Kinda? Cannabis isn't a perennial, it's an annual plant. Once they flower, their life cycle is technically over.
But photos (not autos) can be revegged to save the exact genetics of the plant. That front right plant has a few good stems you can cut. But the other plants may need to go back into 18/6 light cycle for a while to see if you can get them to grow a few stems, then cut those stems and use them to grow a new plant.
Just look up revegging cannabis for endless guides on how to do it.
Perfect, it's a very fun project! If you already know you have a good plant and want to keep using it forever, you can keep it in veg and just pull stems off them to flower, a mother plant.
But sometimes you'll be growing from seed and just have absolutely insane genetics, keep half a dozen stems when you trim or lollipop, then dip them in a little bit of rooting gel or powder and slide them in a rapid rooter or something. You don't even need a ton of room or light, just keep them moist.
