Temperature Control
The temperature and humidity in grow space will need too be controlled. The ideal temperature for cannabis growth is about 75F (24C). The ideal humidity for cannabis growth is 50-70 percent for pre-flowering and 50 percent for flowering plants. Chances are the environment will need to be heated or cooled a little to maintain the ideal temperature and humidity. Often a ventilation fan is all you need to keep the temperature and humidity perfect.
