Can you recommend the optimal temperature levels for my cannabis plants? I want to ensure they are growing in the right environment.

The optimal temperature range for cannabis plants differs depending on the growing stage. Each phase has its own ideal temperature range. It’s important that growers take care to maintain conditions suitable for the phase their cannabis plants are currently in.
The vegetative stage is the phase of growth where a cannabis plant develops roots, stems, and leaves. During this stage, the optimal temperature range is typically between 70 to 85 degrees Fahrenheit (21-29 degrees Celsius). To achieve strong and healthy plants, it’s essential for growers to make sure the temperature range does not drop below 65 degrees Fahrenheit (18 degrees Celsius) or rise above 90 degrees Fahrenheit (32 degrees Celsius). If either condition is met, the plants’ photosynthesis process can be disrupted and cause them to slow or stunt their growth.
Once plants reach the flowering stage, the optimal temperature range should be reduced to 70-80 degrees Fahrenheit (21-26 Celsius). Too much heat can cause plants to produce fewer buds, while temperatures below 65 degrees Fahrenheit (18 Celsius) can stop flowers and buds from forming. Utmost care should be taken to maintain temperatures level during this stage.
During the final stage of growth, the drying and curing phase, the temperature range should be even lower. Humidity should be between 45-55% but the temperature should be kept around 65 degrees Fahrenheit (18 degrees Celsius). Higher temperatures can cause the flowers to dry too quickly and degrade the quality of the buds, while lower temperatures can cause them to become far too moist and potential encourage the growth of mold.
It’s important to keep indoor temperatures monitored and for outdoor growers to take climate into account when deciding when to harvest their plants. Knowing the ideal optimal temperature range for each stage of cannabis growth can protect plants from slow growth, bud degradation and mold.
Apart from temperature, humidity should be kept at the proper level for each stage of growth as well. Humidity levels play a huge role in plant health, especially during the flowering stage, when humidity should be kept around 40-50%. During the drying and curing phase the humidity should be lowered to 45-55%. Too much humidity can cause moisture to build up on the surface of the buds and too dry of an environment can cause buds to dry out prematurely.
When it comes to temperature and humidity, cannabis plants can be particularly sensitive, so it’s essential that growers keep careful watch to ensure their plants are receiving the optimal level of care. Making sure to maintain the proper temperature and humidity levels for each stage of growth can help ensure a successful yield of healthy, high-quality buds.
