I'd like to try making canabis oil using the so-call Rick Simpson RSO technique.

That means I will need to freeze my flower, freeze the grain alcohol then submerge the flower in the GA. Strain the spent flower then heat the remaining liquid in a rice cooker.

The final results will then be placed on a coffee cup warmer (a constant low heat) until the residual GA has evaporated.

Simple enough and since I do not have the background nor the equipment to do this any other way, worth a try for me, at least.

So my question is this. Since I will be saturating the flower with GA, is it necessary to dry and cure the flower or can I go straight from the harvest to making the oil. That is, will I lose any potency this way?

Thanks for any help and guidance.

I have never heard of anyone doing fresh frozen RSO, but I would like to see what the result would be.
The method you're suggesting is a fresh frozen QWET extraction followed by an unnecessarily warm removal of the solvent (depending on what you want to do with the final product).
Do you want to smoke or eat the final product? If you want to smoke it then try evaporating the alcohol off at room temperature in small batches in a glass pie plate instead of boiling it away hot, that should get you a tastier result.
RSO involves extracting at a higher temperature to get more of the green stuff with mysterious medical benefits into the oil, the point of keeping the material frozen is to avoid picking up that green stuff.

I agree with PDX that you should use time at room temperature to evaporate most of the solvent.

I put the material in a large jar and pour the GA / Everclear in, cap it, shake for 3 minutes (which is a long time to shake a damn jar), then strain it out. The tricky part is straining the material from the alcohol. You will need to use some progressively smaller strainers before the final coffee filter strain. If you dump it straight in a coffee filter without a finer prestrain, it will take an eternity to run through. I use a jelly bag first (you can use it to ring out the solvent absorbed by the cannabis), then a second wire strainer with very tiny holes, then it goes through the coffee filter. Use the unbleached filters that are round, as I've had trouble with the cone shaped ones.

Let us know how it goes. Good luck!

Water will make the efficiency of grain alcohol worse and extract more chlorophyll plus cause evap to be much longer.

My suggestion for RSO slow way
1: Fully Cure material- if you use oven do not go over 150F
2: Soak whole or ground material in the Alcohol for 2-5 days in dark
3: Filter with coffee filter -Check color if your not happy with clarity go to next step
4: Winterize extract 48hrs.
5: Evap out side With cheese cloth cover

My suggestion for RSO fast
1: Place material in stove pot
Cover with grain alcohol place on
20-45min on Low MedLow heat (WARNING FLAME DANGER) Do not go over 172.83F
2: Filter with coffee filter.
3: Evap with Heat out side on Low fan help

I would do this OUTSIDE....

This shit can blow you up and burn your house down

Using the rice cooker is a good idea...no spark no flame lots of ventilation

OUTSIDE! maybe on a screen porch with open windows and fans

Do Not burn your house down!

Rick says get the material "bone dry" and others have good de-carb info...

I would dry and cure and then get it a little extra dry through the de-carb for the grain alcohol wash

Good Luck and Stay Safe... Read alot about it...Take it Slow!

We have seen way too many tragic results already with BHO...Do Not Blow Yourself Up!

Keep It simple and just follow Ricks Method you will be fine

RSO is typically soxhleted unfrozen. What you are describing is closer to QWET.

RSO is also typically done with dry material, as wet material adds too much water.

Ok, so guess I'm mixing oranges with apples.

The end result is it load the oil into a vape pen cartridge made for these very thick oils. I use them now but have to buy the product at a medical dispensary. It's very expensive for only a tiny amount. Hoping to get around this and make my own.

My understanding is doing it with cold/frozen solvent and flower reduces the chance of getting chlorophyll in the final product. That "green" color you spoke of.

Understand about doing the rice cooker burn off with plenty of ventilation. Will do that in the garage near a window and running a fan. Thanks for the concern : )

The oil I buy new is golden in color. The RSO in the video is dark black. I understand the commercial product uses high-end CO2 extraction to obtain this purity. My chances of this are much less. Any suggestions with this added information will be appreciated.

BTW: I do have some flower that has been curing since mid October. I could use this batch and save what is coming to harvest in a week or so for my next try. I can only grow one plant at a time in my cabinet so not a lot to work with.

Just wanted to clarify.

RSO is ingested never smoked. DO NOT smoke RSO.

The oil in your vape pen is BHO or Distillate.

I know it gets confusing.

Put the rice cooker outside bro. It f'ing reeks. I use ISO as the solvent. A gallon of RSO cooks down in 15-20 mins.

Rick Simpson is not clear about how long it takes which I find stupid.
You will have black funk (RSO)

Good advice and fill in above. Sounds like you've read through Rick's instructions, they are explicit, and I suggest you take them as word.

It is difficult to get flow through ventilation in a garage, and they often have ignition sources such as water heaters. The high/low switching within the rice cooker is very likely an open contact thermal switch, an out and out ignition source. Rick is not being overly cautious when he states outdoors with a fan set to keep the vapors from entering the device.

So, extreme caution, and/or if you have the experience, open the rice cooker up, and seal off any sources of ignition.

QWET made from dried material and evaporated hot and relatively thick might be result in a product with the right consistency to work in pens, but it might not taste like primo material. If you evaporate away the solvent at a low temperature using a larger surface area for evaporation you'll end up with a product which tastes a lot better and is harder & less sticky, if its a thin enough film you'll get a shatter type result.



Just for the sake of starting an unnecessary but potentially amusing argument I would also like to add that I disagree with mushroombrew about not smoking RSO. I've smoked a lot of that stuff, it will get you plenty high and it has a unique flavor with is appealing to some aficionados, but is often rejected by people who haven't acquired the taste.
One time over 20 years ago I smoked so much RSO that I was certain that amount accumulated in my lungs would be enough to put me away as a large scale dealer had they decided to dissect me. I was stoned on that stuff for a long time, a couple years or so, smoked a bunch of it, mostly made with Everclear. No ill effects have reared their head yet.
