Good tek
I use a 2" candle mold it already has the hole in it and I just tape or use rubber bands to hold cooffee filters over the effluent end.
I prefer to use Everclear to collect it. I've always wondered what it would be like to drink this mixture. I've only done about 7 or 8 fo these extractions but I use all the let overs from harvest and after I screen my trim I throw that in as well, almost like getting something for nothing.
