When I started to grow plants under artificial lighting, I noticed different growth habits for identical plants growing in the south facing window, natural sunlight, vs the artificial lighting. I had the artificial light on a fixed schedule year-round.
I experimented by changing my artificial lighting to mimic the natural sunlight, seasons, and noticed the plants responded the same way as the plants receiving the natural sunlight.
Flora and Fauna not coming from around the equator follow seasonal cues.
Many Haworthia mainly come from South Africa.
Below is monthly daylight hours for Pretoria, South Africa.
Roughly my schedule.
Do I need to do this? I doubt it. Do the plants need to have simulated seasons? Probably not.
Because it is so easy to for me to set a set the schedule, it is what I choose to do.
