You don't seal the bottle, but you need something like an airlock to ensure the yeast is respiring anaerobicly, i.e without oxygen. If the top is open, it will respire aerobicly and you will get no c02.

pretty cool thread... now the real ? if i had a room 9/9/9 ..`with intake and outtake air shut off during the light cycle12/12 would 2 two 1 gallon setups release enough c02 to be better that fresh out door air ...and if so what ppm would you think 2 1 gallon setups would produce in that space...i know 300ppm is coming in from outside getting exchanged ...but would 2 setups pump the co2 ppms say to 1000ppm for 2 weeks......less or more.
