I'm getting off the bho and trying rosin.  Well probably just both.  Invested in some pressing equipment. A press, some small bags,2"x3"&2"x4" my melting plates are only big enough for about an 8th of good bubble hash or dry sift per press.  I bought some dry sieves and some 100% mesh bubble bags, they are supposed to yield a better concentrate.  I have only done hand sifted trim heads to this point, no good material intil some practice. This is fun and will Definitely take a few runs to get good.
