oh and as for getting the seeds out (only works on shredded weed) get you a book, a place for the seeds to roll to and a card (doesn't matter how big as long as it's the size of a drivers liscense or bigger) put all the weed on the book and put the end of the book over where you want the seeds to roll angle to book so that the seeds will roll but the weed won't slide off, then just repeatedly pick up weed with the card and kind of sift it so that the weed drops...while doing this most of the seeds will hit the book and roll out while the weed stays on the book.....
