Temperature
Temperature is controlled by any heating unit or natural sunlight that your room receives. Normal households have suitable temperatures for growing cannabis in. The best meter for temperature control is the human body. If you find it is too cold in your grow room then so will your plants. 75 degrees Fahrenheit is what you should aim for. Slightly warmer rooms do help plants to grow a bit quicker. Use a thermometer to analyze your room’s temperature. If too cold, turn on the heating. If too hot, open a window and maybe even use a fan.
