1. use more subtrate just still keep a 1/4 in verm seal. i still use 1 cc per hole x4
2. dont fill half way why?

if you pc em then you only need 45 mins but if you boil go with the water 3/4 a way up the jar for 1 solid hour at a slow bubbling roll. pc is way better. it seems i had to be way more sterile when making the jars up when i was boiling them to avoid contams. i just throw em together and pc now no problems. but i asked a question if it was possible to over cook b/c i just had to throw out some over cooked no growing cakes. i hope u understand me im baked early mornin

The reason I think a half full jar is ok is that it would have the same characteristsic of a half pint. That is, it could be strelized by boiling easily, and won't take forever to colonize. The substrate recipe would be the same.
