What Are THCA Diamonds?
THCA diamonds are crystalline structures of tetrahydrocannabinolic acid — the non-psychoactive precursor to THC. When done right, these crystals can test above 90% purity, making them one of the most potent concentrate products on the market. The process of growing them is called diamond mining, and it relies on controlled nucleation and crystal growth from a supersaturated cannabinoid solution.
What Is Jar Tech?
Jar tech is a passive THCa crystallization method that uses sealed mason jars, controlled heat (40-65C), and time (14-28 days) to separate cannabis extract into two layers: solid THCa crystals (diamonds) and liquid terpene-rich sauce. The process works by creating supersaturation: as the extract slowly purges residual solvent and the terpene fraction separates, THCa concentration exceeds its solubility limit in the remaining matrix, forcing nucleation and crystal growth. Starting material must contain at least 70% THCa for viable crystallization. Below that threshold, the solution never reaches supersaturation and no diamonds form.
The byproduct of diamond formation is terp sauce — a terpene-rich liquid that separates as THCA crystallizes out of solution. Together, diamonds and sauce represent one of the highest-value product combinations in cannabis extraction.
Jar tech is distinct from reactor crystallization (which uses jacketed vessels, added solvents, and precise cooling curves) and from BHO diamond mining (which uses controlled purge cycles in sealed columns). Jar tech is the simplest and most accessible of the three methods. No reactor, no added solvents, no specialized equipment beyond what most extraction labs already own.
Is Your Starting Material Ready for Jar Tech?
Jar tech fails or succeeds before you seal the jar. Most failures trace back to starting material that was never suitable for passive crystallization. Run these checks before committing 2-4 weeks of wait time to a batch that will never produce diamonds.
| Parameter | Target Range | How to Check | If Out of Range |
|---|---|---|---|
| THCa potency | 70%+ (75-85% ideal) | COA from extraction or in-house potency test | Below 70%: no supersaturation. Cold crash to -20C for 24h before jarring may help at 60-70%. Below 60%: not viable for jar tech. |
| Residual solvent (butane) | 5-8% by weight | Weigh before and after full purge of a test sample. The difference is your solvent content. | Below 3%: material solidifies, molecules cannot migrate. Above 10%: stays too dilute, crash nucleation when solvent finally flashes off. |
| Terpene content | 8-15% total terpenes | COA terpene panel or visual/olfactory assessment (strong aroma, pourable viscosity) | Below 5%: insufficient liquid phase for separation. The jar produces a solid mass instead of diamonds + sauce. Above 20%: dilutes THCa below supersaturation threshold. |
| Lipid/wax content | Minimal (dewaxed preferred) | If extract clouds when cooled to -20C, lipids are present | High lipids contaminate crystal surfaces, produce cloudy/waxy diamonds that test lower and look worse. Dewax or winterize before jarring. |
| Viscosity at room temp | Pourable, like warm honey | Tilt the collection vessel. Should flow. | Too thick (does not flow): too little solvent remaining. Too thin (water-like): too much solvent or too much terpene. Adjust recovery time. |
| Color | Light gold to amber | Visual | Dark brown/green: excess chlorophyll, plant material, or oxidation. CRC or re-extraction recommended. Dark material produces dark sauce and lower-clarity diamonds. |
The single biggest predictor of jar tech success is THCa percentage. At 80%+ THCa with 5-8% residual butane and a healthy terpene fraction, jar tech is nearly foolproof. At 70-75%, it works but requires tighter temperature control and more patience. Below 70%, you are fighting thermodynamics.
What You Will Need
- Glass mason jars — standard canning jars work perfectly for jar tech. Wide-mouth preferred for easier harvesting. Use new lids every batch (seals degrade with solvent exposure).
- Vacuum oven — for the final diamond purge and wax purge steps
- High-quality BHO — fresh extraction with controlled solvent recovery (5-8% residual butane remaining)
- Nucleation seed — approximately 1 gram of high-quality shatter or a pre-existing THCa diamond placed at the bottom of the jar (see the nucleation science section below for why both work but produce different crystal morphologies)
- Oven or warm storage area — capable of holding 100-120F (40-50C) consistently. A dedicated food dehydrator with removable trays works if you do not have oven space.
- IR thermometer or probe thermometer — verify actual jar temperature, not ambient oven temperature. Oven thermostats drift. The jar surface temp is what matters.
- Scale (0.01g resolution) — weigh jars before and after to track solvent loss over time
- Sharpie — for dating your jars (always label everything in the lab)
How to Make THCA Diamonds Using Jar Tech
Jar tech is the simplest diamond-growing method available to most operators. Here is the step-by-step process:
- Place your nucleation seed. Drop about a gram of high-quality shatter or a pre-existing THCa diamond into the bottom of a glass mason jar. Both work, but through different mechanisms that produce different results.
- Leave residual solvent. When you recover your butane extraction, leave roughly 5-8% residual solvent by weight in the material. The extract should be viscous and pourable, like warm honey. This residual butane keeps the cannabinoid solution fluid enough for THCa molecules to migrate and nucleate onto crystal growth sites. Too little solvent and the material solidifies before crystals can form. Too much (above 10%) and it stays too dilute to supersaturate.
- Fill the jar halfway. You want headroom in the jar. Do not fill it to the top — the residual butane needs space as it slowly off-gasses during the crystallization process.
- Loosely screw the lid on. Leave it slightly loose to allow pressure to equalize. Write the date on the jar with a Sharpie so you can track your timeline.
- Choose your environment:
- Oven method (faster): Place the jars in an oven set to 100-120 degrees Fahrenheit (40-50C). Do not use Celsius on a Fahrenheit oven — 100C would destroy your product. You will need to burp the jars frequently to release built-up pressure. Expect visible nucleation (small seed crystals) within 5-7 days. Full diamond growth takes 14-28 days.
- Cool dark place (slower): Store the jars in a cool, dark location for about one week. Same result, less babysitting.
- No vacuum needed. Unlike other purge steps, THCA diamond formation in jar tech does not require pulling a vacuum. The crystallization is driven by slow solvent evaporation and nucleation — not pressure differential.
Jar Tech Parameter Control: The Variables That Determine Crystal Size and Yield
Every jar tech variable interacts. Temperature controls nucleation rate. Solvent controls molecular mobility. THCa concentration controls supersaturation depth. Changing one changes the outcome even if everything else stays the same. This table maps the control variables to their practical effect.
| Variable | Low End | Effect at Low End | High End | Effect at High End | Sweet Spot |
|---|---|---|---|---|---|
| Temperature | Room temp (20-25C) | Very slow nucleation (4-6 weeks). Fewer, larger crystals. Terpene preservation maximized. | 65C+ | Rapid nucleation (3-5 days). Many small crystals (sugar). Terpene loss. Risk of decarboxylation above 70C. | 40-50C (oven phase), step to 55C for growth phase |
| Residual solvent | Below 3% | Material solidifies. No molecular mobility. No crystallization. | Above 10% | Solution too dilute. Stays fluid but never supersaturates until solvent flashes off, then crash nucleation (sugar). | 5-8% by weight |
| Starting THCa | Below 65% | No crystallization. Never reaches supersaturation. | 90%+ | Rapid crystallization. Large crystals possible but less sauce (low terpene fraction). | 75-85% THCa |
| Terpene fraction | Below 5% | Insufficient liquid phase. Produces solid mass, no sauce separation. | Above 20% | Dilutes THCa concentration. Slow or no crystallization. Lots of sauce, few diamonds. | 8-15% total terpenes |
| Jar fill level | Below 25% | Too much headspace. Solvent evaporates too fast. Crash nucleation. | Above 75% | Insufficient headspace. Pressure builds dangerously. Jar cracking risk. | 40-60% jar volume |
| Seed type | No seed | Slow, unpredictable nucleation. Random crystal distribution. May not nucleate at all at lower THCa concentrations. | Multiple seeds | Too many nucleation sites. Produces sugar instead of discrete diamonds. | 1 seed per jar (shatter for sugar/sauce, diamond for boulders) |
Why Shatter Works as a Nucleation Seed
Shatter is technically an amorphous solid — an organic glass without a perfectly ordered crystal lattice. Despite that, it acts as an aggressive nucleation catalyst through three distinct mechanisms.
1. Heterogeneous Surface Nucleation
A molecule does not need a perfect crystalline template to come out of solution. It needs a surface boundary. Dropping a solid chunk of shatter into liquid crude creates a massive solid-liquid phase boundary. The microscopic rough edges, fractures from breaking the piece, and surface imperfections all lower the Gibbs free energy barrier required for nucleation. THCa molecules in the surrounding solution grab onto the physical surface and begin clustering immediately.
2. Localized Supersaturation Spikes
Shatter is a concentrated mass of THCa and trapped terpenes. When it contacts the residual butane solvent at the bottom of the jar, the outer layer softens and begins to dissolve. This creates a microscopic zone right around the shatter that is flooded with an extremely high local concentration of THCa. This micro-environment crashes past the metastable zone and into the labile zone (extreme supersaturation), which forces spontaneous crash nucleation in that localized area.
3. Hidden Crystalline Embryos
While visually transparent and seemingly amorphous, stable shatter is rarely a perfect glass at the molecular level. It almost always contains sub-visual, microscopic crystalline clusters called crystal embryos. The moment the solvent softens the shatter matrix, these embryos are liberated into the surrounding solution, acting as thousands of tiny decentralized seeds.
Shatter Seed vs. Diamond Seed: Different Results
This distinction matters for what ends up in your jar.
Shatter seed: Because it triggers nucleation via surface boundaries and local saturation crashes, it produces rapid, widespread nucleation. The result is a burst of small-to-medium crystal clusters (often called sugar or cauliflower clusters) growing aggressively across the bottom of the jar. More nucleation sites means more crystals, but each one is smaller.
Pure diamond seed: A single crystalline THCa diamond suppresses widespread nucleation. Instead of triggering thousands of new starting points, it forces dissolved THCa to slowly copy its exact geometric lattice. The result is controlled single-crystal growth: a few massive, clear, faceted boulders rather than a floor of dense clusters. If your goal is large showcase diamonds, start with a diamond seed. If you want consistent sugar-and-sauce production, shatter works perfectly.
Jar Tech Failure Mode Diagnostics
When a jar does not produce the expected result, the failure always traces to one of these causes. Every problem in this table has been diagnosed in a real production environment.
| Symptom | Root Cause | Diagnostic Test | Fix |
|---|---|---|---|
| No crystals after 14 days | THCa below 70%, or solvent below 3% (material solidified) | Check COA potency. Tilt jar: if material does not flow, solvent is gone. | If solidified: this batch is done. Redissolve in butane and re-extract with proper solvent retention. If THCa is low: cold crash -20C for 24h, then re-jar at 40C. |
| Sugar instead of diamonds | Excessive nucleation sites (temp too high, solvent flash-off, jar moved) | Check oven temp with IR thermometer. Was jar disturbed? Was solvent above 10% at sealing? | Next batch: lower temp to 40-45C for first 7 days. Ensure 5-8% solvent. Do not move jars once sealed. Use diamond seed instead of shatter seed. |
| Cloudy or opaque crystals | Lipid contamination or trapped terpenes inside crystal lattice | Dissolve a crystal in warm pentane. If lipids precipitate when cooled, lipids are the cause. | Winterize or dewax starting material before jarring. For trapped terpenes: slow the growth phase (lower temp) so terpenes have time to exclude from the lattice. |
| Jar cracked or lid blew off | Pressure buildup from butane off-gassing. Lid too tight or not burped. | Always occurs in first 3-5 days when solvent off-gassing is highest. | Burp jars every 12 hours for the first 5 days. Leave lid loosely threaded, not sealed. Consider using jars rated for pressure (fermentation jars with airlock lids). |
| Sauce is dark and harsh | Starting material quality: chlorophyll, plant lipids, or oxidized cannabinoids | Compare starting material color to previous successful batches. Dark input = dark sauce. | CRC the starting material before jarring. Run through activated carbon + silica gel column. Or improve extraction parameters (colder solvent, less soak time). |
| Crystals forming on jar walls instead of bottom | Temperature gradient between jar wall (cooler, near glass) and center (warmer) | Measure oven uniformity. Glass walls are the coolest surface in the jar. | Normal in many setups. Wall crystals are still diamonds. To concentrate growth at the bottom: place seed at center-bottom and ensure oven has uniform airflow around the jar. |
| Crystals formed then redissolved | Temperature spike above 65-70C dissolved the crystals back into solution | Check oven temp log. Ovens with poor thermostats overshoot during recovery cycles. | Use a thermometer with min/max logging. If oven overshoots by more than 5C, use a lower setpoint or switch to a more precise heating source. |
| Very small crystals despite low temp and long time | Too many nucleation sites competing for THCa molecules | Did you use a shatter seed (multiple embryos) or were there micro-crystals already present? | Next batch: use a single diamond seed instead of shatter. Alternatively, use no seed and rely on spontaneous nucleation (slower but fewer sites). |
Diamond Grading: What Separates Showcase Diamonds from Production Sugar
Not all jar tech output is equal. The market prices diamonds based on visual quality, and the visual quality is a direct readout of how well you controlled the crystallization parameters.
- Grade A (showcase boulders): Single crystals 0.5g+, transparent to translucent, defined facets visible. These form from diamond-seeded jars at 40-50C with 75-85% THCa and slow growth over 21-28 days. Wholesale value is typically 2-3x production sugar. These test 95-99% THCa.
- Grade B (medium diamonds): Clusters of 0.1-0.5g crystals, mostly translucent with some opacity. Formed from shatter-seeded jars or slightly elevated temperatures. Clean separation from sauce. Test 90-96% THCa.
- Grade C (sugar/small crystal): Fine crystalline mass, opaque. Many nucleation sites produced many small crystals. Still a premium product when sold as “sugar and sauce” but lower per-gram value than large diamonds. Test 85-93% THCa.
- Fail (no separation): Homogeneous mass, no visible crystal-sauce separation. Either THCa was too low, solvent was wrong, or temperature was uncontrolled. This material can still be sold as BHO but has no diamond premium.
The terpene sauce byproduct has its own value. High-quality sauce tests at 30-60% terpenes with 20-40% residual cannabinoids. It is the most flavor-forward cannabis concentrate product on the market and commands premium pricing in states where terpene-rich products have consumer demand.
Harvesting, Purging, and Final Processing
Once crystal growth is complete (14-28 days depending on method), the jar contains two distinct phases: solid diamonds at the bottom and liquid sauce above them. Separation and purging are the final steps before the product is market-ready.
- Pour off the sauce. Carefully decant the liquid terpene sauce into a separate glass container. A gentle pour works. If diamonds are stuck to the jar walls, a warm water bath (40C) softens the sauce for easier separation.
- Rinse the diamonds (optional). For maximum clarity and purity, rinse the crystal mass with cold pentane. This dissolves any residual terpenes and minor cannabinoids clinging to crystal surfaces without dissolving the THCa crystals. Flash evaporate the pentane at room temperature. This step adds 2-5% purity to the final product.
- Purge the diamonds. Place diamonds in the vacuum oven at 90-100F (32-38C) and -29 inHg for 24-48 hours. Low temperature is critical: above 110F you risk partial decarboxylation of the THCa crystal surface. The goal is to remove residual butane and pentane without converting THCa to THC.
- Purge the sauce separately. Sauce contains more residual solvent than diamonds. Purge at 90-100F, -25 to -29 inHg, for 48-72 hours. Sauce is more viscous and retains solvent longer than solid crystals. Do not rush this step. Residual butane in sauce is a compliance failure and a consumer safety issue.
- Weigh and test. Weigh final diamonds and sauce separately. Calculate yield as percentage of starting material weight. Submit for potency, terpene panel, and residual solvent testing before packaging.
Scaling Jar Tech: From One Jar to Twenty
Jar tech scales linearly in a way that reactor crystallization does not. Each jar is an independent batch. Doubling your jar count doubles your output without changing the process. The challenges at scale are environmental consistency and batch tracking.
- Oven uniformity. A single jar in the center of an oven sits at 45C. Twenty jars packed into the same oven create hot spots and cold zones. The jars in the back run 5-8C hotter than the front. That difference produces sugar in the back row and good diamonds in the front. Solution: measure temperature at multiple positions. Leave 2-3 inches between jars for airflow. Rotate jars between rows at the midpoint (day 7-10) if temperature variation exceeds 3C.
- Batch tracking. Every jar needs a label: date, strain, starting weight, starting potency, seed type. When you are running 20 jars across 4 strains at different stages, you will lose track without documentation. A simple spreadsheet with jar ID, start date, parameters, and harvest date prevents cross-contamination and quality inconsistency.
- Burping at scale. Twenty jars need burping every 12 hours for the first 5 days. That is 200 burp events. Use fermentation jars with silicone airlock lids to eliminate manual burping entirely. The airlock releases pressure passively without allowing air ingress. This is the single biggest quality-of-life upgrade for scaled jar tech.
- Harvest scheduling. Stagger your jar starts by 3-5 days so you are not harvesting 20 jars simultaneously. Staggered starts mean staggered harvests, which smooths out your vacuum oven utilization and labor load.
Jar Tech vs. Reactor vs. Diamond Mining: When to Use Which
The three THCa crystallization methods serve different operations at different scales. Choosing the wrong method for your situation wastes time or money.
| Factor | Jar Tech | BHO Diamond Mining | Reactor Crystallization |
|---|---|---|---|
| Equipment cost | $50-200 (jars + oven) | $2,000-10,000 (closed-loop + columns) | $5,000-50,000 (jacketed reactor + chiller) |
| Skill required | Low. Patience is the main skill. | Medium. Solvent handling, pressure management. | High. Cooling curves, seeding, solvent selection. |
| Crystal size control | Moderate. Seed type and temp control size. | Moderate. Purge rate and temp control size. | High. Cooling curve + seeding = precise control. |
| Throughput | Low-medium. Limited by jar count and oven space. | Medium. Limited by column size. | High. 5-50L reactors process kilograms per cycle. |
| Cycle time | 14-28 days | 7-21 days | 24-72 hours |
| Best for | Small operators, artisan brands, anyone starting out | Mid-scale BHO labs with existing closed-loop systems | Commercial production, pharmaceutical-grade isolate |
| Purity ceiling | 90-97% THCa | 92-98% THCa | 95-99%+ THCa |
Start with jar tech. Learn what crystallization looks like, how nucleation behaves, what temperature control actually means for crystal growth. Then graduate to mining or reactor methods when your volume demands it. The fundamentals transfer directly.
How to Make Cannabis Wax From BHO
Wax is one of the most approachable concentrate textures to produce. The technique is straightforward: mechanical agitation at temperature.
- Whip the extract. Take your recovered BHO and whip it — like mixing a cake — for approximately 60 seconds. The mechanical agitation introduces air pockets that act as nucleation sites while breaking the amorphous glass structure of the shatter. THCa molecules reorganize from a disordered glass into a microcrystalline lattice, which is what changes the texture from translucent shatter to opaque wax.
- Watch the color change. This is your visual indicator. As you whip, the color will lighten dramatically. Grim describes it as adding egg to flour — the bonding changes the optical properties of the material. When you see that shift, you are done.
- The change is hard to miss. Side by side, whipped vs unwhipped material will look completely different. If you are not seeing a color change after 60 seconds, check your starting material quality and temperature.
Vacuum Oven Purge for Wax
Once your wax is whipped, it needs a proper solvent purge in the vacuum oven:
- Temperature: Set the oven to 115 degrees Fahrenheit
- Valve setup: Close the red port valve, open the vacuum valve
- Vacuum target: Pull to -28 to -30 inHg (inches of mercury)
- Duration: Standard 3-day purge — same as shatter
- Key difference from shatter: Do NOT flip the wax. Shatter gets flipped during purge; wax does not.
Pro tip for scheduling: If you are already running shatter in the oven, you can sync your wax purge to the same schedule. When you flip your shatter, bleed atmosphere into the wax tray and re-pull vacuum. You are doing everything you would do for shatter — just without the flip.
Compliance and Testing for Jar Tech Products
Diamonds and sauce are separate products with separate testing requirements. Both must pass state-mandated residual solvent testing before sale. The testing thresholds vary by state but butane limits are typically 5,000 ppm (California) to 800 ppm (Oregon) for finished concentrates.
The jar tech process concentrates residual butane into the sauce fraction (butane is more soluble in terpenes than in crystalline THCa). This means your sauce will test higher for residual solvents than your diamonds from the same jar. Purge the sauce longer. If your sauce fails residual solvent testing, extend the vacuum purge by 24-48 hours at the same parameters before retesting.
For potency testing: diamonds test as THCa (non-decarboxylated). The “total THC” on your COA will be lower than the THCa number because the conversion factor (0.877) accounts for CO2 loss during decarboxylation. A diamond testing at 95% THCa reports as 83.3% total THC on the label. This is not a quality issue. It is the standard conversion math.
Tips for Consistent Results
- Starting material quality matters. Diamonds and wax are only as good as the BHO you start with. Run clean material through a properly maintained closed-loop extraction system.
- Temperature precision is critical. 100-120 degrees Fahrenheit for diamonds (40-50C), 115 degrees for wax purge. Small deviations change your product texture and timeline. Calibrate your oven.
- Burp your jars. If using the oven method for diamonds, pressure builds up from residual butane off-gassing. Failing to burp risks cracking jars — or worse.
- Label everything. Date, strain, starting weight, method. Consistency requires documentation. This is how professional SOPs are built.
- Understand your purge. Residual solvents in the final product are a safety and compliance issue. A proper 3-day vacuum purge at the correct temperature and vacuum depth is non-negotiable for any product going to market. Review our residual solvent purging SOP for detailed purge parameters by solvent type.
- Track your results. Log every jar: strain, starting potency, solvent retention estimate, seed type, temperatures, timeline, final crystal grade, yield percentage. After 10 batches you will have enough data to predict your yield for any given input material.

Frequently Asked Questions
How long does jar tech take to produce diamonds?
Most jar tech setups produce visible crystals within 5-7 days, but full-sized diamonds require 14-28 days at 40-65C. The slow temperature ramp (0.5-1C per day increases in the first week, then holding steady) controls nucleation rate. Faster heating produces many small crystals (sugar texture). Slower, steady heat produces fewer, larger diamonds.
What happens if starting THCa is below 70%?
The extract never reaches supersaturation. THCa remains dissolved in the terpene and cannabinoid matrix without nucleating. You end up with a homogeneous sauce that never separates into diamonds and terp sauce. For material testing at 60-70% THCa, a cold crash to -20C for 24 hours before jarring can help initiate nucleation, but yields will be low and crystals small.
Why did my jar produce sugar instead of diamonds?
Sugar forms when nucleation happens too fast across too many sites simultaneously. The three most common causes: temperature too high (above 65C triggers rapid nucleation), residual solvent above 10% (excessive butane acts as a co-solvent that suppresses crystallization until it flash-evaporates, causing crash nucleation), or mechanical agitation (moving the jars disrupts the slow crystal growth process). The fix: lower temperature to 40-50C, ensure solvent purge to 5-8% before jarring, and do not move the jars once sealed.
Can you use jar tech with ethanol extract?
Not effectively. Jar tech relies on the differential solubility of THCa in a terpene-rich matrix. Ethanol extracts are typically winterized (terpenes stripped) and contain different impurity profiles than BHO. The terpene fraction that serves as the solvent system in jar tech is absent. For ethanol-extracted material, reactor crystallization with pentane or heptane is the appropriate method.
What is the ideal temperature for jar tech diamonds?
40-55C for the first 7 days (nucleation phase), then 55-65C for days 7-28 (growth phase). The two-phase approach works because lower temperatures favor fewer nucleation sites (bigger crystals), while slightly higher temperatures in the second phase increase molecular mobility and crystal growth rate. Never exceed 65C: above this point, terpene volatilization accelerates and nucleation rate spikes (producing sugar instead of diamonds). Some slow THCa decarboxylation occurs at extended hold times but is typically under 5% over a 28-day period. The real risk above 65C is losing terpene content and crystal quality, not significant potency conversion.
What yield should I expect from jar tech?
Starting material at 80% THCa typically yields 50-65% of its weight as solid diamonds and 25-35% as terpene sauce, with 5-15% lost to residual solvent evaporation and handling. Higher starting THCa (85%+) shifts the ratio toward more diamonds and less sauce. Lower starting THCa (70-75%) produces more sauce and fewer, smaller diamonds. Total recovered product (diamonds + sauce) should be 80-90% of starting weight if your purge parameters are dialed in.
Can I speed up jar tech?
Higher temperature accelerates nucleation and growth but produces smaller crystals and increases terpene loss. If speed matters more than crystal size, running at 55-60C produces visible results in 3-5 days with harvest at 10-14 days. The tradeoff is grade C sugar-and-sauce instead of grade A boulders. For production operations prioritizing throughput over showcase aesthetics, this is a valid approach. For maximum crystal size, there is no shortcut. Large diamonds require slow growth over 21-28 days.
How do I store finished diamonds and sauce?
Diamonds are stable at room temperature in UV-protected glass for 12+ months. THCa is crystalline and resists degradation in its solid form. Sauce is less stable: terpenes oxidize and evaporate over time. Store sauce in airtight glass containers at refrigerator temperature (2-8C), with minimal headspace, away from light. Sauce shelf life is 3-6 months refrigerated, 1-2 months at room temperature before noticeable terpene degradation.
