This is the method...I cannot locate the name of the bag or a location to purchase one. I tried several websites and head-shops. I need one asap. Thank you.

Just looks like a one gallon bubble bag to me.

That is a great method of hash extraction, gotta give it a go I think.

Its just called a hash bag. Go to kindseeds.com click on harvest at the top and itl take u there. Hope u got some money to dish out. Those things cost hundreds of bucks a bag and u will need afew of them to do the whole job.

Thanks to both.
