                                                                                      If you’re new to cannabis seed collecting, you’ll need to start with learning the difference between 12/12 photoperiod cannabis seeds and autoflowering cannabis seeds. Whereas auto seeds have been bred in a way that means they will automatically begin to flower after a certain amount of time, photoperiod seeds rely on a change in light cycles in order to ‘know’ when to flower. Photoperiod marijuana seeds tend to rely on a 12/12 cycle of lighting, with 12 hours on and 12 hours off – hence the name! The benefits to collecting 12/12 photoperiod marijuana seeds include being able to add feminised or regular seeds that are known for being cloneable, high-yielding, and generally of a higher value to your collection.

                                                                                      Here at Seed City you’ll find a huge choice of photoperiod cannabis seeds to choose from, including famous favourites such as AK 47, THC Bomb, Euforia, LSD, Purple Haze, and more! With our price match guarantee you’ll get your photoperiod weed seeds at the lowest prices anywhere online!
