c02

[underboss22]

anyone here use the bottle with a reg for c02.. i have one but i dont have the "brain" for reading ppm.. anyone experiement with opening the valve manually or guessing the amount to let out..the grow store guy told me to get it hooked up to and electric timer and give it straight c02 for 15mins every hr.. my room is 8x8. what about spritzer water.. can i sub c02 this way untill i get the comp to calc ppm..
my room is sealed, no exhaust or air in, but i have a really high tech chiller system that converts c02 in the air..

I dont know anything about that but here is what I do:

Get any container, (I use a large vial), and pour in some water. Add sugar and bakers yeast. Presto, c02 being pumped into your room. Just set it by your plants.
