Drying and Curing Marijuana Buds: Why Do It?

How Cannabis is Dried and Cured — Why It Matters for Quality, Potency and Flavour | Lower Mainland BC

When you order premium AAAA+ cannabis from Freshly Rated Cannabis and notice how much better it smells, tastes, and smokes compared to lower quality flower — a large part of that difference comes down to one thing: how well the cannabis was dried and cured after harvest.

Drying and curing are the final steps in cannabis production — and arguably the most important ones. Even perfectly grown, genetically exceptional cannabis can be ruined by poor post-harvest handling. Conversely, a well-executed dry and cure can elevate good cannabis to outstanding quality.

In this guide we’ll break down exactly what drying and curing are, why they matter so much for the cannabis you consume, and how Freshly Rated Cannabis ensures every product on our menu has been properly processed before it reaches your door in Surrey, Vancouver, Burnaby, Langley or anywhere across the Lower Mainland and Fraser Valley.

What Happens When Cannabis is Harvested?

At harvest, a cannabis plant contains a significant amount of moisture — typically 75-80% water content by weight. The freshly harvested flowers are pliable, dense with moisture, and contain chlorophyll and other compounds that produce a harsh, grassy taste if smoked without further processing.

The raw flowers also contain THC-A (tetrahydrocannabinolic acid) rather than active THC. THC-A is non-psychoactive — it only converts to psychoactive THC when heated through smoking, vaping, or other decarboxylation.

Before cannabis can be consumed, it needs to go through two distinct processes:

Drying — Reducing the moisture content of the buds to a level that prevents mould while preserving quality.

Curing — A controlled, extended storage process that completes the transformation of the flower into the premium product that consumers experience.

Both steps are essential. Neither can be skipped without significantly compromising the final product.

The Drying Process — Getting it Right

Why Drying Speed Matters

The speed of drying has a dramatic impact on final quality. Quick-dried cannabis — rushed to market in days — will smell like grass or hay, burn harshly, and deliver a flat, unpleasant smoking experience.

This is because slow drying allows aerobic bacteria and natural enzymes to break down chlorophyll, sugars, and other compounds that contribute to harshness. Fast drying preserves these compounds in the bud — and you taste them when you smoke.

Quality producers take their time with drying. There are no shortcuts.

Optimal Drying Conditions

Professional cannabis drying requires carefully controlled environmental conditions:

Temperature: 15.5°C to 21°C (60-70°F) — Cool temperatures slow the drying process appropriately and prevent rapid evaporation that can cause uneven drying or terpene loss.

Humidity: 45-55% relative humidity — High enough to prevent the exterior of buds from drying faster than the interior, but low enough to prevent mould growth.

Airflow: Gentle, consistent air circulation — Fans in the drying room help prevent stagnant air pockets where mould can develop. Airflow should be indirect — blowing air across the room rather than directly onto the buds.

Darkness: Light degrades cannabinoids, particularly THC. Drying rooms should be as dark as possible.

Maintaining these conditions requires a dedicated drying space with a dehumidifier, air conditioner, and circulation fans — a significant investment that separates serious cannabis producers from those cutting corners.

The Cut and Hang Method

The most common professional drying method involves cutting branches of 12-16 inches from the cannabis plant, removing large fan leaves, and hanging branches upside down from wire or string in the drying room.

Some producers opt to cut the entire plant and hang it whole, while others cut individual buds. Each approach has trade-offs:

Whole plant or large branches — Faster initial harvest, but longer drying time and requires thorough trimming after drying.

Individual bud cutting — More labour-intensive initially but faster, more controlled drying.

Regardless of the cutting method, quality producers monitor their drying rooms continuously, checking temperature and humidity daily and adjusting conditions as needed.

How to Know When Buds Are Ready

Cannabis is typically dry enough to move to the curing stage after 5-15 days, depending on:

• The density and size of the buds
• The environmental conditions of the drying room
• The strain — some strains are naturally denser and take longer

The classic test: take a small branch and attempt to bend it. If the branch snaps cleanly — it’s ready for curing. If it bends without breaking — more drying time is needed. The exterior of properly dried buds should feel slightly crunchy to the touch.

The Curing Process — Where Quality is Made or Lost

If drying is important, curing is transformative. This is the step that separates a good final product from a truly exceptional one.

What is Cannabis Curing?

Curing is the process of storing dried cannabis in sealed containers under controlled conditions for an extended period — typically 2-8 weeks, though some premium products benefit from curing for up to 6 months.

During curing, complex biochemical processes continue inside the bud even after harvest. Understanding these processes explains why curing is so essential.

The Science of Curing

Chlorophyll breakdown — Fresh cannabis contains significant chlorophyll, the green pigment responsible for photosynthesis. Chlorophyll produces a harsh, grassy smoke when burned. During proper curing, aerobic bacteria and enzymes break down chlorophyll, improving smoothness and flavour dramatically.

Sugar and starch conversion — Cannabis buds contain sugars and starches that, when smoked, produce harshness and can contribute to headaches. The curing process allows these compounds to be broken down and converted, improving the quality of the smoke significantly.

Moisture redistribution — During curing, moisture from the interior of the bud migrates to the exterior, creating a more even moisture distribution throughout the flower. This is why properly cured cannabis feels slightly sticky and pliable rather than brittle.

Terpene preservation — Terpenes are the aromatic compounds responsible for the distinctive smell and flavour of different cannabis strains. Slow, controlled curing preserves terpenes far more effectively than quick-drying methods. This is why properly cured cannabis has complex, strain-specific aromas.

Continued biosynthesis — Even after harvest, cannabis plants continue biosynthetic processes. During curing, non-psychoactive cannabinoids can continue converting to THC-A, and the overall cannabinoid profile stabilizes. Proper curing conditions allow this process to complete naturally, potentially increasing the final potency of the flower.

Curing Containers

After drying, cannabis is typically transferred to airtight containers for curing. The most popular choice among premium producers is wide-mouth glass mason jars. Glass is inert — it doesn’t affect the smell or flavour of the cannabis — and creates an excellent airtight seal.

What NOT to use for curing:

• Plastic bags — allow oxygen permeation and may impart plastic taste to cannabis
• Plastic containers — similar issues plus potential chemical interactions with terpenes
• Metal containers — can affect flavour over extended curing periods

Buds should be packed loosely in containers — never compressed. Crushing buds during storage damages trichomes and degrades quality.

The Burping Process

For the first week of curing, properly cured cannabis requires “burping” — briefly opening the containers multiple times per day to allow moisture and gases to escape and fresh oxygen to enter.

This burping process prevents the buildup of anaerobic conditions inside the container. If you detect an ammonia smell when opening your curing containers, this is a warning sign — anaerobic bacteria are consuming your cannabis. Correct this immediately by increasing the frequency of burping or slightly extending drying time before resealing.

After the first week, burping frequency can be reduced to once daily, then once every few days as the cure progresses.

Optimal Curing Conditions

Temperature: 15.5-21°C (60-70°F)

Humidity inside containers: 60-65% relative humidity

If humidity inside containers drops below 55%, the cannabis is too dry. Rehydrating with a commercial humidity pack (like Boveda 62%) or even a small piece of citrus peel placed briefly in the container can restore moisture.

If humidity inside containers rises above 70%, the containers need to be burped for an extended period (12-24 hours) to allow excess moisture to escape before resealing.

Darkness: Store curing containers in a dark cupboard or drawer. Light exposure degrades cannabinoids during curing just as it does during drying.

How Long Should Cannabis Cure?

This is where premium producers distinguish themselves from producers focused purely on speed to market:

Minimum cure (2-3 weeks) — Better than no cure at all but the final product will still have room for improvement in flavour and smoothness.

Standard cure (4-8 weeks) — The sweet spot for most strains. Chlorophyll breakdown is largely complete, terpenes are well preserved, and the smoke is noticeably smoother and more flavourful than a quick cure.

Extended cure (3-6 months) — Some strains genuinely benefit from longer curing periods. Extended curing can produce exceptional complexity in both aroma and flavour that simply isn’t achievable with shorter cures. Premium AAAA+ flower from quality BC producers often benefits from extended curing.

The economics of cannabis production create constant pressure to rush the cure — every week the product sits in jars is a week of delayed revenue. This commercial pressure is one reason why so much cannabis on the market is under-cured. When you notice that a premium cannabis flower smells and tastes genuinely exceptional, a thorough cure is almost always part of why.

How Freshly Rated Cannabis Ensures Quality

At Freshly Rated Cannabis we source our products from BC producers who respect the drying and curing process. Here’s what we look for:

Proper moisture content — We check that flower has been dried to the appropriate moisture range. Cannabis that crumbles to dust or feels wet or spongy signals problems with the drying process.

Aroma assessment — Properly cured cannabis has a complex, strain-specific aroma. Cannabis that smells like hay or grass hasn’t been cured properly. Cannabis that smells musty or of ammonia has been over-moistened during curing.

Burn quality — When smoked, properly dried and cured cannabis burns consistently and evenly, produces white or light grey ash, and doesn’t require constant relighting. Black ash indicates incomplete combustion from excess sugars or chlorophyll — a sign of inadequate curing.

Flavour — The full flavour expression of a strain is only achievable through proper curing. We know what properly cured cannabis should taste like and apply that standard to everything we list.

This quality assessment process is why customers across Surrey, Vancouver, Burnaby, Langley and the Lower Mainland trust Freshly Rated Cannabis for consistently excellent product.

What This Means for You as a Cannabis Consumer

Understanding drying and curing helps you recognize quality cannabis when you encounter it:

Signs of proper drying and curing:

• Complex, strain-specific aroma — earthy, floral, citrus, pine, or other distinct notes
• Slightly sticky feel — well-cured cannabis has a pleasant stickiness from preserved trichomes
• Springy texture — buds should have some give when gently squeezed, not crumble or stay compressed
• Clean, even burn with light-coloured ash
• Smooth smoke without harsh throat hit
• Full flavour expression

Signs of poor drying or curing:

• Hay or grass smell — inadequate curing
• Ammonia or musty smell — over-moistened during curing, possible mould
• Crumbles to dust — over-dried
• Harsh, throat-irritating smoke — chlorophyll and sugars not adequately broken down
• Black ash — incomplete combustion from residual compounds
• Bland flavour — terpenes lost through rapid drying

Frequently Asked Questions — Cannabis Drying and Curing BC

Why does some cannabis smell like hay or grass? The hay or grass smell in cannabis indicates inadequate curing. It means chlorophyll hasn’t been fully broken down during the cure. The cannabis is technically smokeable but will be harsher and less flavourful than properly cured flower.

How can I tell if cannabis has been properly cured? Properly cured cannabis has a complex, strain-specific aroma — not a grassy or generic smell. It burns evenly with light-coloured ash, produces smooth smoke, and has a pronounced flavour. Buds should feel slightly sticky and have some spring when gently squeezed.

Does curing increase THC content? Curing allows biosynthetic processes to continue after harvest — non-psychoactive cannabinoids can continue converting to THC-A during curing. Additionally, by breaking down compounds that interfere with the smoking experience, proper curing makes the THC that is present more accessible and effective.

Can I get properly cured cannabis delivered same day in Surrey? Yes — Freshly Rated Cannabis sources from quality BC producers who respect the curing process. Our full range of properly cured cannabis is available for same day delivery across Surrey and the Lower Mainland. Free delivery on orders over $50 in Surrey.

What is the difference between AA and AAAA cannabis in terms of curing? Premium AAAA and AAAA+ cannabis typically benefits from longer, more carefully controlled curing compared to budget AA flower. This extended curing is one of the factors that distinguishes truly exceptional top-shelf cannabis from more budget-friendly options — and contributes to the price difference.

Why does cannabis from quality dispensaries taste better? Multiple factors contribute — genetics, growing conditions, harvest timing, and post-harvest handling including drying and curing. Quality cannabis dispensaries and delivery services like Freshly Rated Cannabis source from producers who get all of these factors right, which is why the difference in your experience is noticeable.
