Forcing plants under sun into early flowering???

Aslong as they get 12 or less hours of light every day they will begin to flower. So yeah if you covered them up or moved them somewhere in the dark you'd be fine I'd imagine, seems like that'd be a bit tedious though every day.

why dont you just wait till they flower naturaly? they should be flowering already depending on were you live but in the u.s they are flowering now!just close the curtins at night or move them to another spot were they get the sun but not the street light and PLEASE be patient or you will regret it. good luck and happy growing
