I've read about CO2 and don't often forget what I read. So, some of what I read doesn't quite jive with some of the other things I've read.

First off I read that WORLD WIDE average CO2 in the air is really close to 300ppm. Yet I see people telling me they keep CO2 at around 210ppm. I'd have to assume the plants are eating it all up in that case!

I read that ALL plants completely STOP growing if CO2 drops below 200ppm. So 210ppm is really pushing the edge.

I read that plants thrive BEST at 1300ppm anything over that is a waste!

I read that Humans AND pets are typically effected (suffocate) at around 5000ppm.

CO2 weighs more then regular air. Thus without good circulation, a sealed room(or at least the venting is up high) it posses a risk of escape and could fill surrounding rooms and risk killing pets who naturally might be ON the floor.

Lastly I've read that current CO2 levels of around 300ppm are overall VERY low for our planet. We've had thousands upon thousand of years maybe millions where CO2 was 7-800ppm+. Yet our government is getting ready to sign a world treaty claiming CO2 is a hazardous waste product and thus will be taxed out the a$$ to the UN! How exactly can they tax us for over producing a naturally beneficial gas when technically it's at an ALL time multi million year low?:wtf:

Funny how growing mmj has suddanly brought government claims so much more INTO the light for me. If our government succeeds and we can get CO2 down below 200ppm we can have a world wide hunger issue. Because all our food will stop growing. Not to mention they are already showing our world temps are dropping NOT rising. It's now called climate CHANGE, Not global warming. I even found a few places showing growth in the ice caps over the last 3 years.

Have you ever seen the Penn and Teller video where they get MANY many people to sign a petition to ban Dyhydrogen monoxide(H2O) OR sodium phosphate(salt)? Kinda funny, because nearly everyone on the video signs this thing, banning water and salt without paying ANY real attention to what they are really signing.

However my point to all this is,.. If they start taxing the bejesus out of us for producing CO2 (which IS the case). What will become of the places selling CO2? Or the prices at such places? Seems to me a CO2 generator would be the smartest method. At least then you can buy Propane and convert it to CO2 without the government taxing you for "killing" our enviroment.
