best temperature for flowering stage

– When the environment runs too hot, adding a top layer of mulch to keep the roots cooler, and watering frequently will help. Keeping the roots from overheating will go a long way to preventing heat damage to your plant.

Plants, unlike most animals, are unable to regulate their own temperature. As a result, they can suffer extreme damage when put into the wrong temperature or climate. Cannabis is no exception.
This usually results in death of the plant. So, as you can see, maintaining and ensuring your cannabis plants stays within a comfortable temperature range is very important. Learn more about how to grow big buds outdoors.

Or turning them on if the room becomes too cool at night. In general, in the vegetative stage, your plants should receive about 18+ hours of light. But it doesn’t have to be consecutive. Playing with your light times can be an efficient way to maintain those slight temperature changes.
The heat from your grow lights can easily get out of hand. And the cost of A/C units can just as easily get out of hand. So, what are some clever, cost efficient ways manage temperatures in your grow room?
However, the acceptable temperature range can vary depending on if your cannabis plant is in a vegetative, or flowering stage of growth. The optimal temperature range for the vegetative stage is typically between 70 – 85. The optimal range for the flowering stage is typically between 65 – 80.
When it comes to growing your own cannabis, there can be a lot of effort involved. Making sure you know the sex of your flower, understanding your soil, light spectra, and moisture control. It can all be quite complicated.
– Change up your light schedule. Grow lamps can get quite hot when run for long periods of time. If you find your grow room getting too hot or too cold at certain time of day. You can try changing your light schedule. For example, shutting off your grow lamps during the hottest part of the day.

– Make sure you are properly insulating your grow box. This is important to maintain warmth if you are growing in colder seasons. You should also use heaters that radiate heat, instead of heat fans. Hot air blowing directly onto your plants can be very damaging to the plant.

Cannabis plants like a temperature similar to humans, or a little warmer — not too dry, not too humid.

The Vegetative Stage: Best Grow Room Temperature
The best grow room temperature during the flowering stage of growth is 68–75 degrees during the day and no more than 10–15 degrees cooler at night. If you’re supplementing with CO2, daytime temps can be as high as 75–82 or so. During flowering, you should lower your relative humidity to 35–45% and even lower (30%) for the last couple of weeks before harvest. This will help you avoid issues with mold, bud rot and PM (Powdery Mildew) that can arise in higher humidity.

For a lot of indoor growers, that is all you need to worry about. If it feels too hot or too cold for you in your grow area, it’s probably too hot or too cold for your cannabis plants as well.
The Flowering Stage: Best Grow Room Temperature
During late flowering, improvements to overall quality can be achieved by keeping temps and humidity as low as possible. Humidity under 40% RH is ideal.
Basic Hygrometers and Thermometers
Room temperature with lights on should be 18–24°C. Increase the difference between day/night temps by up to 10°C for even better results.

Seedlings and clones respond best to higher humidity levels of 65–75% RH as root systems are not yet well-established. Clones and young plants take in moisture through their leaves.
Room temperature with lights on should be 20–25°C. Lights off, 15–20°C.
