bro for serious.
if you really wanna do it, DO IT RIGHT!
i dont give a shit if you wanna grow in your mom's house, in fact i say go for it! but don't get caught.
you are a teenager so you will be sloppy, you will make a mistake and you will get caught by your mom no matter how discreet you try to be, i'd bet a rather large sum of money on it.
but if you're gonna get caught you might as well grow a smokable quantiy of bud. seriously a 23 watt light may not actually support a plant through flowering, like not only will you maybe get enough bud for ONE or TWO shitty bowls tops but the plant will probably just die.
now let's look at this practically.
there are ways to do this stealthily, i am a grown ass man and i still have to hide my grow (i have roommates and i live in an apt so i have to be discreet when the pest control guy comes to spray and for apt inspections etc.) so i took apart a dresser and sealed it up added an HPS light and ventilation.
check through the site check the areas on how to build a stealth grow box you can take just a rubbermaid tub like you would use to store stuff put 4-6 of those 23w cfl's in there with a little ventilation and some mylar and you can grow a plant or two no problem. actually a grower on this site uses three large rubbermaid tubs stacked together with 6 x 42 watt CFL's and he pulls out 4 oz's a harvest.
just get a simple stealthy box that you can put in your closet and throw some clothes over that your mom won't be suspicious of, make it light sealed and low noise.
all you need is soil water light, and patience. just remember that the plant is going to get a minimum of 1 or 2 ft tall, and that's if you start flowering after a week or two. you can prune it to make it shorter and bushier as well. that's the cool thing about cannabis, you can grow it really stealthy if you are creative.
you probably aren't creative, you probably won't listen to any of this because you're a kid. who cares, what i tell you is true, do what i say.
oh and BTW dont' tell ANYONE about your grow. you've probably already told your 3 or 4 pot smoking buddies about it. loose lips sink ships.
