Cost effective method for creating CO2?

Something I've wondered about before, being into growing plants and all, and knowing that plants grow at accelerated rates with higher levels of CO2, I've wondered about the best method for creating carbon dioxide for a small greenhouse or enclosure.

Anyone have any ideas?

I suppose I could look this up on the web, but Sciforums is more fun!

bacon soda and vinager worked great last time i checked.

Bacon soda!?!? Count me out!!!

Okay. Sodium bicarbonate vs. acetic acid... yes. I'm rusty on chemistry, but I would think that is a fairly easy way. If I was bold, I would try to work out that equation (I don't remember the word for it??)...

I wonder about the amount of gas produced by that?

 

Lime and vinegar?

Or just plain lime? As in Citrus aurantifolia?

i would say a fair amount, i mean i filled huge balloons before with a teaspoon of soda, and a few ml of acid. you get allot more then that for a few dollars at the pharmacy.

 

How did you do that? Tied a balloon to a valve on a bottle in which the reaction was taking place?

 

Yeah, I figured it wasn't the edible kind!

Well, okay, calcium carbonate is edible, I guess. If it's pure. Wait, isn't that the same as marble?

I know lime is used to prepare soil for certain plants... are you saying that there is a pronounced reaction in the soil? If so, what would that be?

 

Of course, you may have unwanted pH changes to deal with using that approach.

yup, just an experiment i did, back when i was in jr high.

thats excactly how i did it.

 

Of course, amending the soil with raw minerals may have unintended consequences depending on what you're trying to grow there.

Well, that's an option. A somewhat time consuming option. But an option nonetheless.

I guess that would be a good way to store the CO2. And of course, you could probably purchase some canisters of the gas for cheap.

 

This thread is making Al Gore angry. All this talk of the dreaded CO2! Oh, my!!

And in a positive light, to boot.

 

If you charcoal steaks etc, you could do it inside the greenhouse. Save your paper trash and do the same with it. etc. - All this is "free CO2."

 

Most grow ops use a standard commercial canister of CO2 vented into an enclosure with the cooling fans off, after lights out in 12/12, if they want to bump up yield a tad. The increase is marginal though, so only worth the effort for larger commercial grows.

Cabinet stuff is just fine with ambient CO2, there is more than enough in the atmosphere now, will be even more soon.

If you want more yield, higher grade genetics is a better first choice.

 

Well, I suppose the two would cancel each other out in fairly short time. I'm just wondering if all the added calcium and sulfur would be a hindrance to certain plants. I'm sure tomatoes would like the calcium, though.

Oooo! Don't get all "trippy" dude! It was just a joke I couldn't resist making.
