yup, the bubblebags are definitely the way to go. just finished running my 4th harvest through them (over 4oz's of bubble hash out of this one!) and they're still like new and waiting for the next harvest...

i tried many of the pot oil (some wrongly call it hash) methods and all i got was green gunk, not much good for anything...or i usually just tossed the trim onto the compost pile. not any more...! those bubble bags have already paid for themselves ten times over! and it's high grade hash too...
