance to your grow room can adjust the humidity for the perfect balance.

Seedling Stage

Seedling is the beginning, and in this stage, humidity for weed plants’ seedlings and clones like high humidity levels of approx 65-70%. Temperatures with lights should be approx 20-25 °C and if lights off 4-5 °C lower.

In this stage, the root system is not established. Hence high humidity levels will allow them to water intake through leaves. 

Vegetation Stage

Low humidity during veg is necessary, and the level needs to be lower by 5% each week, and its range must be 40-70%. Here, the temperature should increases slightly to approximately 22-28 C°, and if lights are off, it must be 4-5 C° lower.

At this stage, roots absorb more water; and evaporation takes place through leaves to cool the plant.

Flowering Stage

Regarding the cannabis flowering humidity, humidity levels need to be lower to 40-50%, which is highly important. Otherwise, the crops may be prone to several risks. Set the level approx 55% and must know that anything over 60% will be terrible. Regarding the temperature, it’s best to slightly lower temperatures during the flowering stage, and it must be with lights on 20-26 °C .

Late Flowering Stage  

The best humidity for flowering cannabis, if it is late – 1-2 weeks before harvest, brings down humidity levels. Or approximately 30-40% lower daytime, which will improve yield, flavor, and appearance temperatures. And, the temperatures with lights should be approx 18-24 °C (if lights off minus 5-10 °C).

Drying Cannabis Humidity and Temperature

Want to know about the best humidity for drying cannabis? If your cannabis crops are drying, an ideal temperature for cannabis curing humidity in a drying room is 18–24 °C and humidity 45–55 % in a dark room. Within 7–10 days, the branches will look fine instead of bending, and the buds will become healthy. 

Don’t think that humidity and temperature control are complicated and not worth it! On the contrary, it’s generally very easy, and when you have the best grow room HVAC, it will create an ideal greenhouse temperature and humidity. And it will make the entire life cycle of cannabis so smooth. You will get healthy cannabis and profit.
