Hey,
dude being your only 8 weeks in you got shit loads to learn, and sounds like your gonna learn the hard way, doggie goes out side, doggie is gonna bring in problems.
My mold issue started in my 1st DWC setup, combined with climate changes and my humidity when up after adding a 6" inline to bring in fresh air from outside so I made it a great place fo mold.
here is a thread about it and how I deal with it
I use a product called "Zero Tolerance" works great at controlling it.

I hope you make it without a pest problem, but they r so easy 2 get, being paranoid only is a joke until you wish you were, like say when my friends wound up n jail cuz they didn't listen to my paranoia.... Taking xtra steps helps make sure your gonna get your haul.
I didn't take the mold shit serious either, and now Im suffering from it.
You pretty much arent gonna cure mold, it winds up on all your great and everything so really clean up is a waste, we r moving n a few months so ill break and clean it all up then
and start with a brand new clean room next time.
Im gonna try this in a few days when a get a fehumidifier, gonna raise my grow room temp to 100+ for 1 hour.
90 degress stops mold growth and 100 kills it fast.
Read that in urban garden mag.
Im gonna shut down my fans the last 30 mins of lights on then when the HPS goes off Ill kick the heat on and the CFLs in the veg area will get it over 100 real fast.
