Frequently Asked Questions (FAQ)

What is DLI?

DLI stands for Daily Light Integral, which measures the total amount of light received by a plant over a 24-hour period.

What is VPD?

Vapor Pressure Deficit (VPD) is a measure of the difference between the amount of moisture in the air and the amount of moisture the air can hold when it's saturated.

Why is VPD important for cannabis cultivation?

Maintaining the right VPD is crucial for optimal plant growth, as it affects transpiration rates and nutrient uptake.
