ditto bejay. They get all fucked up when we tried that. If you can start indoor you can schedule to grow mothers and have clones ready to plant as soon as the ground is warm and no chance of frost. Also, you can plant clones or seed early like that and still germinate another crop and get them in the ground about mid summer. Smaller yeild but still finish about the same time as the early planting. I've read of people using black covers to start flowering early outdoors, but I don't know how sneeky that is...
