Water cured RSO

[DabberDog]

48 hours. 2 water changes got rid of the brown water. Third and fourth changes were a bit murky. Final change and the water was fair clear and no longer smelled like tea.
The buds got cut into smaller bits and gently squeezed. They are sitting on a 25 micron screen on a cookie rack. Humidity the next 36 hours will be between 25% and 60% which will be great for drying. Rain comes tomorrow which bones that.
Visual inspection is good. There are still a lot of trichomes.

The vacuum pump I use is a Mighty vac hand pump type thing. Kind of like squeezing plier handles against a spring with one side connected to a a cylinder with a piston and some valves. I am on my fourth one now. Over time the piston develops drag, requiring more force to operate the pump. Eventually either the valves, seals, or the handle give out. I started with the cheap one, then bought the name brand thinking it would last longer, now I'm back to the cheap ones since they both crap out way to soon. I have used these for years working on cars and never had a problem. Idk if the difference is the amount of pumping required for the lab process or the presence of ethanol vapors. I was also wondering if the same problem was happening in larger electrically powered pumps.

Gee whiz! I don't know where the hell it went, but my water bud lost 1.5 grams. After less than 24 hours of drying, it's down to 8.5 grams. I'll leave it for a total of 24, but I don't think there's any more water. I thought this was going to take weeks.
A couple of the larger buds got cut to expedite the drying. After seeing what's happened overnight, cutting the buds was unnecessary.
Ethanol comes in a week.

Hi, Ck...
I was curious about your pump(s).
I have both Gast DOA and DAA diaphragm vacuum pumps that I bought used on eBay about 15 years ago when setting up my lab. I just looked them up and the specs say the components are highly resistant to all sorts of chemicals (should have first before posting my question). I imagine that they will perform well in alcohol vapor. New, they will pull 29.5, but mine are a bit worn.

How do I do this?
The point of this experiment is to see if water cured weed makes a better RSO than dried/cured weed. By better, all I mean is smell and taste. This is not about potency. But I will be paying attention to that.
What started out as 10 grams of dried weed turned into 8 grams of water cured.
When I do this wash, do I use 10 grams of dried like the water cured started out or 8 grams like the water cured became?

You are comparing the process, water cured vs air cured. You need to eliminate other variables, so gram per gram, use 10 grams for the non-water cured batch. What ever the water curing removed is a variable that you are testing for since smell and taste are the primary comparisons. Conversely if you eliminate part of the "stuff" that the water curing removed from the base line comparison, you are skewing your results. The theoretical is that the water curing did not remove any trich goodies. But theoretical vs practical yield will always be different.

Am I going to get in trouble for not taking notes,I think one of the cats ate my notebook, stupid cat

[DabberDog]

Trichomes did got knocked off.
The big variable: dryness. How dry was the bud before water curing and how dry is the un-water cured I'll compare to? Get me? You know Santa Ana Ckbrew, yeah? We had a few days after water curing so there's going to be a difference.
I think the answer is the water cured bud can compare to any RSO I've made. Doesn't matter the weight. I know what I'm thinking when I say that but it's hard to explain. Maybe percentage? Maybe ratio? If I wash 10 buds with 10 ethanols, and 1 bud with 1 ethanol the ratio is the same. What gets washed out will be the same strength/cleanliness based on bud content and how much ethanol it takes to wash it out.
Maybe someone else picks up on what I'm laying down and can help.
I got to wondering about making RSO with decarbed bud. I have to believe decarbed RSO is nastier than straight only because decarbed bud takes on a nasty flavor and smell. My opinion, anyway.

Hi, Dabber.
May I suggest you take 3 or 4 10 g bud samples from the same batch and run one sample through your usual RSO process. Sample, weigh and test this final result, writing it all down. This is your CONTROL batch.

Then run whatever new processes you want on the other 10 g samples, writing down the same measurements as the CONTROL batch. Compare these results with your CONTROL batch results.

Should be a simple comparison once you have all the collected measurements to review.

That's what I'm doing.  Everything is from the same two plants.  Started out with 10 grams for the water cured. Read on.

[DabberDog]

I think I figured out how to say it.
Strength and purity will depend on how much ethanol I use and how long I soak it. Bud quantity doesn't matter. Process matters.
If I use 1x of ethanol to wash 1y of bud, I should get the same strength and purity as if I use 10x of ethanol to wash 10y of bud.

[DabberDog]

10 minutes.
First thing to notice is the different colors the ethanol grabbed.
The biggest thing I notice that might not show up too well in the picture, is the clarity of the ethanol. I can see through the water cured, but not the straight. I think I already have my answer about a cleaner product.
Leaving this batch overnight. There is another quart jar.

[DabberDog]

Smells like black tea in the jar. Very nice. Even relaxing.
Tastes neutral. Vapor smell is a bit off. I don't remember coughing.
Consistency is pull-n-snap, if you know what that is. If not, Silly Putty: pulls slow and stretches or pulls fast and snaps.
It swelled up my face almost as soon as it got in my lungs. Had a moment where I was compelled to squeeze my eyes closed real tight so they didn't pop out my head. I am absolutely blasted after one dab.
Was it worth it? Yes, because I found water cured RSO is a cleaner product for dabbing than straight bud RSO. My little experiment added, maybe, 5 days to final product. I'm okay with that.
Will I do it again? There is a very good chance I will.
This is most of it. Getting pull-n-snap off a surface is a bitch. Even heated.
