Gradual light decline from 18/6 or instant 12/12 switch pros and cons

Indoors growers are focused on get the best weed on the shortest amount of time. So the majority ( if not all) do an instant switch, someone also like to do also a dark period to stimulate the flowering to start faster. If you don’t do right the gradual change you can stress your plant to be hermi and also you lose time doing that way. a light that simulates sunrise and sunset is much more useful if u want to simulate the real environment✌️🏽
