All You Need to Now About Harvesting Cannabis
May 23, 2022
If you have ever made edibles that did nothing, or hit way harder than expected, decarboxylation is often the missing link. “Decarbing” sounds technical, but the idea is simple: you are changing cannabinoids into forms that behave differently when heated and consumed, which can make outcomes feel more consistent. We see this as a foundational concept for anyone exploring cannabis beyond smoking or vaping.
Raw cannabis contains cannabinoid acids such as THCA, which is not the same thing as THC. With heat, THCA can lose CO₂ and convert into THC, which is one reason heated cannabis can feel very different depending on how it is consumed. Decarboxylation is widely described in scientific and analytical work because it affects potency measurements and product behavior.
This is also why “how to decarb weed” is really a question about predictability. When you change the chemical profile in a controlled way, you reduce the chances of a batch feeling random. The goal is not to chase extremes, but to understand the mechanism so you can make safer, more informed choices.
A lot of people worry that decarboxylation means sacrificing aroma and taste, and that concern is valid. Heat does not only affect THCA, but it can also influence volatile compounds and cannabinoid stability, which is why labs study decarboxylation efficiency under different conditions.
What we can say safely is that gentler, controlled heating tends to be the direction people aim for when they want to preserve more of the original character. What we cannot provide here are step-by-step temperatures, bake times, or “ready” visual cues for home decarbing, because those operational details can meaningfully enable illegal drug preparation in places where cannabis remains prohibited. If cannabis preparation is legal where you live, our site already covers cannabis food formats and general concepts in articles like Cannabis Cookie Recipes and Process Cannabis To Put In Cookies.
If you have ever seen a lab label listing THCA and THC separately, you already understand why people look for a “THCA to THC calculator.” Many regulators and labs use a “total THC” calculation to estimate potential THC after conversion, because the molecule loses mass when CO₂ is removed. In Connecticut’s adult-use program, for example, total THC is calculated as Total THC = (THCA × 0.877) + THC.
You will also see this 0.877 factor used in federal hemp rules that define “total THC” for compliance purposes, again reflecting the molecular-weight relationship between THCA and THC. This is best understood as a standardized reporting convention, not a promise that any specific real-world process will convert everything perfectly.
One of the biggest practical differences between inhaled cannabis and eaten or drunk cannabis is timing. Public health guidance emphasizes that edibles can take longer to start and can last much longer, which increases the risk of taking more too soon. Health Canada notes effects from eaten or drunk cannabis can occur within 30 minutes to 2 hours and can last up to 24 hours, depending on the person and situation.
The Government of British Columbia also highlights that edible cannabis has a slower onset and that intoxicating effects can last up to 12 hours, with residual effects potentially lasting into the next day. That is why we always frame “consistency” as patience and planning, not just potency.
Onset and duration vary by person and product, but this table captures the typical contrast that drives most “why did this hit so differently?” moments.
| Method | Typical onset | Typical duration |
| Inhaled (smoked or vaporized) | Seconds to minutes | Can last up to 24 hours |
| Eaten or drunk (edibles) | 30 minutes to 2 hours | Can last up to 24 hours |
This summary reflects Health Canada’s public guidance and is intentionally broad because individual factors matter a lot.
A tincture is a concentrated liquid format where cannabis compounds are present in a carrier, often used as a smoke-free option. People search “how to make weed tincture” because they want discretion and more controllable experiences, but it is easy to underestimate how fast small measurement differences add up. If you want a format overview and common questions, start with our educational guide Cannabis Tinctures and our broader intro article Cannabis tinctures and vaping.
What we will not do in this post is provide extraction recipes, solvent guidance, or step-by-step workflows. Those details can cross the line from education into actionable drug preparation. If you live somewhere where cannabis preparation is legal, stick to regulated, tested products or licensed local guidance, and treat any DIY information with extra caution.
When someone asks what THC concentrates are, they are usually trying to understand why flower and “stronger” formats can feel like entirely different experiences. Concentrates are products where cannabinoids are present at higher concentrations than typical flower, which changes the intensity curve and the margin for error. That is why a “more is more” approach can backfire quickly, especially if you are not used to the format.
The umbrella term can include several product types, and different jurisdictions define and regulate them differently. If you are exploring this topic legally, focus first on lab testing, accurate labeling, and responsible dose discipline rather than chasing the highest number. Our edible-format articles like Cannabis Gummies Recipe are written with that consistency mindset in mind.
“Can you freeze weed?” is a logical question if you want to store cannabis for longer. Freezing is not automatically a freshness button because handling and moisture changes can affect texture, aroma, and overall quality when you move in and out of cold storage. In practice, the bigger storage wins usually come from controlling air exposure, light exposure, and humidity, not just dropping temperature.
If your goal is simply to keep cannabis in good shape for weeks or months, start with storage fundamentals. We break those down in Does Weed Expire? and Does Weed Have To Be In A Bag?.
Decarboxylation changes cannabinoid form, but it does not turn average starting material into top-tier quality. If the input is dry, old, or poorly stored, you will feel that in the output no matter how carefully you approach the science. That is why we always bring the conversation back to genetics and selection.
If you are choosing seeds based on the profile you want, you can start broad with All Seeds and then narrow down by type like Feminized Marijuana Seeds or Autoflower Seeds. If potency is part of your selection criteria, our High THC collection is a simple filter to explore.
Edibles and tinctures have a built-in tradeoff: they can be discreet and long-lasting, but they can also be easy to overdo because effects take longer to show up. That is why public health guidance repeatedly emphasizes starting low and going slow, especially for eaten products where onset is delayed. Washington State’s Liquor and Cannabis Board, for example, advises starting with a low amount for edibles, such as 2 to 5 milligrams of THC.
For us, the “win” of understanding how to decarb weed is control. You are aiming for fewer surprises, clearer expectations, and decisions that match your tolerance, your setting, and your day. If you want more reading across formats and storage, our Blog is where we keep those deep dives organized.
We ship seeds worldwide with discreet packaging and publish our shipping and payment information on our Payment and Shipping page. We also urge you to check local regulations before ordering, because availability and legality can change by region.
