Thing is UK is too cold to start with (april) so wanna have ladies ready so soon as it get hot enough can stick them outdoors. Therefore still allowing time in august to cut the sunlight down with a tarp so get good bit of strong sunshine (if we're lucky!) to flower up before it starts getting...
Is there any problem with starting seedling - once they are few inches tall cut down the light - when sex shows ditch the males and increase the light again to make ladies grow bigger then reduce the light again when they are a decent size?
Any problems with starting indoors then moving...
