Oh, sweet summer child...
You've never dealt with a reef tank. 1000+ watts of metal halide lighting is extremely common, several hundred watts of circulation pumps, protein skimmers, heaters, etc. . Oh, and if you think you're having a lid on that sucker, chances are "no". That's all perfectly legal and can't get you evicted. I've personally worked on systems that have over 2000W of lights and at least half that in accessories. That's to say nothing of the hazards that go with marine organisms, palytoxin is no joke.
Now you want to talk about the safety of growing? My whole setup comes in at less than 700 watts. 520W in total lighting (on timers) and the rest is fans and exhaust. My lights use about 3.5 amps of total headroom on the breaker, the fans add maybe another amp. I could talk about startup surges for ballasts or constant current controllers, but considering your fridge or freezer has a much bigger surge for the compressor startup, let's not.
The humidity in the house is actually considerably less than when I ran my last two aquariums, same with the power bill. Don't be a moron, buy a dehumidifier if you need one.
Oh and if you want to talk about smell? I carbon filter; my anti-cannabis inlaws don't notice a damn thing. It's not hard or even particularly expensive to do this. This filter will do a 4 plant grow no problem and will last about a year to a year and a half of near-constant use: https://www.amazon.ca/VIVOSUN-Inline-Control-Australia-Charcoal/dp/B01MSEVQ3J/ref=sr_1_4?ie=UTF8&qid=1530731772&sr=8-4&keywords=vivosun+carbon+filter
If it doesnt work it doesnt work, find something cheap with a carbon filter, this here is 90$ cad
Just use one of these. This is the model I've used and there was virtually no smell outside the tent.
Don't waste your money on one. Just invest in a real filter you won't have to pass around
I think ducting is separate but basically this: https://www.amazon.com/dp/B01MSEVQ3J/ref=cm_sw_em_r_mt_dp_99V2Z0JP7NDKQT2D6M8A?_encoding=UTF8&psc=1

Here is what I am using.

I also bought some MDF board, and built a box for the fan to go into. It was a little louder than I wanted it to be, so now it's really quite. I will add a picture for you to check it out.
