co2 and air.

does anyone know if co2 is heavier than air? or when it does form in the fruiting chamber is it concetrated near the top? or bottom of the tub?

co2 is heavier than air, so it will go to the bottom of the chamber naturally.

If CO2 was heavier enough than air that it settled to the bottom, we'd all be dead from CO2 poisoning on the surface of the planet. CO2 mixes with the air. To get rid of it, you exchange the air in the terrarium. You can't simply drill a hole in the bottom and expect it to run out like water. CO2 is found high in the atmosphere, not just at the surface. It's the same in your terrarium. In a completely airtight container, the CO2 would sink to the bottom. Such is not the case with our growing containers. RR

CO2 is heavier than most of the other particles in the air. The reasoning "if co2 sank, we'd all die" doesn't apply. There are too many variables in the dynamics of the earth's atmosphere to make such a simple statement and generalize it to everything. Change in pressure gradients (aka wind) causes CO2 to circulate throughout the atmosphere, and eventually be dissolved into water bodies (this is why we don't die). When it comes to a terrarium, specifically a terrarium with no airflow or circulation, CO2 does sink, but not as a uniform layer that can "pour" out of holes if they were placed in the bottom. Basically, the highest concentration of CO2 exists at the bottom of a terrarium with little to no air flow/circulation, which is why it's best to place holes at the bottom.

Yes. The earth's atmosphere does not make a great analogy to the mechanics of gases in a terrarium, because weather invariably circulates the air. A terrarium can be utterly still, and allow CO2 to concentrate at the bottom. It doesn't take a lot of agitation to stir it up completely though.

hmm...this just came across my mind. when air is humidified along with the co2 is it still wise to put more holes on the bottom? because you might be losing on humidified fresh air as well?

what i did was i put a pvc co2 sucker in there it runs paralell to the side of the tank with holes cut to face at an angle to the ground and i hooked up a pc fan from radio shack i dont know how well it will work but the fan blows moderatly ss i think itll work good im using a huge glass aquarium btw decorated with uv paint it will be sexy
