So, do you heat the jar or lid?i read about it in my high times grow guide. you heat the jars at about 150 degrees (not too high) so when they cool, the air creates a suction. like when you open a jar and you hear that 'pop'. you can store for years that way if they are cured properly. if you just screw a lid on a jar, it's not vaccumed sealed for freshness.
