First Time Grower....LOCATION, LOCATION, LOCATION

100_4305.jpg100_4304.jpg100_4306.jpgFirst time grower and first time poster here. I have 2 locations, both closets, that seem ideal places to grow. I've done my research and the system I've decided to get is the Dual Spectrum Bubbleponics complete kit from Stealth Hydro.

1 closet is in my upstairs bathroom and the other is in my room. The closet in the bathroom already has a hole leading upstairs into the attic making a perfect setup for an exhaust fan, but the only setback is now that we're approaching fall there is an awful draft and its a little chilly in there. The closet in my room would be great too only thing is there is no way for me to setup an exhaust/intake system and I can't make any modifications whatsoever. I had an idea of leaving the door open and making a door out of thick black plastic with velcro on the sides for easy access. At the top of the door I was going to hang a dual exhaust/intake fan and another fan inside for air circulation. Any suggestions?

Another thing is is Im using decent bagweed seeds. I would love to purchase some feminized seeds online, but being that money is tight and no prior experience with growing I find it a little safer to grow with what I have than burn a hole in my pocket and I kill my plants after having spent good money on seeds. Any suggestions for some great seeds good for beginners?

I've attached pics of 100_4303.jpgthe 2 closets, the dual fan, and the hole leading into the attic along with a diagram of how my setup will look like...tell me what you think
