Force flower?

You mean like cover the plants with a trash bag or something an hour before it gets dark and then taking it off at night? Every day on seven different plants in three different spots until late august? What happens when I miss a day, hermies? I know people grow pot here and north of here so what is the deal? I know they can't all force flower or use 6 1/2wk strains.

Man I'm so worried that all this work will be for nothing.

Btw I have a morning glory, 2 angel dusts, a DPxS#1, and three bagseeds from local grown kill. I assume the local weed is gonna be ok since its, you know, local, but the others are all 8-10wkers. This blows.
