Bathroom ventilation?

Hey everyone, couldn't help but wonder if a bathroom exhaust fan could be used for a grow tent's intake ventilation. I was trying to plan out an attic grow using a grow tent and ventilation is of course a necessity. Did some looking around in the attic and spotted the bathroom exhaust fan, the ducting that led out of it, and was hit with an idea.

What if I connect the bathroom fan with the grow tent with some ducting to act as it's intake of 75 degree air, and then connect the original house ducting with an exhuast fan on another opening of the tent? So basically what I'd be doing is putting a grow tent in between the bathroom fan and the house ducting that would have carried the air out.


If anyone has tried this before, please let me know how it worked out! I'm curious and it seemed like a weird idea haha, thanks!

Well, the main issue is when you take a long, hot shower your fan will either be:

1. Not on, in which case your bathroom is too humid - bad in the long run as you know.
2. On, in which case your tent is being flooded with 100%RH air, which is also bad.

Doesn't seem like you can have one or the other. A wye connection may solve some of these difficulties provided you upgrade your outlet if it's only 4". That is, bathroom fan sucking and separate grow tent fan sucking attic air connect at a Y coupled to a 4x6" reducer and then to a 6" outlet. Not ideal but possibly worth a try.

^^^ Yeah what lowerarchy said, besides how bad would that suck if your grow tent smelled like the dump you just took? =P
