Flowering is when you trick the plant into thinking summer is here and it’s time to produce fruit. As the summer gets on the days start to get shorter right, you mimic this by reducing the amount of hours your plant gets light usually it’s to 12 hours on and 12 hours off this is what we call flowering stage. Before 12 12 you can have lights on 24 hours some people prefer 18 on and 6 off it’s personal preference you can do 20 4 if you like. If you want to pollinate your plants yes you will get shit buds full of seeds good for a new generation of seeds but not what most people want to be smoking I don’t think. There are ways of pollinating a couple of buds just search YouTube. If a seed company says 8-10 week flowering it means you need to grow your plants up 24 hour light then switch there light cycle to 12 12 to start flowering phase and this should take 8-10 weeks to your finish date.
