hell yeah if ur out in the woods man grow outdoors. the sun produces 10,000 lumens per sq foot. i have 2 600 watt high pressure sodiums in my 9x4 flowering area and i only have 5,000 lumens per sq foot. much higher yeilds. i say no on growing at ur parents house. its just immoral man, think of them. everyone always says u wont get caught untill u do. and then your parents are in jail. over you wanting to grow a few plants in THEIR house. if u can get ur own place and CROP THAT BITCH! lol. or do some outdoor research and set up a few pods of 3-4 plants. that would be nice.
