I see what your saying and agree with that if your going to grow in a tent or just a few lights.
Personally I wouldn't want the karma of possibly ruining someones investment by doing a larger grow in a rental. I also would not tell a landlord I did not trust 110% or who was not relying on me to pay the mortgage. Everyones situation is different, but there are definitely cool landlord that exist.
Hey Greenmango...
Yeah, this is going to be a small grow, one light in a fairly small tent. Nevertheless, I still would prefer to lower the stress level if I could by renting from a very cool landlord. I agree, I would need to trust them to a high degree. I'm a pretty good judge of character, and would need to get some very positive vibes before entering into a lease with somebody who knew about my love of gardening.
No situation is going to be perfect for me until I get a house with much more considerable privacy, but really, the potential pitfalls of having a landlord know about my grow are equaled by the pitfalls of the landlord not knowing (electric outage, there goes the odor control, landlord finds out, I'm out on my fucking ass in the street.)
