bubble hash is going to depend on the quality of the trim or buds genral rule of thumb is 6 to 10 grams for every 100 grams of trim/bud just make shure u dnt use a blender with a cutting blade if ur going to do it with blender make shure its just regular beaters , i perfer not to use a blender/beater thing it rips the leaf up and leaves the water green ,,, and a wierd taste in the hash to me,, just when u put it into the bags make shure u use lots of ice layering it ice trim ice trim and stir for as long as u can and then let it sit and then stir again, then drain it out keep it cold as possible helps the resin heads break free from the ice,, aand i dnt recomend throwing any stems in or shade leaf the stems can rip the micron screen and the shade leaf the thrics will get caught up on them also so use good input material take ur time and enjoy hope this helps a little
