Hey Demeter!
Here's a pic of my jugs. AHAHAHAHAHA! I've been waiting to use that.
And my ghetto carbon filter that I made with 90 mile an hour tape. There's a pic of it earlier in this thread too. Here's a link to the tut here on cdot for making one the right way

As far as what can wait...what do I know? I'm a noob. LOL! But odor control is definitely tops on the list. You want to keep your security as tight as you can. < that's the security guy.

CO2 is debatable. If you have good ventilation, you can get by without it. But it does increase yield, and your plants will tolerate higher temps with CO2 supplementation.

I like your fantasy. Especially the part about a strain that doesn't cause the munchies. I ate so much the other night after I smoked that I had wretched killer heartburn that woke me up out of a sound sleep and kept me up until 6am. It sucked out loud.
