Balancing your grow tent temperature with tent humidity
There is a close relationship between humidity and temperature when it comes to plant health and yield. If this balance is out of whack, your plants will suffer. The key is to hit the VPD sweet spots seen in the chart below.
The green values will give your plant optimal growing conditions because it’ll be able to breathe better and not lose too much moisture to the air requiring excessive irrigation.
The right temperature will also reduce the number of pathogens in your grow tent which will do away with the need for pesticides and fungicides.

The ideal temperature for growing plants indoors in a grow tent sits at around 18-28 degrees on average.
