Hi all
I'll have to say i'm no pro but have tryed this method of co2 production with 2 liter pop bottle with time i hope to better my production. Ratio's i use is
6 liter's water 4 cups white sugar 2-3 package's of brewers yeast 2 gram packges.

HOW I DO IT
boil water but remember to use a little more than your going to use . Let water cool " room temp is good " mix sugar and water together . Poor mix into 3 2 liter bottle's all with the same amount in each. Now the tricky part i find is the yeast i tryed the brewers yeast that come's in 2 gram package's i use 3/4 to 1 package per bottle> MIX WELL< that's it . mix well 3-6 times a day replace mix weekly with fresh mix " repeat from step 1 " .
i dont think this will help you in any way for larger grow's but i only have a 2-2-5 flower closet to produce for " i think it only help's if not venting all the time " to let co2 to build up for short pierod's of time . let me know what you guy's and gail's think .

hope this helps someone .

i filled a 1 galon milk jug withwate thetemp 110-115 water and 1 cup of sugar.i just used 1 pack of yeast

You completly underestimate yeast. Yeasts have different attenuation levels and percentages of alcohol they can survive in. Brewers yeasts live for over a week and usually use 75% of the sugar given to them up until the specific gravity of the solution lowers back down to near that of water. During the active life of a yeast culture it will pump a lot of CO2.

4-cups of sugar in 1 gallon jug, with two teaspoons of yeats will get about 14-days of C02...i doubt it is enought to worry about removing it during the dark cycle....besides you cant close it off, so your wasting it either way.....


Peace

i found that making a hole in the top of bottle then connecting fi tank tube to it and sealing, made me able to run the tube over the top of my ladies thus almost dripping co2 onto them, sweet
