@CurrDogg420 thank you, also one other question I have ongrok machine and for making the tincture I have about an ounce of my trimming’s from harvest and am wondering if I should just use one cup of everclear or perhaps use 2? I am just experimenting but I definitely want to make it good. If I reduce it down to RSO maybe I should use 2 cups to have more left at the end.

@jjress , if you’re intending to make FECO, the everclear is just a solvent. You won’t end up with more FECO, it will just take longer to evaporate the alcohol away. Use just the right amount to cover the plant matter, any more is a waste.

@retiredoldguy , I’m making it for the first time myself, so I’m just passing along what I’ve read.
Emily has a recipe for that too, which is the one I’m following, and according to her, yes basically.
You don’t need a soxhelet but it would be very cool. Its a laboratory device you can use for alcohol extractions. You can use it for chili oil too. It’s sort of like a still, and the alcohol is recycled by the system and can be completely recovered. In the homemade method, the alcohol is just wasted.

ok I have educated myself and I see RSO is typically made with Isopropyl and heated to reduce and Green Dragon is typically made with grain alcohol and air evaporate to reduce (can heat to reduce but can be dangerous). I always thought you should not consume Isopropyl but this is what RSO calls for…

I think sometimes the names are used interchangeably. They’re both Full Extract Cannabis Oil, and I think Rick Simpson invented the process.

@CurrDogg420 I didn’t know what FECO so I looked it up and found the same recipe, so based on the recipe being doubled I did it right and didn’t even know it….
I bought this machine for myself for Christmas, I was gonna buy the levo machine but this was more budget friendly at this time of year. I’ll reduce it down later this evening or tomorrow.

Actually I have some questions too on the topic of extraction.
One thing this FECO recipe didn’t tell me was how much to expect in yield. Probably it varies quite a bit depending on the quality of the product that went in. But, can anyone give me a ballpark estimate? I used 2oz.
Also, @MDBuds how does this product compare with the pressed rosin? They’re both extracting the same stuff more or less, right? Does that come out clearer because the alcohol is extracting more stuff? How does the yield compare?

I don’t have answers to either of those things but it seems like you get just a little concentrate according to what I have read, I then wonder how much concentrate gets used in let’s say a batch of gummies, I’m gonna try and find out. I don’t get medicated very often and don’t wanna knock myself out for a few days or so……that would be bad!! @CurrDogg420

@CurrDogg420 I think it comes down to your flower strength and amount, since no matter how much solvent you use you are always trying to reduce or rid it completely so in my simple mind that means what is left is truly a direct result of you bud potency and how much of it you used …but I am still learning about all these different techniques and end products…my last batch of Green Dragon I used about 10 grams of bud and let sit out until just an oily paste but still didn’t seem to do anything for me when taken in small doses, …but I am still learning and believe now I need to use at least an OZ to make it. Waiting for this auto crop to come in and I plan to use it for my next try at this.

@retiredoldguy it’s heat reduced alcohol tincture. I personally use non denatured alcohol not isopropyl.
@retiredoldguy did you make sure you decarbed it first? If you don’t decarb before making your rso or tincture it won’t work at all.
It doesn’t matter how much cannabis you use if you don’t decarb your end result won’t have any psychoactive or physiological effect aside from treating inflammation and nausea.
@CurrDogg420 If decarbed properly and extracted properly, your end result after reduction will be roughly right around your measured cannabinoid levels including thca, cbda, cbn, terpenes, etc…
So let’s say you use a cultivar with 30% total cannabinoids by weight and you use 1 gram for simplicity. 1 gram is 1000 mg. 1000 mg X .3 = 300 mg. So your end result would be 300 mg or .3 grams after extraction and reduction give or take depending on how much chlorophyll and fats and waxes were extracted as well and how much may have gotten burned off if heated or reduced too long.

@CurrDogg420 you will get a bigger yield with alcohol extraction because alcohol is a bi polar solvent and it strips everything out including chlorophyll.
Rosin you get slightly less yield because it doesn’t extract everything and very little chlorophyll is in it unless you press it fresh before dry and cure. The benefit to rosin is that you can smoke it and eat it and it’s a cleaner solventless extract.

@CurrDogg420 @jjress my alcohol extraction formula is helpful so you know how much alcohol to buy or measure out so you don’t waste anything. 1 liquid ounce per 2 grams of decarbed cannabis. If you fill the jar loosely with cannabis and leave room for aeration and agitation like you need you will use just enough alcohol to cover about 1 inch over the top of the buds.
I wish soxhlet extractors were more affordable to the average home grower though because they require far less alcohol and you can get your extract done in just a few hours vs waiting days.

My evap rig. 8 cup Pyrex measuring cup floating in a water bath in my mini crock pot. It’s working pretty fast. I thought about leaving overnight and felt safe enough about it but I think it would definitely be done before then.
When you’re making maple syrup you want a large surface area to start off with. I’ve got an evaporator which is basically a wood stove with a stainless steel pan on top for cooking the sap.
Another idea I had was to use these - they’re used as filters (these are the liners for the filters actually) for removing the sediment from your maple syrup before bottling. The 2oz batch size is a little much for a standard coffee filter. You can’t get the last bit of liquid squeezed out of the material. If you were working in large batches they could be handy.

@CurrDogg420 I’ll keep that in mind. The largest batch I can make at the moment is 80 Oz in an old pickle jar. I just strain it through a mesh screen when ready to get the plant material out and then I strain that through unbleached coffee filters into a large stainless steel bowl and use the double boiler evap method if I don’t cold evap.
If I cold evap I just strain from jar to jar as the process goes on. Cold evap usually takes me 3 days to a week.

@MDBuds thanks for all your information…I do decarb but just haven’t used enough bud in each batch to reach my level of needs

@jjress I make chocolates from tincture. I start with a tablespoon of dry cocoa in a little bowl, then drop the tincture on the cocoa. I make 24-piece bars, so I drop 24 doses onto the cocoa. I do 4 doses at a time, then let the alcohol evaporate before doing the next 4. This takes about a day for each 4 doses, 6 days total. By the end, the goodies are in the cocoa and the alcohol is all gone.
Then, I melt a chocolate bar of my choice in a double boiler with the cocoa, and put it in a silicon mold.
Works great. Good luck!

Lots of brownie recipes have chocolate liqueur in them so it may work perfectly

So, if I need infused oil for a tincture or a topical ointment or lotion, I start with an alcohol tincture, mix it with an equal amount of fractionated coconut oil (all the liquid components of coconut oil, with the solids removed), then heat on a double boiler until all the alcohol evaporates off. I put a liquid ounce of each in a tall 1 inch diameter jar (that capers come in). I was doing this yesterday and failed to mix it well. Plus I used more oil to make a weaker tincture. As it heated up, I noticed no bubbles were coming up. Apparently, the oil was floating on the alcohol and was too heavy for the bubbles to escape. So I tried to stir it with a chopstick. As soon as the chopstick broke through, the thing geysered and the alcohol caught on fire. Very exciting. Now I have a cannabis-infused stovetop.
@Bushdoc I turn my alcohol tincture into rso first before I infuse oils etc… just so I can make sure all the alcohol is evaporated out.
