WOW Super useful man I have been wondering about this for so long. Adding lots of soda to my space sounded messy and like it wouldnt work +Rep, Again Thanks
Ok, Well use your head.. and make a bigger scale? Nice Find.. +rep http://forum.grasscity.com/advanced-growing-techniques/ I would put this type of Thread in that section .
Yeah I just doubled everything up with a 2 liter and 1 fat straw, 4 cups water 2 cups sugar and a Tablespoon of yeast. I made 2 of these and its sufficient.
Not enough for anything bigger than a pc/small box grow. Go out and buy a CO2 tank+regulator and the CO2 PPM detector....trust me it'l work much much better than the yeast sugar method.
