If you were REALLY smart kids you'd start a grow op, don't tell a single person. Become millionaires.. And then you'd have all the private land you could hope for to smoke on.
Invest in a vape you can hide them pretty easy my best mate had one when he lived in student village and you could never smell a thing You can also buy lockable cases for vapes for like $50 off eBay etc making for secure storage
