really great tutorial
Home Made Carbon Dioxide Tutorial
Well after asking around and finding the simplest methods I came across a real easy way of making home made Co2 (thanks to skunkishybrid and m420) and i've illustrated it aswell, just thought i'd help a few of you out there who are new to this like myself.
When plants photosynthesise to make energy and grow they use Water (h20) and Carbon Dioxide (Co2) plus Light. They use half the amount of Carbon Dioxide to the amount of Water they use so this is alot of Carbon Dioxide if you think about the amount you water them, so giving them a boost of Carbon Dioxide during growth would be an advantage.
So here's my guide on how to make your own little amount of Carbon Dioxide to give your plants the boost they would love.
Obtain a bottle of any size, preferably plastic and fill it half way with water
Peirce the plastic lid using a hot pair of scissor or a pin
Make a funnel, either out of some card or paper or grab a funnel from your kitchen
Get some yeast, doesnt really matter what sort of yeast as long as it's active.. This only cost me £1.50 Sterling so probebly about $2-$3
Get some sugar or glucose, I've used sugar but glucose is cheaper, just get what you can get your hands on
Put about 1/5th of sugar to water in your bottle and the same for the yeast, 1/5th, it doesnt really matter so long as you have a decent enough amount
Ensure that your water has gone cloudy and remove your funnel and put the lid back on your bottle
I've used about this much yeast/suger mix at the bottom of my bottle
Cover the hole at the top of your bottle and shake well and continue to shake regularly for the next 48 hours to start off the reaction
Leave to stand for a second and pretty much straight the way bubbles should be on the top, this is the Co2 being given off
The bottles should be ideally placed at pot height, because from what I remember from chemistry Carbon Dioxide is lighter than air, because air contains so much nitrogen which is a heavy (Carbon = 12 atomic mass / Nitrogen = 14 atomic mass) so if place at pot height the Carbon Dioxide will rise into the plants leaves and stem where the photosynthesis occurs
this is a 3D image of how mine are setup
Hey presto, everytime you want to give your plants a little boost of Carbon Dioxide the cheap way! Just shake up the bottle and stand it next to your beloved plant. For greater Carbon Dioxide production, use a bigger bottle. If no more bubbles are produced after shaking your bottle then it means you need to add more sugar, if no more bubbles are produced after the sugar has been added then more yeast must be added to the solution.

really great tutorial
if anyone wants to help or give input on how i should grow my pot refer here
well i hope it helps some people
Looks good man.
I have a question about the application of this wonderful device. It's been a while since Chem 101 but is Co2 heavier than air or does it matter where the container is located? Should I just place it between my 4 pots or set it up on a shelve for the best, most efficient resuts?
Great Tutorial, thanks a bunch H2O!

Hey guys how long does a bottle of CO2 last?
