When you are growing your cannabis plants, it’s not only important to use excellent high performance lighting, but you also must keep the temperatures within a good range.
You’ll find that when your cannabis plants are performing photosynthesis, they will not be able the function well if they are below 68 degrees.
The plants take in light, water, and CO2 and they create sugar and oxygen. When those plants are too cold, they won’t be able to move the sugars to where they need to be and this can cause major problems for the plants. Your plants can become stunted or damaged when the temperatures are not right. If the temperatures go above 85 degrees this can also be devastating for the plants. While the plants might not die necessarily, they may start to grow a great deal slower and they certainly won’t be able to produce good buds if they are too overheated. This is why it is important to use fans in your grow room to keep the temperatures stable and it’s essential to use a ventilation system fan to vent out all of the overheated air from the growing area. Overheated cannabis plants will commonly suffer from things like spider mites, root rot, nutrient burn, wilting, and over stretching. You certainly don’t want these issues if you expect to have a good product during harvest, so make sure you keep those temperatures within the suitable range! The best range would be between 68 and 77 degrees so that your plants will be as healthy as can be.
