I maintain mine with a humidifier, while my exhaust fan runs 24/7 with no stagnant airNice. Too many people have no clue how important and how much of a difference VPD makes in your garden. I always see a lot of people disregarding it like it doesn't matter when it's quite literally the most important factor in growth speed, vigor and overall health. After you have good lighting VPD is the very next thing you need to try and perfect to get amazing results providing you also have good genetics.
