Here are the steps from that site
I prefer to do the decarb on the extracted oil rather than on the bud. This way I'm raising the temp of the oil to 250F for about a half hour or until the decarb bubbles have slowed to very few. There can't be more than a few ppm of ISO left or when I make a bowl of oil I can't smell ISO and the human nose can smell it at 11ppm.
130g of fresh RSO after decarb. That was not cleaned up or winterized so not really potent but a rice grain sized blob can kick a heavy toker's ass.
Another time saving tip is instead of filtering the wash right away just pour it through a fine strainer into bottles or whatever then let it sit for 24 hours or more so all the fines settle to the bottom. Then decant it carefully into other bottles leaving the fine sludge behind. Then it will easily run through a coffee filter without the filter getting all coated with sludge and slowing everything down. I'm going to be doing gallons of this stuff as soon as we get some snow. Warmed right up here in northern Alberta and everything is brown. +8C and windy as hell today tho nice and sunny.
I do plan to clean up the oil I'll be making in the future. Good info in that 2nd link I posted earlier.
