When you are ready to switch over to flower, you do the 36 hours of darkness at the beginning. This will convert Phytochrome Far Red to Phytochrome Red signaling your plants that it’s ready to flower. This process usually takes 2 weeks if you only switch to 12/12. With the 36 hour darkness soak you give your plants a head start and reduce the time it takes to signal your plants to flower. You only do this at the beginning. Since you have already induced flowering @McLovin777 you cannot do this and it is not beneficial to do it during the flowering cycle. I think the darkness at the end of the flowering stage is used to stress the plant, and therefore producing more trichromes @Majiktoker would know more about that.
To sum it all up, the basics are this: Phytochrome Far Red actively keeps your plants from flowering. Once there is a low enough amount of Phytochrome Far Red, your plant will start to flower. This decrease can only come from long periods of darkness without any interruption.
So after the 36 hour soak and one 12/12 cycle I am already seeing some very small pistils forming.
Sorry it’s blurry. It was taken from an Oboma phone. Maybe the new Trump phones will be better LOL
