hey there BwP, yeah so with every strain you'll find different "phenotypes" aka different "types" of plant, shorter, longer, bushier less bushy, that sort of thing. So to answer your question, yeah it's very possible. About your second question about the flower time, you should always do what the plant says not what the breeder says. Often times the breeder will give a flowering time a couple weeks or more shorter than the actual flowering time you'll experience. The best way to check if your plant is ready to harvest is to check the trichomes with a magnifier or use the pistil method (less precise!). Hope this helps ! 🚀
