question

I smoke about 6 joints a week and i am tired of the weed i am getting. I have a great place to grow in the back shed
i only want to grow what i smoke and how many plants to i need 2? or do i need more due to the male plants and would a 400 watt high pressure sodium light be enough. or what would you suggest

The 400 hps would grow enough for one person. Potsize and Veg time would determine how many plants. Good luck
