I wanted to share this with others just because it is a clean way to use the yeast method and it seems to def work!. If anyone out there has already made a page like this i appologize ahead of time.

To start here is a list of parts needed

-square or round 5 gallon bucket w/ lid
-Three 2 liter bottles w/ caps
-10-20 feet of 1/4 air tubing (depends on how far away you will keep it)
-Waterproof Sealing Glue (epoxy)
-6 cups of sugar
-1oz of yeast or 3 1/4 oz packets
-2x2 piece of foam
-2 1/4 T connectors

I started by painting the bucket black so that it would absorb heat to try and keep the sugar/yeast mixture at a warmer level. You need to keep the mixture at 70-80f or the yeast will die.

So once you have your bucket ready, mix your CO2!
mix two cups of sugar into a two liter that is halfway filled with water. shake the sugar up till it desolves. Once it has desolved all the way put atleast 1/4 oz of yeast in and shake vigoursly. Leave the top on until you are done. Repeat two more times i know its a bitch but it will pay off!

Next you should take the tops of the 2 liters and drill 1/4 inch holes in the top of each one. Then take a 6inch long piece of 1/4 tubing and push it through the hole so that only about a haf of an inch if through the other side. Then take your glue and seal the tubing to the 2liter top. Again repeat this two more times and let sit overnight to make sure it is sealed very well!

Once you have all three of the tops with the tubing read and dry, take a T connector and connect two of the lids. Then take another T connector and connect it to the other T connector so that all three are connected with one output. (as in pic)

Once you have the lids connected together and ready, take your yeast filled 2 liters and put them in your ucket. You will have to place them in carfully and make sure that they fit. Take your foam and place it around the 2 liters so that they are tight in the bucket so that when you shake and/or move the bucket system around after your done they wont tip over or move around. Dont put too much foam in to the point that it pushes in the 2 liter bottles. Once that is done put the three tops on your three co2 bottles!

i guess my question would have to be, since im not farmiliar with how to use c02, do you put one of the tubes directly into the soil, or just bust them into the tent, and have them blow co2 into the atmosphere of your growroom/?? please elaborate for a moron, lol.

And now for the final couple of steps, take the lid to the bucket and drill a 1/4 inch hole right in the middle of it and run a 1/4 air tube line through it and down to the 2 liters. Connect the tube to the available T connector which then connects all three 2 liters to the one Air line.

YAY, now you have a line of co2 that will last you two weeks in good conditions. I have run it into my res with GREAT results. I acctually made Two of them and ran them both into my res. You could tell by the next morning that the plants LOVED it. You could also just run the line right behind a fan and have it blow into the room and increase the ppm in the air. I think if you run it into your res you are getting the best of both worlds because it will come out of the res in bubbles and go into the air anyway. but it increase the co2 in the water which is very benificial. I hope this system will help someone who wants to use the Yeast co2 methos but doesnt want to have a stink bottle of soup sitting on the floor waiting to be spilled over. If anyone has any questions, comments or suggestions on how to improve the system please let me know. And to everyone who makes one, please post some picutres of you skills. good luck and happy growing!!!

CO2 should be around the leafs on the plant.
