How do you calculate lighting? I tried using the app but it doesn’t seem to consider the varying length of day where I live. I tried an online calculator and it seems I’m missing something. My plants all live within 1 foot of the window. I also have a smaller area on a south facing window which I can use for my plants. In the winter I’ll have to supplement but trying to figure out what plants to put where to start. I just got a bunch of new plants so some need to move.
