Total Newbie, any advice on setup?

OK, so this is my first attempt ever at growing. I have limit space in a corner of my bathroom behind the door. I set up an Aerogarden on the tomato setting, added a 5" bubble stone to the water, took a gallon jug and made a CO2 set up by punching a hole in the top and running a tube from it and taping it down the middle of the Aerogarden with tiny hole punched in the tubing and I have an 8" box fan to keep the air moving. I lined the walls and the back of the bathroom door with foil. I'm using the Aerogarden nutes at half strength because of threads that I've read here on the forums.

The I've got 4 plants so far, the plants are a week and a half old so far and are about 3" high.

Anything I've missed? Any other suggestions?

Thanks
Chaos

Ok, so my babies are 2 weeks old today from the day I dropped the seeds in the pods. Thought I'd post a few pics and get some opinions. Anything I can improve on? This is my first grow ever indoor or out so I'm open to suggestion.

Thanks,
Chaos

Looking good, it wont let me enlarge the pictures but from what I can see it looks like your off to a really good start. What strain are you growing?

Just seed from smoke I've bought in the past. I had no idea until I found this forum and started reading that there were so many types out there.

Later,
Chaos
