Seconded! I'm very early into a first grow and it's so exciting seeing your first baby leaves growing. It finally feels like I'm putting my college physics to use and building on it. You're trying to control the environment, with many different factors, as perfectly as you can. To do it well, you have to understand the principles behind each different factor. E.g.: In controlling temps and humidity which is important for plant respiration, why does a lower temperature hold less moisture? Heat is kinetic energy, and a higher temp (more heat) means more molecules on avg have enough energy to become a gas.
