Question Gatorade CO2 System?

I've been looking for a cheap DIY Co2 system for a while, and I found this. The person here uses a Gatorade bottle as the container. Do you think this could work well enough to grow ground cover plants, or plants in general? I'd also have nutrient rich substrate, Excel, and/or Liquid Fertilizers.

All the matierials are here:

Well, all DIY CO2 is fairly cheap. You could substitute 2L soda bottles for the gatorade. You'll probably want an extra bottle that can dual function as a bubble counter and yeast catcher.

But your question is whether it will be enough to grow ground cover. The answer is that it depends on the types of plants you're talking about and how big the tank is (and how many yeast reactors you'll use). As well as how you diffuse the CO2.

There are tons of vids on YouTube about creating DIY CO2 rigs. Check out a few of them for some ideas. But it appears that what you have will work.

I don't have too much experience, but I use the 2L soda bottles because they are specifically designed to hold pressure from within the bottle. Just makes me feel a bit better!

We use 2 Ocean Spray bottles that lead into a gatorade bottle. Works well! If you do the DIY Co2 I would recommend you go ahead and silicone around the openings to avoid leaks. We didn't the first time around and had to make another whole system because the other one was leaking.

Dependent on your tank size and your diffusion method and yeast mix, it can work wonders.

Like other above mentioned, using soda bottles designed to hold carbonated beverages are a good idea.

Wine/champagne yeast will also work much better but thats just my opinion.

No need for silicone, just drill the hole in your cap smaller than your tubing and use pliers to pull the tubing through, it will stay air tight. I've had one like this for 6 months now without problems.

Thank you everyone!

Helpful picture and link as well.
A matter of hours to get it started, says the person at the website.
Not bad, I might do the same technique they did.

i also used the 1gal ocean spray bottles with the white handels on them for 2 reasons:

1. wont fall over as easy as a soda bottle
2. handle is nice when its time to change to mix

I agree 100% on that part about soda bottles. Makes me feel safer too.

I don't understand why there are schematics in DIY co2 that use more than 1 bottle. Just use one gal ocean spray as one poster suggested, and pull a hose through with pliers. I've used that design for a year before getting lazy. Your yeast will ferment for a week then taper off, so pour some yeast water off and top off every weekend. Wine ferments to higher alcohol concentrations, less funky things growing and less likely to have stuck fermentation. Or you can spend around 40 bucks and do paintball co2

Yes, I think I'd want to keep it simple. What do we use the seperator for (example in tbonedeluxe 's picture)?

Also,
Do I get it? :
1. Do a yeast/sugar/water mixture and put it in a container, preferably made to withstand pressure but not required.
2. Put airline hose in container thru hole in lid. Silicone shut if necessary.
3. Put other end on a diffuser and place in tank.

Ok,
I did 1 cup white sugar and 1 cup brown (it might have been brown cane sugar).
I also added 1 tsp yeast and filled the container with some warm water.
One end of the airline tube is in the container, the other has an airstone attached and is in the tank.

It's been set up for about 20 minutes. I haven't seen anything happen yet. I plan on waiting for a day before doing anything further.

The separator has a couple purposes. One, it can be used as a bubble counter. And, two, it will trap any of the yeast solution that ends up in the airline, which can happen if the generator is dropped, knocked over, or shaken too violently.
