How can I grow in an apartment in a legal state? Please help.

Michigan legalized growing up to 12 plants a year ago. Anyone can do it, however I live in an apartment, and they have stated they do not want weed here. I am eager to begin. I thought a good enough carbon filter would eliminate the smell. The best room I have to grow contains my water heater. Anytime maintenance has come in they always make a beeline straight for that room. Unfortunately, maintenance often enters my apartment without warning while I'm gone (and once while I was there). Any suggestions? Do I have any rights here? I assume they get to decide whether weed is allowed on the premises, but can I at least stop the maintenance staff from going in and out of my apartment whenever they feel like.

 

I'm not sure. I'd like to figure out what my rights are there because they've entered my apartment at least 5-6 times without my permission since I've moved in (one time they woke me up when they just walked in). It could be more because they don't always notify me they've been in there.

Something like an armoire could work if I could find one for cheap. I have a couple closets that would probably work for 2 plants. I might go that route unless you think a dresser like that would be better for the smell. I wanted to use my storage room because I could easily fit 6+ plants in there, but it contains my water heater, so that's a no-go. I don't need a lot. I'd be happy with 1-2 plants.
