    I've been searching for a long time for a chart about decarb time vs temp, where it covers the lower temps, like if using a sous vide. That has to be below water boiling temp so less than 212 F.

    There is a current chart that appears over and over, BUT I always was bummed that they didn't run the time
    access out further than an hour.

    This chart gives a range of temps/times in comparison to 230 F. For example, 212 F would take 2.o times as long to decarb VS 230F.

    It's not linear so sous vide temps would require much longer than at 230 F. No big deal as long as one
    has an accurate guide like this.

    I also want a guide for lower temps as I'm finding stovetop extraction with heavy cream works great. You get an infused heavy cream---great for hot chocolate or canna-creme brulee :)

    I've only done the cream method with ABV and one batch of golden honey reclaim from a bubbler.
    So I have not needed to decarb yet. In the future, when a normal supply is possible, then I'd love to try
    extracting from virgin cannabis---instead of the leftover ABV .

    So, how long would 230 be? I don't understand how the chart helps if I don't have a base time.

    Had the same question while reading this. And why 230F? Here water is boiling at 212F.

    230 F decarb time is generally accepted at 30-40 minutes.

    I think 230 F was used as a base as it is low enough to save terps etc yet high enough
    so as to decarb in a reasonable time.

    So simmering at 212 F (boiling water) in a double boiler (container with cannabis sitting in the water)
    would take 2X or 60-80 minutes.

    Temps below 212 F then require much longer times to decarb.

    Yeah. I've always done it in the oven at 240 F. For 40 minutes.

    While I don't doubt any charts, it's good to keep in mind decarbing happens over time, not all at once. And buds will naturally decarb over time on their own at room temperatures. You can eat a 6 month old bud and get high. Of course you can speed it up with heat.

    Over the years I tried a number of different decarbing methods, and they all worked. If your using low heat decarb longer, and vise versa.

    I'm skeptical of that. I have bud older than that that I still have to decarb.

    Decarbing is a more exact science today than ever. If you are decarbing high CBD pot for medical use, the decarb takes much longer. 240F for 40 minutes will only convert about 25% of the CBDa to CBD.

    And, since we are now aware of the incredible influence of the terps, you also have to consider that.

    I really love sous vide. It is about the only way to maintain the entire terpene profile for the "Full Entourage" effect. Decarbing just about any other way is sure to loose the low end terps like the Beta Caryophyllene and Alpha Pinene.

    Currently, I just have ABV/ not enough cannabis to do edibles from it so no decarb needed. In future, hopefully with bigger supply, I'll definitely try sous vide decarb.
    I'm sous vide-ing some post chops now so checked my unit----197 F is max temp. So, it would take about 4X the time of 230 F or about 120 - 160 minutes.

    Note that previously I used sous vide cooking to make some canna-creme brulee (made form super-golden hydratube reclaim where all vapor had been filtered thru hemp filter so no nasty ABV dust in the honey). The creme brulee was unbelievable and no grassy mj taste!!!

    For decarb, I sous vide at 190F for 90 minutes.

    For infusion, I use 170F - 180F for 4 hours. Sometimes more.

    For ABV, I often decarb but the last few times I skipped the decarb and left it in the infusion for 6 hours instead of 4.

    So nice. No smell, no muss, no fuss. I really like sous vide.

    Here is a nice cannabis sous vide site...

    I'd love to try virgin cannabis, infused in heavy cream at 170 F for 4 hours. That should keep max amount of the goodies and
    yield some awesome canna-cream which I find really nice for real-world, real-quick use. Canna-cream makes eazy-peazy hot chocolate AND all that butterfat helps ingest the make amount too.

    Note for infusing cannabis into oil or cream : I love T-Sacs !!!!!!!!! Hemp fiber tea filters, widely available on Amazon etc.
    I find them 10X easier than fucking around with cheesecloth straining of wet cannabis. Bag it before infusing and a firm/thorough squeeze after---need to experiment with putting it in French press too??

    I was skeptical as well until I tried it. I had misplaced a jar of Jack Herer for about a year, just about the time I read this. Actually I think I read it here, anyway, I tried it on a medium size bud and was amazed. I was much higher than if I vaped that same bud.

    you'll probably have better luck (and vastly better leverage) using a potato ricer, pop your hemp bag in there and squeeze like the dickens, should get most out.

    One way to get every last drop of oil is to use hot water. You put your herb/oil in a bowl and cover it in hot water, not boiling but hot, then put the bowl in a freezer. The oil will coagulate on the top as the water cools. Then just use a slotted spoon to collect it and pat it dry on a paper towel.

    Or, put your water mix in a sealed jar/container upside down while it cools. Then you can take the lid off and easily pour the water out. Easy peasy.

    I always used to water wash but since I discovered some terps are water soluble, I felt I was tossing the baby out with the bath water.

    Too bad, really. I always felt the water wash helped a lot on the taste. Still, I have tolerance issues and I need every terp working for me so I try to stick to anything that retains the Full Entourage.

    What I use now is a press that fits in my 1 ton arbor press. When I make butter/oil/whatever and I need to strain, I use cheesecloth (usually) and press it in my press. I have a pan setup that presses the load between 2 plates and the butter/oil drains into the pan. I never realized just how much I was throwing away with hand squeezing.

    However, there are arguments that say the harder you press, the more debris you add.

    So hard to know unless you try everything. LOL

    Not a great pic but another plate just like the bottom one goes on top of the load and then the pan collects. Crude, but it works...

    A lot of people, me included just make rosin and use that for medibles, canncaps and whatnot. That way most of the terpenes remain in the mix. For me it's just easier. But if you want to extract from used rosin pucks or abv then an oil (or alcohol) extraction is a good option.

    I never got into making edibles until I starting using rosin. It makes it so easy and potent.

    Is the image link for the chart broken or is it just my computer?
