CO2 Question : yeast and sugar

If anyone can help me out it would be great.

I started by yeast and sugar CO2 production today and here is what ive done:


1/2 Gallon Jug
3 Cups of Sugar
1/4 Gallon of water
Small spoonful of yeast
Hole with safety pin in cap

I was wondering if anyone knows how much yeast I should be putting in, I just guessed.

umm I put three tablespoons per gallon so put one and a half. I now use c02 in a pressurized tank it realy works well

thanks a bunch bro

yeast and sugar makes co2???????

never heard that before

Yeah man, it's so simple and so easy and its perfect for growing a single plant, which I am.

I must be doing something right because when I wen't to shake my mixure today and place it back down, the cap burst right off the entire thing, regardless of the hole I poked so I made another small hole.

Heres a recipe that should last a while:
Items Required:
* 10lb. white sugar
* 5 gallon clean bucket W/lid
* 4 1/2 gallons of water
* A piece of toast browned and hard
* A table spoon of dry active yeast (for baking bread)
First boil the water, (this will ensure clean water) remove from the heat and add the sugar. Stir until sugar dissolves. Let cool until water is room temperature (if you don't let it cool down it won't work).
After the sugar water has cooled, float the piece of toast on top of the water. Now, empty the tablespoon of yeast over the toast. After a few days, the yeast will take over the toast and start making bubbles (CO2) in the bucket. After a week, the amount of bubbling (CO2) will increase.
Keep the lid airtight on the bucket. CO2 travels up the dispersion tubing, and due to it being heavier than air, falls directly onto your plants. Timing your exhaust, is essential in maintaining an effective level of CO2.
Peace

a couple of tablespoons of active yeast
