few big plants or many small plants?

if your growing in a area where it isnt a good idea to (if u get my drift) is it better to grow alot of small plants or a couple big ones assuming you get the same yeild from both. i figured that the fewer plants the better reguardless of size. and because i hear you can even get busted for pot seeds. the less you have the better even if they are 10ft tall? what do you guys think? do you know of any size laws i dont?

Less is always better but just find a way to do it legally! Why risk all the red tape and your life/freedom when we are stepping so much closer to legalization etc?
