Joel was speaking at the club seminar and he actually has an CO2 measuring device. Out of my price range but he was speaking about very high levels of CO2 in his green houses generated by grass clippings and fresh manure. As for myself I used the yeast and sugar method like the pot growers on youtube. Lots of good growers in that world. The reason being is simply the sizes of my small greenhouses. It really only costs less $2 a week to make a sugar water generator. One of those things that you're not too sure if it helped or not but I did end up with two new PB's the first year I tried it.

Kathy insisted I plant one too. It's growing straight up at the moment with not many leaves yet. No idea what the hell it is by the picture on the label but one thing for sure...that gold laying egg goose is ours!

So are you taking a reading to know just how much CO2 is being released? After doing a quick Google search I found that the world wide CO2 average is around 400ppm. Desired amounts are in the 1000 to 1500 ppm range. Depending one what your growing and many other factors that will determine whether or not the added CO2 is beneficial. Just wondering is it cost effective and does it really give you that exponential growth you might be looking for?

Good info Phil. Will add that EC 118 is a powerful yeast found at most wine/brew shops and your aquarium tube dripping that 'gaseous gold' is well served taped to the back of an occilating fan. Homemade 'Trickle emiter' for those bigger plants;)

I was asked to put up a recipe for a CO2 generator that I used for a few years. Using a 4 L milk jug that's filled about 2/3 full of warm water, add 2 to 3 cups of sugar and 3 tbls. of yeast. You can also add a tbls. of baking soda. Shake well with a lid on and then take the lid off. CO2 will start to form the next day. Put this in your cloches but make sure you shake it twice a day. They last for about a week. Empty them out and restart again. Remember CO2 is heavier than air so open your cloches from on top. One design that I saw used aquarium air hoses siliconed into the jug top and the hoses then positioned over plant so the CO2 falls over the plant.
