High olly, having allot of experience in this exact situation, I think I got a solution for you.

different strains need different screens. Sativa tricoms tend to be smaller than indica tricoms. if you have the 5 bag system don't mix all the bags together. such as your 190m screen is usually left by its self cause its mostly plant matter. its when you get down to 25, 70, 90, and 120 that the quality is the best. most say that when doing a indica strain the 120 bag is giving the best bubble. and when doing a sativa strain the 70-75 screen is giving the best bubble.with that said it takes a little experimentation with each strain to find that perfect screen that will give you the best bubble. being a big fan of the bubble too even over oil, I have bought oz's and ran them through the bags and then re-dried and smoked later but I got some clean bubble in the process. I don't do this often since I usually pay about 320 a oz or more so it is kind of a celebration thing.
Hope this helps bro.
MadSativa Reviewed by MadSativa on . Bubble hash wont bubble ?? Alrighty Ive been growing for many years now have have had many strains. Ive also made hash, gumby style to be exact. Now I have a bubblenator washer and bubble bags. My concern is my hash isnt bubbling when dry?? Ive done many runs with the washer using different strains and I only get pure bubble hash when I use a certain strain, why is that? Wouldnt all strains turn to bubble if processed right??
