DIY: Home Made CO2 Guide

Here is a Tutorial for an easy CO2 setup.

Firstly u will need to get all the required items together..

You will need: - 2L Bottle.
- Release Valve (Twin Bubble Air-Lock) & Grommet. (Available anywhere 'Home-Brew' equipment is sold.)
- 1 Cup of Sugar.
- 1 Tablespoon of Yeast.
- & Some Glue.

Step 1 - Cut a hole in the lid for the Grommet & Release Valve.


Step 2 - Insert the Grommet.



Step 3 - Glue around the Grommet to help make it Air-Tight..

Step 4 - Insert the Release Valve.



Step 5 - Fill the 2L Bottle with 1L of Warm Water.



Step 6 - Add 1 Cup Of Sugar to the Water.



Step 7 - Add 1 Tablespoon of Yeast.

Step 8 - Fill the Release Valve with Warm Water.



Step 9 - Put the Lid on your Bottle & Give A Shake. (It's a good idea to have a second lid for the same bottle that has no holes in it, so you can use it whilst you shake the bottle, and then put the air-lock lid on, or else it can get messy.)




Step 10 - Time to Move your CO2 Dispenser to your Grow Room & Reap the Rewards



(Notice the Release Point of the CO2 is at least even with the Canopy.)

Things 2 Know About Adding Yeast & Sugar.

Too Much Yeast will cause the fermentation reaction to occur too quickly.

Too Much Sugar will break down the cells in the Yeast and not allow fermentation.

Both these things will affect negatively the release of the CO2.

You will know when you are out of CO2 in the Bottle because the Valve Release will stop bubbling.
You can add more sugar to the mixture when it stops bubbling, or simply empty it out & make up a new mixture.

Also it is a good idea to put the bottle of CO2 as level to your plants as you can get them as CO2 is heavier than Oxygen and will not benefit you or your plants if it is released at a lower level.

Enjoy

How often does this CO2 set up need to be changed roughly? Should I change it out daily? or does it need to be changed out more often?

Great Idea Ninja!! That piece is called a twin bubble air lock. It's used in releasing co2 from fermenting wine by home brewers. You can find them for around a $1 each at your local brew store, or at any brew supply online. +rep

ive tried making that style of CO2 generator but only had marginal results. kinda of a pain in the ass to keep going and the CO2 output isnt really worth the extra effort/expense. i really wish it worked better. such a great concept/idea. nice tutorial none the less!

Given the recipe for Co2 it should last roughly a week. But you will see if it stops bubbling sooner..
No1 is saying it beats the Gas canister method, but it is better than nothing if its all you can do.
Thanks Evil, i couldnt think of the name of it last night, but yes, i got it from the Brew shop.

sorry for the newb question but how much does a small co2 set up like this help? I'm only growing one plant and thought of doing the exact set up.
