Well.. If that's not working you should just buy the cheapest carbon filter + fan on amazon and be done with it IMO.

Although, even with a good filter and fan you have to have some negative pressure meaning that you have to suck out more air than you pull in. If you can't get negative pressure then the smell can leak out. If you have a tent and you get a real fan and filter you'll see the walls suck in when you close the tent and that means theirs negative pressure.

Here's some amazon links.

The one light will work and it's the one thing I wouldn't go cheap on. You could get the smaller size and still be ok. As for the carbon filter [this one on Amazon] (http://www.amazon.com/VenTech-VT-IF4-CF4-B-Controller/dp/B005GJ7TFE/ref=sr_1_2?ie=UTF8&qid=1449034018&sr=8-2&keywords=4inch+carbon+filter+fan+combo) comes with a speed controller which is great for reducing noise and controlling temps. You can mount the fan in the tent or out. It will sound like a fan is running 24/7. No different then a window fan. None of my house guests comment on it. Plus a nice filter and high power fan will be far less noticeable then weed stinking up the whole house.

As for number of plants I would do 3-4 on the first go so you get the hang of it and can make a mistake on one or have a male and not feel bad. The plants will grow as big as you want to allow. They will fill in all the space that is available. Also read up on trimming up all the lower growth once you flip light cycles so you get maximum large main nuggets. For example I had two sugar black rose in 5gal (19L) buckets and got about 200g dried. Now I'm doing one plant in a 10gal (38L) and it's much more hearty and bush like, explosive with growth, and yield should be similar. So if you want a lot of one strain go big or always do 2 so if you loose one you can just up pot real big and still expect a similar yield each time you harvest. Also 2 months is a tight time window it may be more like 3+ you can't rush nature :) going up to a larger pot as soon as you can allows the plant to get big right away. Keeping them in cups or starter pots longer then a few weeks it will grow more leaves when roots are stable, going up to larger pots right after that allows the roots to reach out more and gain large new growth. Only up pot about 3 times. You can always veg for as long as you want and flower will run another 6-8 weeks depending on the strain.

If you're going to grow in your closet (which sounds like the best option) you will want a carbon filter to prevent it from stinking up your place. You can buy carbon filter/fan combos on amazon that are very reasonably priced. This is a good option for a closet size grow.

80cfm is no where near enough to work as an exhaust only AND carbon scrubber in that way. just get a proper 4" fan and filter for that size, cheapies on amazon for ~$130 range with speed controller.

4" 190cfm inline duct fan and carbon filter combo $97

fan speed controller $21

If you can insulate it well, I bet 50*f outside could be dealt with. I'd be concerned about 'lights out' temps though.

Ipower is not really considered a spend more get more brand around here.

That said I have a cheap Ventec which came with a speed controller and it works fine. Moves some air, I keep it turned down most of the way. It is certainly not smell free, but it keeps it at a reasonable level for my stand alone house. Would not recommend it for an apartment. Not sure if they sell the same bundle in Canada.

For the price, this doesn't seem too bad.

I have this 4" (10cm) set and this 6" (15cm) set both going 24/7. From outside the rooms it sounds like air conditioning units going all the time. Not really audible from anywhere but the hallway in front of the doors.

My carbon scrubbers are placed like this. I feel like it helps pull hot air up and away from the plants.

My flower tent is 1m x 1m x 2m with a 600w hps which works out to 55w/ft^2 . My house is around 15-21c and I have to run an air conditioner in that room for most of the day to keep tent temps below 26c.

I have this combo in mind.
