The total hours of light, for example; sun up at 6am and down at 6pm is 12 hours of light and 12 of dark a 12/12 or blooming photoperiod. Photoperiod simply means light cycle, photo means light and period is obviously the amount of time. 12/12 is enough to flower as you would know but not enough to veg, that requires I would think a minimum of 15 hours of direct light.
No such thing as a stupid question mate, hope this helps.
Yeah cool, so cos of the length days r longer in late October, the 18/6 plants just keep vegging? There is around 13 hrs on the 20th of October increasing by the day, so that is pretty cool, coming from 18/6 to 13/11 and not flowering, that’s perfect for a gorilla grow I’m contemplating
