There is a big difference between letting a child smoke & letting them grow. It seems like the OP has a pretty col dad & shouldn't take the p*ss by keeping the plants on the family property. Find a bit of waste ground or the like and run the risk of get caught there. Either that or as said before kill the plants & wait till you are earning enough to risk your own home.
