anyone know the co2 yeast recipe for a water bottle

I used (if i remember correctly)
about 15ml of brewers yeast and 600g of sugar.
pour into a 2 liter bottle with luke warm water, shake and watch it bubble. Have a pipe hanging over your plant from the bottle.
should last a couple of weeks though not sure how much extra CO2 you get.
See my setup bottle below -
