Wouldn't it be great if this actually does what it suppose to do? I think I will set-up a CO2 generator and try to adapt the petri dishes to allow some CO2 into them. I need to find some very small tubing, perhaps aquarium sized tubes and fittings could somehow be installed. Anyone have any ideas how to do this? The petri dishes are polycarbonate, so they will easily fracture. I think I will have to melt a hole for a fitting. Then connect it to a gang valve coming from the CO2 generator. Like an octopus rig.

Scot this sounds like an ideal situation to use a Small aquarium maybe that way the dishes could be set in it and you could pump the hole thing full of CO2 and you wouldn't have to fuss with cutting the dishes and with the hold thing sealed theirs not much risk for contamination how are you going to filter the Co2 id recommend A UV chamber and you will get the added benefit of some small amounts of O3 which is a nice Little anti bacterial gas if its in controlled amounts but i don't know what the optimum would be of if that would retard growth
