Curing lots ofsmall jars or large?

whats best big or small jars when curing i have both

What every you use only fill it about 2/3 full to allow moisture to works its way slowly out. If you use a large jar you should dump the buds out to allow air get to all buds. Quart jars seem to work well for me. I try to use the wide mouth jars (its easier to get the buds out), however, I do not buy new jars for this. Your not sealing it to cure so the peanut butter or mayonnaise jar work well.
Hope that helps, just open the offend at the begin .

glass or plastic? or it doesn't matter?

Glass is a much better option - it will not impart any smell/taste to your buds.
