If you operate any kind of cannabis grow room, the temperature and climate has to be controlled so you can enjoy a good harvest. If this is a hobby, it is more important to know how to handle this than if you are a veteran who might already know many of the things necessary to control climate in the cannabis grow room.

One cannabis crop could go bad, if you don't make concessions for the grow environment. There are some people who really are not aware of what to do to get a better yield. There are some optimization steps that could make a big difference.

The cannabis grow room climate could be the difference between a healthy crop and a scanty crop. We have compiled a few steps that will help you control and improve your cannabis grow climate.

Establishing and maintaining temperature, humidity, and air circulation levels that are ideal for the growth and development of cannabis plants is crucial for controlling the atmosphere in grow rooms.

Here is a quick summary:

Automatic Light Setup

Most cannabis growers do not overlook lighting because they know it makes the harvest healthier and strong. However, there is one component that might be missed. Most cannabis grow room light add more heat and so you have to choose the kind of lighting that will allow you to control the climate in the room. There is lighting equipment that's made with temperature control switches.

While this may be on the more expensive side, it is well worth the investment. There are more cannabis growers choose LED Lights instead while some choose the High Pressure Sodium lighting system (HPS), which is already proven to allow climate control in a cannabis grow room.

To guarantee that plants receive the proper amount of light each day, it's critical to employ high-intensity lights and an automatic light timer in a cannabis grow room.

In addition to ensuring that plants receive the proper amount of light to encourage development and flowering, this will assist in controlling the temperature.

Be Aware of the Surroundings in Your Cannabis Grow Room

Usually the HPS lighting system gives you a 20 degree window to control your temperature and it is possible the reason why many growers choose this option. It allows you to make the room warm enough during the cold weather so your plants won't freeze and it also makes it sufficiently cool not to overheat the cannabis grow room so as to adversely affect your plants.

Due to the effect of the lighting, many indoor cultivators will only have to be concerned about the cooling aspect. For people who are just doing this as a hobby in their home, the simplicity of a window air conditioning unit will do the trick.

However, while it will help to control the temperature, it won't be energy efficient. More importantly, if you decide to scale up your cannabis grow room operation; a window air conditioning unit will not be functional.

Air Circulation & Movement When Growing Cannabis

The air circulation or air flow is also an important factor when it comes to climate control in your cannabis grow room. The air has to keep moving to help prevent mold and to build stronger branches and stems on your cannabis plants.

Once water is soaked up from the root, it moves through the top of your plants, but it evaporates through the leave's pores instead of disappearing.

With the proper air flow inside the cannabis grow room, it prevents your plants from being too moist and susceptible to fungus and mold. You could consider using a couple oscillating fans instead of the window air conditioning unit.

A grow room with enough air circulation can keep its temperature stable and keep hazardous germs and pests from accumulating.

Air may be moved around the grow chamber and vented out using fans and vents.

Humidity Control in a Cannabis Room

You have to control the humidity in your cannabis grow room so that your cannabis plants can perform well and avoid mold. To measure humidity, use a handheld sensor. If your cannabis grow operation is large, then you will need an electronic monitoring system.

This will record the humidity automatically, giving you sufficient time to take other action such as adding dehumidifying equipment and oscillating fans.

Controlling the humidity in the grow room is crucial because too much or too little humidity can have a detrimental impact on the health of cannabis plants.

The ideal range of humidity for growth is between 40% and 60%, which can be maintained with a hygrometer or other humidity management device.

In summary, it is crucial to maintain the ideal atmosphere in a cannabis grow room in order to ensure the health and productivity of the plants.

Controlling the environment in the cannabis grow room involves many critical considerations, including automatic light arrangement, air circulation, and humidity control.

How do I control the temperature in my grow room?

There are many ways to regulate the temperature in a grow room, including:

Ventilation: Install fans and vents to control air flow and temperature to ensure optimum ventilation.

Install a cooling system to keep the grow room cool when the temperature rises.

Heating: To keep the grow room warm throughout the winter, use a heater or a heat mat.

Install a thermostat to have the temperature automatically controlled and maintained within a desired range.

Insulation: To stop heat loss and maintain a constant temperature, insulate the walls, ceiling, and floor.

To ensure the best growth and health of the plants in the grow room, it is crucial to maintain a constant temperature within an appropriate range (often between 68 and 72°F).

What temp should a cannabis grow room be?

The normal temperature range for a grow space for cannabis plants is between 60°F and 70°F at night and between 70°F and 77°F during the day. To encourage healthy growth and avoid mold or pest issues, it's crucial to maintain steady and suitable temperatures.

What is the ideal temperature and humidity for cannabis?

The ideal temperature range for growing cannabis is between 68°F and 77°F, while the ideal humidity level is between 40-60%. However, during the flowering stage, it is recommended to lower the humidity to around 40-50% to prevent mold and disease.

How do you keep temperature constant in a grow tent?

The following actions can be taken to maintain a steady temperature in a grow tent:

1. The tent should be thoroughly insulated to avoid heat loss. Insulate the tent.

2. Use a heater: To keep the tent's interior at the desired temperature, use a heater with a thermostat.

3. Using a cooling system will help you lower the temperature inside the tent if it starts to climb. Cooling systems include fans and air conditioners.

4. Regularly check the temperature inside the tent using a thermometer, and make any necessary heating or cooling adjustments.

5. Seal the tent: Make sure the tent is completely free of any openings or cracks that can allow outside air inside and change the temperature.

These techniques will help you maintain a steady temperature inside a grow tent so that your plants can flourish there.
