A general recommendation is that the temperature be held constant in the range of 21-23Â°C (69-73Â°F). In summertime when outdoor temperatures are higher it is advisable to keep air-conditioned offices slightly warmer to minimize the temperature discrepancy between indoors and outdoors.
Keep this in mind when building your grow room. When the light is turned on, an ideal temperature for the cuttings and seedlings is between 68ÂºF and 77ÂºF (20ÂºC and 25ÂºC). As the plants get older they can evaporate a little bit more and the temperature may increase to a maximum of 82ÂºF (28ÂºC).tâs also a good idea to get one with a temperature sensor on a wire, so you can hang the display outside your grow room, and can see the temperature when the lights are off. Always measure the temperature in the shade, and at various places in your growing room. Provide good air flow by placing several fans.
