Yes, the air from the bathroom is fine. You just need cool air from outside your grow area. I would recommend you get some soil based nutes.. Fox Farms is a very popular nutrient line for soil.

In regards to the inline fan. A second inline fan would be beneficial if you set it up to exhaust the room and had your open end of your air cooled hood pulling air from the bathroom as well...

However if this is not possible then there is no need for a second high velocity fan really.
