the odor will depend on the strain, temps, etc ... a lot of strains will stink up your whole house, yup ... you can force flowering at any point in the plant's life, by settimg your light cycle to 12-hour days, however, yield heavily depends on maturity of the plant ... I personally, don't induce flowering until the nodes start alternating, on the main stem ... (usually after the 5th or 6th sets) ... the alternating nodes indicate the plant is mature, and ready for pollination ... good luck :smokin:
