my kit 5 bag kit:
220 micron = work bag
160 micron = junk (good for cooking)
110 micron = ok, can be good
73 micron = full melt if you know how to spin
25 micron = with sativas I get bubble but not full melt

if you want full melt spin with a spoon for about 5 min (gentle)
NO drill, NO egg beater
do not be lazy!!!!!
let settle about 30 min.
73 micron = full melt

if you just want a bunch of good bubble hash use a drill, I never spun full melt with a drill.

buy the bags they are worth it.
Happy spinning :thumbsup:
