What is the difference between regular, feminised and autoflowering seeds?

Follow

Regular seeds are bred from one male and one female parent and can grow to be either gender, where as feminised seeds are bred to eliminate male chromosomes, ensuring no confusion of gender, and female only plants.

Autoflowering seeds are different to other standard photoperiod strains.  They produce plants whose flowering cycle is not affected by changes in light hours and in turn, the seasons. They will enter flowering stage automatically according to their age, hence the name.
