Why VPD is Important for Plant Growth

You may have seen that AC Infinity recently added VPD measure into their latest controller 69 Pro, and you may have wondered why that is important? 

When it comes to indoor plant growth, environmental conditions play a crucial role in determining the health and vitality of your plants. One of the most important factors to consider is vapour pressure deficit (VPD), which is the difference between the amount of moisture in the air and the amount that the air can hold at a given temperature. In this article, we'll explore why VPD is so important for plant growth and how you can use it to optimise your indoor growing environment.

Optimal VPD for Plant Growth

To understand the importance of VPD, it's important to first understand what constitutes an optimal VPD range for plant growth. Generally speaking, most plants grow best when the VPD falls within a range of 0.8-1.2 kPa. This range ensures that the plants have access to enough moisture to carry out photosynthesis, but not so much that it causes excess humidity or other problems.

When the VPD falls below this optimal range, it can result in slower growth, reduced yield, and increased risk of fungal growth and other pests. Conversely, when the VPD is too high, it can result in excessive transpiration, which can cause the plants to become dehydrated and wilted.

How to Measure and Control VPD

Measuring VPD is relatively straightforward, and can be done using a hygrometer and a thermometer. By measuring the temperature and relative humidity in your growing environment, you can calculate the VPD using a VPD chart or calculator.

Once you know your VPD, you can take steps to adjust it to the optimal range for your plants. This can include adjusting temperature and humidity levels, as well as adjusting the amount of airflow and ventilation in your growing space. By maintaining optimal VPD levels, you can ensure that your plants have access to the moisture and nutrients they need to grow strong and healthy.

Conclusion

In summary, VPD is a crucial factor in indoor plant growth, and understanding and controlling it can make a significant difference in the health and vitality of your plants. By measuring and adjusting VPD levels in your growing environment, you can ensure that your plants have access to the moisture and nutrients they need to thrive. So if you're looking to optimise your indoor growing setup, make sure to pay attention to VPD and its impact on your plants.

All AC Infinity T series fans that Quick Bloom Lights sells as of February 1st 2023 comes with the option of getting a Controller 69 Pro, this controllers ads the measure for VPD (along with Temperature and Humidity) and brings your grow room to the next level. So, do you know your current VPD in your setup?
