VPD combines relative humidity and air temperature, showing the difference between the actual and maximum water content the air can hold at a given temperature.

Do I Need a Humidifier?
Determining whether you need a humidifier for your grow tent depends on your specific growing conditions.
If you live in a dry climate or are growing indoors where heating systems can reduce humidity levels, a humidifier is essential to maintain the optimal moisture balance for your plants.
Cannabis plants require different humidity levels at various growth stages, and a humidifier can help you achieve and maintain these levels consistently.
If you notice signs of low humidity such as brittle leaves, slow growth, or poor nutrient absorption, investing in a humidifier can greatly improve your grow tent environment and overall plant health.
Conclusion
Choosing the right humidifier for your grow tent can significantly impact the health and yield of your cannabis plants. Consider your specific needs, such as tank size, noise level, and additional features, to find the best option for your setup.
