As experienced cannabis cultivators know, achieving maximum yield isn't just about genetics and lighting. The invisible interaction between temperature and humidity—known as Vapor Pressure Deficit (VPD)—plays a crucial role in plant health, nutrient uptake, and final harvest weight.

Whether you’re growing in a small indoor room or a large-scale commercial facility, understanding your lighting needs can be the difference between average yields and top-shelf flower.
