Ideal Temperature and Humidity For Grow Room

Growing cannabis successfully needs specific techniques, tactics, and tools. Knowing the best grow tent temperature will be a good start.

Ideal grow tent humidity and temperature changes depending on the stages of the plants’ life.

Cloning calls for high humidity and temperature than vegetative growth, and flowering plants have different ideal atmospheric conditions as well. For mastering the art of growing cannabis, having the proper environment at the right time is the most important requirement for success.

You can control the weather inside your grow tent. Creating the environmental conditions that are best for growing healthy plants is all in your hands. Mainly, you have to keep in mind the best conditions for growing marijuana in terms of humidity and temperature.

On that note, here are the ideal conditions to help you.

The Ideal Humidity for Cannabis Growth

The best range of humidity levels varies between 40% to 70%. If it’s higher or lower, the cannabis plants may suffer some problems.

However, bear in mind that the precise level of humidity changes depending on the growth stage.

Following that, here are the ranges of humidity level according to the growth stages:

  • Sprouting Stage

During this season, give your plants around 65 to 70% humidity.

  • Vegetation Stage

When leaves start growing, reduce the humidity every week by 5%.

  • Flowering Stage

Now, retain the humidity level at around 40 to 50%.

  • Harvest Stage

Before harvesting season, reduce the humidity level by around 30 to 40%.

Due to multiple reasons, you need to reduce the plant’s humidity levels at every stage.

The Ideal Temperature for Cannabis Growth

The ideal temperature for cannabis growth ranges between 68 and 77-degree F. The temperature difference between nighttime and daytime temperature doesn’t exceed 18-degrees F.

Following the ideal temperature ranges is important to keep your cannabis healthy.

When the temperature reaches above 80-degrees Fahrenheit, the growth of cannabis accelerates. Thus, you’ll need to increase the watering and fertilizing.

During the Seedling stage, keep the temperature from 66 to 77 degrees F. During the vegetation level, keep between 71 and 81 degrees F.

When the flowering stage arrives, keep the temperature from 68 to 78 degrees F. And lastly, when harvesting arrives, keep it between 64 and 75 degrees F.

Controlling the Temperature and Humidity In a Grow Tent

For controlling the humidity and temperature in a grow room effectively, first take a good look at it. Is it ventilated? Is it a climate-controlled space?

It must be fairly sealed off for better control of the environmental conditions. If you use HPS or high-pressure sodium lamps, you may already have an extractor or tent fan setup.

The HPS is good, but it may cause heat and electricity. Due to this, you must be very careful while controlling the temperature of the grow tent to keep it cool.

LED lights are better than HPS. This way, there would be minimal waste of power, and you may need to set up a thermostat during the winter to keep the grow room warm.
