I recently helped a family member of mine extract one of his first successful grows and thought I’d share the process and pics with my fellow cannabis extractors.

My cousin has been open blasting to make his extractions but last month I finally convinced him to invest in a closed loop system like mine. He went with a Terpp Extractor and I set it up for him outside : http://i.imgur.com/J8ii0ln.jpg

We used a mixture of propane and n-butane, I like using a mix with some propane because it extracts better than pure n-butane in my experience.

First step: Get all the nugs off the plants. Here’s one of the plants: http://i.imgur.com/oLwtWBP.jpg

Second step: FREEZE the nugs, fresh off the plant. We used dry ice in a cooler for about 30 hours. Pic of the nugs : http://i.imgur.com/OWOSaX4.jpg

Third step: Pack column nice and tight with frozen buds and run the solvent through the system. Collect the oil when it’s ready (I like to gently scrape onto pyrex dish or PTFE sheets, try not to agitate it too much).

Fourth step: Put it on the heat. My friend uses this vacuum set up. It gets the job done. I like my vac oven because it provides heat in all directions, but I used a set up similar to this for a very long time, it’s a great budget way to purge your extracts.

This is the heating pad we use underneath the chamber. It stays at a fairly consistent temperature, we kept the heat at 95 degrees, bumping it up to 100 near the end.

Fifth step: Once the oil is melty and in a nice patty, put it at full vac and keep it on the heat for however long it needs. This is tricky, some strains are done in 24-30 hours. Some strains require a full 48 hours. I’ve gone even longer when there is a lot of moisture from fresh frozen or live resin runs. The reason it takes so long is because we are using very low temp’s to preserve the flavor and color of the oil.

At around 10 hours in I will “flip” the patty of oil, like a pancake. I’ll put a ptfe sheet on the top of the oil, flip it upside down, and continue purging on low heat at full vac, Flipping the patty will get the solvent out faster and more effectively.

Keep doing it every 10 hours or so until your oil is done.

This Durban Poison was in the chamber for 50 hours.

62 grams of fresh frozen nugs turned into 14 grams of fresh frozen oil.

As you can see, it stayed very sappy. Not very stable, but this happens a lot when dealing with fresh frozen or live resin oil. Maybe due to moisture or other factors like strain.

The taste is incredible, I’m a big big fan of Durban Poison. Very distinct flavor, super fruity and sweet. The effects are an amazing clear headed, sativa high. Good for day time smoking.

If you have any questions feel free to ask! I’ve helped a bunch of people here find and set up closed loop systems and with purging advice, I don’t mind PM’s at all :)
