At the beginning of Week 1 of veg I noticed seedlings were getting a little too leggy for my taste, at first naturally I would typically blame it on light distance but the beauty of having the PAR Meter is I know they were definitely getting enough light. So then I figured it must be too hot with not enough humidity that's causing these seedlings to stretch. So then I researched VPD, Temp & Humidity in relation to plant stage growth. After researching I figured an adjustable humidity dome would be the most optimal way to control these three variables. All I can say is wow seedlings are growing vigorously since I kept the VPD optimal with the other typical parameters of course. I never payed much attention or even knew about VPD until this grow, I used 3 different charts online to measure ideal VPD for plant stage growth along with Temp Humidity & just used the mean average to determine what would be optimal for these little girls. I'm only giving them purified tap water with a little yucca and EM-1 and plan on transplanting by the end of next week.
