Caught by whom,a mother,a father,a sibling,the police ??.
The only way anybody is going to get caught growing 2 plants indoors is if they put a flashing neon sign on the front porch saying "Im Growing Weed Here"
or to go to the local police dept & turn their self in out of guilty conscience.
Ofcourse mom could always spot the grow & flip out too
Unless you can visit your grow 3 times a week & spend a decent amount of time working on your garden then inside is much easier for a new grower.
