You cant have critisism without judgment. So with that said, you are completly unprepared and under educuated on the matter to even attempt to grow.
1. Dont try to secretly grow pot in your parents house, i doubt you could pull it off without getting caught. If your still living in your parents house and trying to avoid notice i imagine your a teenager. You should be more concerned with going to school not getting stoned.
2. One cfl is not nearly enough for 1 plant let alone 3. People here use 1000's of watts of lighting, not that thats all needed but if your planning on one day upgrading to a single 27w bulb for 3 plants then your gonna be in for a big dissapointment. At a minimum (and i mean minimum) you will need 50w/sq. ft of grow area.
3. The fact that you think you can just stick a seed in a cup under a lightbulb and produce some chronic is almost insulting to everyone here who spend countless dollars and hours growing pot and putting the information up here for others to learn from.
So if youu dont want others to pass judgment, then maybe do a little reading before asking the most basic questions, as there is a very very high chance they have been answered on here 1000's of times previously.
That aside, nothing personal, i hope your grow fails as someone of your age, maturity, and in your living situation isnt nearly prepared to deal with the repecusions of manufacturing a schedule 1 drug.
Heres my advice, finish school, read this website till you cant read no more, absorb all information, and once you are mature enough, and in an appropriate situation where you could even consider growing anything worth your time and money, then give it a go.
