Whats To HOT Help

Hi all got a quick question is 40c to hot my tent is usually stays at 28c lights on and 23c when there off but lately with the hot weather its hitting 40c in my tent which is 1.2m 1.2m 2.0m and thats with my fans running.so can anyone tell me whats to HOT...

Temperatures should be between 70-80 degrees F when the light is on. When the light is off the temperature can drop to the low 60's and have no negative effect on the plant.
The temperature should never go below 60 degrees or above 90 degrees (even for short periods) or growth will slow down. If these extremes are exceeded the plant may be permanently damaged or killed.
Humidity should be between 40-60 percent relative humidity. Use a hydrometer to measure humidity if you think your grow area is out of range. A humidifier can increase humidity and a dehumidifier can be used to lower humidity.
hope this is of any help
