DIY C02 System Help

[Rxblade123]

Well after reading that if you want your plants to be in some good health and grow fast, you would need CO2 and all that stuff, I am now wanting to make a DIY CO2 System. This is me before reading the instructions some sites have. this is me after . Can anyone help tell me how to make one very cheaply, but one that still works well. I don't have much money so I won't be able to buy those little tanks of CO2 and that stuff so yea. Help is very much needed. TIA
Oh and if you people go on AIM and are willing to help me, IM at Rxblade123 to explain to me in a faster way, where it won't take a while before I get an answer lol. I'm not saying this board is slow though. It's lots of great help, but talking on AIM is way faster so yea. Lol.

well get a 2 L bottle first, which is like a regular soda bottle. Then you drill a hole on the cap big enough so u can insert an airline tube in. Just incase if there's any leaks, use silcone to seal it up. I made bubbles using 2 cups of sugar, 1/2 tsp of yeast and water filled up to 1 inch b4 where it curves. Pour the sugar in first then add some hot water, not so much, to dissolve the sugar. Then add cold water enough to make it warm. After that add your yeast and wait a couple of hours and bubbles should come out

Don't use a pop bottle. A juice bottle works much better as they have thicker sidewalls and a broader base so they are more stable. And you don't need the silicone. I have never used it. Drill the hole smaller than the tubing. I find that 11/64th works quite well with standard silicone airline tubing. Then cut the end of the tubing at a very sharp angle, thread the pointed end though the hole and then pull it though with pliers. I have used this method with many DIY bottles and in fact have used the same method on my bubble counters on my pressurized setups and on my DIY external reactors.

I have a juice bottle, but its like 1.68 litters. Oh and I dont have a drill. Can i heat up a long piece of metal and stick it through the top? I've done this before, but not for this reason.

This is the plan I plan on using - http://www.netpets.org/fish/reference/freshref/co2.html

yes, hot metal will work for making the hole, but in that case you might need a little tube of silicone...which you can buy at any local fish store...or probably even petco/wal-mart. melting a hole isn't as easy to make a perfectly round opening, compared to a drill.

1.68 liters isn't enough...go buy a gallon jug of ocean spray juice, drink it down, and use that bottle instead.
