It works great and is like 10x's less likely to exploode. Flip sides' got the right idea that it feeds on sugar and reproduces itself with a waste product of Co2. I actually just add more sugar and a little yeast every 2 weeks although I suppose I should trade out a new bottle and solution. I am moving to a ventilation system which will be 3 2litre bottles that are connected using an elbow(PVC) and become the pressure driving Co2 and fresh air into the terrarium. I have a vent prob. if you read my truncata HELP topic. Well anyway It's a good natural means and the sphagnum loves the yeast.
