Depends if you're planning on growing inside or outside. If you're in an area where it's illegal it's going to be much harder to do. Also try and find out what strain it is that you would be growing. Different strains have different yields and plant sizes. If you're going to be growing indoors you can't have anything too large, and definitely cannot have a lot of them because of the heat signature your house will put off. Law Enforcement agencies around the US have been known to fit aircraft with thermal imaging cameras to find grow operations from the air. You have to be veerrrryyy careful with this kind of thing.
