I would just set a micro grow box and get good/creative with lst training and have a small enough setup that can sit under something, or behind something or bottom corner of closet, ect..
I have a couple small spaces going and they are fairly low key and people think it's just a storage box or something. As long as I have notice to unplug things and hide the weird electric box aspects, I've had no problems. I've also never had someone go through all my belongings but if I did I'd probably get pretty pissed. Renting sucks.
I've had a couple strains that smelled too strong and you could smell them flowering as soon as you walked in, that wasn't very fun times.
Yea this was one way I was thinking.. my last grow was in a 600x600x900 tent and scrogged a single dwc did really really well off it!
