I have been slowly drinking up a lot of Walmart brand soft drinks mostly just to get the empty 2 litre bottles for the incubator. Only got 6 in there now but from looking at them on the floor, and buying more tubs today, if I fill each shelf with 8 tubs I will have room for 2 water bottles on each side of the incubator shelves and 4 in the middle added to the 20 bottles that fit on the floor that would give me 44 of the 2 litre bottles in a 40 cu ft space. Is there a meaning for Overkill on temperature buffer bottles

Mind you. these are 15 qt tubs so that I should be able to fit any size clutch they throw into a single tub.
