The short and easy method. Get a 600 watt HPS, Germinate the seed and never turn the light off. Let the plant grow until it starts to show preflowers, which will take from 5-7 weeks, then the plant is mature and you can begin flowering by making the plant sit in complete darkness for 12 hours, then the lights on for 12 and on and on you go until the plant is fully flowered and you can harvest it.
