In my dreams, I get a cleaner product with toluene or benzene vs. propanol, THF or acetone. Put an 8th through a mini coffee-grinder, but only chop it up enough that it would be good enough to roll in a joint; Grinding it to a fine powder will make it harder to filter later.. Add this to a coffee filter and tie it off with a paper clip; leave plenty of room within the coffee filter so the weed will have no problem mingling with the toluene. Squeeze this into a 500ml sep funnel, add near-boiling toluene to this, cap it off and let it sit for about a week, swirling it around every day. When the time came to open the stop-cock and filter, I let out a little at a time into a large test tube, boiled off the toluene, added more, boiled, etc.. Sounds tedious because it is, but the product is some sticky, messy shit, so I like to keep it in a small area instead of being spread all over a beaker. The residue can be dissolved in propanol, poured into a smaller test tube and boiled down again. That took forever, so I was thinking that next time I could suspend the "tea-bag" by a coat-hanger into a flask of boiling toluene.
