Truly excellent article! A great deal of high quality information here.

I do have some small issue with the CO2 section however, whatever my own feelings are on the cost effectiveness of CO2 supplementation at all for the hobbyist I don't think your yeast method, or for that matter any yeast method I've so far seen described, is workable. Yeast metabolising sugar as you describe in an unsealed container is performing aerobic respiration, the oxidisation of pertinent monosaccharides as shown by the formula: C6H12O6 + 6O2 → 6CO2 + 6H2O. This formula shows us that this process will generate approximately (~) 1.47 times us much CO2 as the mass of sugar involved. Assuming we are talking about some purely mythical yeast that will perfectly hydrolyse and oxidise every molecule of sucrose it comes into contact with, that you have added the appropriate yeast nutrients to your solution and that you can somehow keep the solution continuously oxygenated, the ~1.2kg sucrose in your jug will still only generate ~1.76kg of CO2 or ~1.47m3 worth when mixed with air at normal atmospheric pressure, ~52 cubic feet in old money. Even if you're only trying to boost the CO2 level by a few hundred parts per million, 1.47m3 over the several weeks that the magic yeast will take to produce it is not a lot given that you will need to ventilate your grow-room for temperature regulation and oxygen for both the plants and the yeast during that time.

Interesting also to note that this article is slightly different to the text used on the cannabis cultivation pages of the main wiki, was this a draft?
