Delta9’s Cannabis Temperature Guide
If you want to have a high quality bud, you need to figure out the right cannabis temperature you have to grow it at. It’s important to note that you have to find as well as maintain an optimal temperature. Because of that, we created a quick guide to help you identify the right temperatures depending on the situation.
Vegetative and flowering stage
If your buds are in the vegetative stage, you will need to keep a temperature around 21ºC when the lights are off and around 27ºC or so when they are on. The flowering stage will require a cannabis temperature which is a little lower. The grow room should be around 20ºC in the dark and 26ºC with the light on.
Another thing to note is that even if there are cannabis temperature fluctuations between the day and night, they should be kept at under 6 degrees.
Keep in mind that you will not be able to obtain these temperatures and fluctuations naturally most of the time, so focusing on a good grow room setup is a good idea.
If it’s too hot
High cannabis temperature is not ok at all. This is why you need to find a good set of grow room tools that might be able to help you with these. Some helpful tools include:
- An air conditioning unit will be helpful if you want to keep the temperatures low. When used correctly these things are great.
- A swamp cooler will raise the humidity in the room, very useful during those hot and dry times!
- Using a dimmable ballast will allow you to turn your light to a cooler setting if you have a random hot day.
- Light cycles can be set so that the lights are on when the ambient temperature is at its coolest.
- CO2 enrichment can be an option as plants perform better in slightly hotter temperatures with CO2. However, it’s very expensive!
- Use a good intake and extractor fan as they will be able to provide a high quality air circulation and they will also bring in some fresh air within the premise as well!
If it’s too cold
There will be times when the cannabis temperature will be way too low, around 15ºC or less. If that’s the case, you will have to use some grow room tools like:
- A grow room heater will help you increase the air temperature. Oil filled models work best as they will not boost the air pressure.
- Fan speed controllers are great tools, if the grow room is too cold the controller will slow down the extractor fan.
- Increasing the temperature of the air that is brought in by the intake fan if possible. This will play a major factor in the environment.
- A digital ballast with a super lumen option can help as they can be turned up an extra 10% than a magnetic. 660 watts etc.
Dialling in the best cannabis temperature can be quite frustrating. That’s why this guide will be able to help you find the right temperatures and how you can adjust things for any temperature changes. Give these ideas a shot in order to get the best results!
