get a 2 liter pop bottle...cut a hole in the top about the width of a pen...pour a tablespoon of dry active yeast...and a cup of sugar...then fill the bottle up with luke warm water, 3 inches from the top, shake until gross and cloudy, wait about 15-30 min and you will see bubbles floating to the top like beer. and there you have CO2....i have seen an immense improvement in growth. make sure to shake bottle 2-3 times a day, but its not necessary that often. just to stir up some more CO2...its smells like potatoes (some say) but i think it smells like an old beer case! good luck my friend

Carbonated is what we call it over here????

Thanks man thats handy to know will give that a try,do you have to change the water in it much,and how long would you use the
solution for before making up a fresh again????

two weeks at the latest. i got 3 packs of active dry yeast from the grocery store for 67 cents

Nice one,work in a kitchen so plenty of yeast and sugar at hand!!!Does the water not have to be luke warm to
set off the reaction between the yeast and sugar,or is the grow room warm enough??

i use luke warm to speed up the process then its goes to the rooms temp

i've seen co2 machines that are nothing more than a propane fueled pilot light.

i've also seen a lot of people mention that co2 isn't really required unless you have a large sized set up, high temps, or a sealed system. so depending on your operation you might just be wasting your time.

but on the other hand, i use the yeast bottle method in my flowering cab.

Nice one thanks!!!The room is sealed,it's one of those homebox tents,8 plants room is 1.8m x 2m x 1.8m,has a 600w hps too,so
do you reckon i need to bother,i'll use the bottle techniqe any way seems like the best option,Thanks!!!!

Indoor CO2 levels are typically close to double that out outside. So just a well ventilated room should suffice.

Thanks bubbles!!!!!I have a pretty powerfull intake fan and the
room has 3 vent flaps which are fully open and drawing in fresh air,
i am beginning to wonder if i need to bother with co2 at all??????
