Lumens are for Humans; PAR is for Plants

Learning about hydroponics was my COVID project. It was something I had wanted to learn for a long time and this was the perfect opportunity. I decided early on that a grow light would be my primary (and biggest) investment. Since then, I have experimented and explored all kinds of different growing methods and systems and I still think choosing a grow light carefully is the most important step. This post is the result of my own deep-dive into grow lights and my explanation of how to best use artificial light sources for autotrophic (self-feeding - aka photosynthetic) organisms.
