Hello all I need help giving my RSO a proper decarb.
I made 2 grams and I just want to know if 220f for 40 mins in a regular oven will work or should i go 210f for an hour?

How about 220f until it stops bubbling. You’ll notice the first set of bubbles you get big and small. Then just small then very tiny. I go until there is zero bubbling. There is no set time in my experience. Different types of extracts take different amounts of time.
I decarb on a hot plate with a regular beaker. I used to do 160c hot plate temp but I’ve recently changed to 200c because it’s faster and does the same thing if you pull it off when it is done bubbling you should see minimal degradation
I actually tested some bho sugar I decarbed on 200c hotplate temp just to make sure there wasn’t a lot of degradation and was happy with the results.

@anon56994712 is absolutely on point.
Decarb creates CO2 gas, so it’s really easy to see when it’s done…
Your heat source, the volume of your starting material, how much residual solvent you’ve got in there, and the age of your starting material all make a difference to how long decarb is going to take at any given temp…but regardless of that, when the CO2 stops, you know you’re done.

Ended up going 235°F for 30mins

why not decarb in a vac like a rotovap would it not help keep decomposition down?
was really wondering what everyone is doing for filtering/polishing rso from etoh extraction, keeping it crude? or degumming ? de waxing ? how fine of filtration?
I just use the stock 150 micron gasket that I got from bvv and the 150 micron gasket I got from m killa for my RSO filtration. I try to keep as much of the green as I possibly can. I stir the rso every 5 mins on the 5 mins when I do the 235°f in my kitchen oven. So far 235°f has been my sweet spot for decarbing RSO.
I’ve done the dewaxing until yellow at 4× 5 micron screen gaskets (not filter papers and disks, ik ik I gotta get them so I can hit 1um and .3um) I’ve done the double filtration method via grm tek and made rso with that crude but I still like it with all the greens still in it. I feel like you really get everything the plant has to offer by getting it as close to unfiltered as possible. I actually think a giant ass Mason Jar and straining with the lid is the absolute best filtration for RSO. 190um bubble bag wasn’t bag either cause you can squeeze out the biomass which is always fun.
It’s all preference tho.
Bucket Tek to 150um got great results too

Filtering is just to get waxes out because there is not much use for them in the body and makes a cleaner product? Is there much negative to the product if not filtered? I have seen more that because its a edible waxes are not to much of a concern. No one really wants to eat wax but is there a negative side effect to the product if not filtered, Lets says more for personal consumption and not for retail sale so there is no need for appeal and the best purity.

There is a couple factors taking place you should decide. What do you want out of the product? Do you just want to get high or would you like some medicinal effects? If you want some ailment than I would not suggest a full decarb. Keep some of that acid form in there and just decarb for 2/3rds of the time. I have seen full decarb with 235F for 45 minutes with no remaining bubbles. Cut that down to 25-30 minutes and keep some THC-A in there. If you want the full holy shit feeling than run it around 235F until it stops bubbling. I have also noticed a little stirring can help with the decarb.

A rotovap does use vacuum pressure to decrease substances’ boiling temperatures when recovering solvent. However, vacuum pressure does not influence the energy requirement needed for the decarboxylation reaction to occur, which must be met by adding heat. That is, vacuum will not allow you to effectively decarb at lower temperatures

silly me I was under the assumption less o2 while being heated would decrease desired compound decomposition
No, your point is perfectly correct, and I should have accounted for it!

love ya bud 
lol
The RSO veterans here may have determined by now that the threat of O2 doesn’t make it necessary enough to be necessary
Edit: at least for relatively quick decarbs. love!
I disagree, any volatile compound your after in chemistry common practice is vacuum and n2 purge. but that’s when exercising proper lab techniques. I guess it’s how much you care and how much of a nerd you are. its just so shitty of a concentrate nobody notices, do some testing but I assume it would be a waste of money because I am pretty sure it is a well known fact,
heat + oxygen = oxidation reduction. I just assume nobody cares that much lol
Are you certain the magic in RSO doesn’t reside in the oxidation products?
The “gets you high” doesn’t…and chances are it’s the activated and non-oxidized cannabinoids that are the predominant medicinal compounds, but the current state of our data acquisition leaves much to be desired.

Oh a lot of us are huge nerds and care a lot…but that doesn’t mean we’ll decarb under vacuum just because heat and o2 will be present. Consider what other compounds you might lose entirely because of the vacuum pressure. Then, consider how much o2 your system, which is constantly evolving heavier carbon dioxide gas, is actually likely to see…

I’ve thought the same thing. And then what about traces of etoh that are bound to be there? Won’t it just reflux?
I imagine N2 environment in a vessel would be best
The loss of terpenes during decarb is a concern for most people, but it’s not an easy problem to solve since anything that facilitates decarb degrades terpene quality. Maintaining low processing temperatures can help preserve some of the most volatile terpenes to a minor degree and decarbing with a containment that can trap them can also provide a small degree of salvation, but for the most part you have to accept the fact that when you choose to decarb you will have substantial terpene conversion and loss.
I agree with this statement
