Harvesting, Drying & Curing

The Final Steps to Quality Cannabis

The harvesting, drying, and curing processes are critical final steps that dramatically impact the quality, potency, flavor, and smoothness of your cannabis. Even perfectly grown plants can be ruined by improper post-harvest handling, while average plants can be elevated with proper technique. For a full overview of the plant's life cycle, see the Cannabis Growth Timeline. For troubleshooting, try our Plant Diagnosis Tool. For growing setup, see Indoor Growing or Balcony & Outdoor Growing.

These final stages require patience and attention to detail. In Malta's unique climate, specific adaptations to standard techniques are necessary to achieve optimal results. This chapter covers everything from determining the perfect harvest moment to properly storing your finished product.

Why These Final Steps Matter

Many new growers focus intensely on the growing phase but underestimate the importance of proper post-harvest processing. Here's why these final steps are crucial:

Malta Consideration

Malta's Mediterranean climate presents both advantages and challenges for post-harvest processing. While the generally dry conditions can help prevent mold, summer humidity and occasional rapid weather changes require special attention during drying and curing.

Determining the Perfect Harvest Time

Knowing exactly when to harvest is crucial for maximizing potency and achieving your desired effects. Cannabis harvested too early will be less potent and may produce more energetic effects, while cannabis harvested too late will have more sedative effects and potentially reduced THC levels.

Visual Indicators of Readiness

There are several visual cues that help determine when your plants are ready for harvest:

Pistil Observation

â–¼

Pistils are the hair-like structures that protrude from the buds. Their color and position change as the plant matures:

  • Early stage: White pistils standing straight up
  • Mid maturity: 50-70% of pistils have darkened to orange/brown
  • Peak harvest window: 70-90% of pistils have darkened and curled inward
  • Late harvest: Nearly all pistils have darkened and curled tightly inward

While pistil observation is a good starting point, it's less accurate than trichome inspection and can vary by strain. Use this method in combination with trichome examination for best results.

Bud Appearance

â–¼

The overall appearance of buds changes as they mature:

  • Swelling: Buds reach full size and stop expanding
  • Density: Buds feel firm and dense when gently squeezed
  • Trichome coverage: Buds appear frosty with dense trichome coverage
  • Color shifts: Some strains develop purple, blue, or red hues as they mature
  • Leaf changes: Fan leaves may begin to yellow and drop as the plant directs energy to buds

These visual cues vary significantly by strain, so familiarize yourself with the specific characteristics of what you're growing.

Timeline-Based Indicators

â–¼

While less precise than visual inspection, typical flowering times can provide a general guideline:

Cannabis Type Typical Flowering Period Harvest Window
Indica-dominant 7-9 weeks Days 50-65 after flower initiation
Sativa-dominant 10-14 weeks Days 70-100 after flower initiation
Hybrid strains 8-11 weeks Days 56-77 after flower initiation
Autoflowers 10-12 weeks total Days 70-85 from seed

Breeder recommendations should be used as a starting point, but environmental factors, growing conditions, and phenotype variation can all affect these timelines. In Malta's climate, flowering times may be slightly shorter for outdoor grows due to the intense Mediterranean sunlight.

Harvest Window Tip

Different cannabinoids reach their peak at different times. For maximum THC content, harvest when most trichomes are cloudy with few amber ones. For more sedative effects with higher CBN content, wait until 20-30% of trichomes have turned amber.

Trichome Inspection: The Most Accurate Method

Examining trichomes with magnification is the most reliable way to determine harvest readiness. Trichomes are tiny, mushroom-shaped resin glands that contain most of the plant's cannabinoids and terpenes.

Required Tools

You'll need one of the following to properly view trichomes:

Trichomes at different stages of maturity viewed through magnification
Trichomes progress from clear to cloudy to amber as they mature

Trichome Development Stages

Stage Appearance Effect Profile Best For
Clear/Translucent Transparent trichome heads, still developing Underdeveloped, less potent, headier high Too early for optimal harvest
Milky/Cloudy Opaque white trichome heads Peak THC, energetic, cerebral effects Daytime use, creative activities
Amber/Amber Trichome heads turning amber/brown THC degrading to CBN, more sedative Evening use, sleep aid, pain relief

Where to Look

For accurate assessment, examine trichomes in these locations:

Malta Trichome Tip

Malta's bright light might make trichome inspection challenging outdoors. Create shade with your body or a piece of cardboard when using your magnification tool, or take a small sample indoors for examination in controlled lighting.

Recommended Harvest Percentages

As a general guideline, harvest based on these trichome ratios for different effects:

Harvesting Techniques

Once you've determined that your plants are ready, it's time to harvest. The process requires preparation, the right tools, and proper technique to preserve trichomes and maintain quality.

Pre-Harvest Preparation

Set yourself up for success with these pre-harvest steps:

Final Flush (Optional)

â–¼

Many growers perform a flush before harvest to improve flavor:

  • Soil growing: Water with plain pH-adjusted water for 1-2 weeks before harvest
  • Coco/Hydro: Use plain pH-adjusted water for 3-7 days before harvest
  • Signs of successful flush: Yellowing fan leaves, fading color in sugar leaves

Flushing is somewhat controversial among growers. Some scientific studies question its benefits, so consider it optional based on your preferences.

Darkness Period (Optional)

â–¼

Some growers put plants in complete darkness for 24-72 hours before harvest:

  • Potential benefit: May increase resin production and trichome development
  • Indoor application: Simply turn off lights for the final 1-3 days
  • Outdoor application: Move plants to a dark shed or garage temporarily

Like flushing, this technique lacks conclusive scientific evidence but is popular among many experienced growers.

Harvesting Tools & Supplies

â–¼

Gather these supplies before beginning the harvest process:

  • Sharp pruning shears: Clean and disinfected with rubbing alcohol
  • Trimming scissors: Sharp, precise scissors for manicuring buds
  • Gloves: Powder-free latex or nitrile (prevents sticky resin on hands)
  • Trim tray: To collect valuable fallen trichomes
  • Clean containers: For collecting trimmed buds
  • Alcohol wipes: For cleaning sticky scissors during trimming
  • Drying rack or hanging system: Ready before cutting begins

Quality tools make the process faster and more precise. Invest in good scissors and keep them clean throughout the process.

Harvesting Methods

There are two primary approaches to harvesting cannabis:

Whole Plant Harvest

â–¼

Process:

  1. Cut the main stem just above the soil line
  2. Hang the entire plant upside down
  3. Remove large fan leaves
  4. Allow the entire plant to dry before further processing

Advantages:

  • Simplest method for beginners
  • Slower drying process (typically desirable)
  • Less handling of buds preserves trichomes
  • Easier to manage large harvests

Disadvantages:

  • Requires more vertical space for drying
  • Limited control over drying for individual branches
  • Not ideal for plants with uneven ripening

Sectional Harvest

â–¼

Process:

  1. Divide the plant into main branches or sections
  2. Cut branches individually
  3. Hang branches separately
  4. Remove fan leaves

Advantages:

  • Better for smaller drying spaces
  • More control over the drying process
  • Allows for staggered harvest based on readiness
  • Easier to manage uneven plants

Disadvantages:

  • More time-consuming initially
  • More handling might reduce trichomes slightly
  • Can dry slightly faster (requires more monitoring)

Progressive Harvest

â–¼

Process:

  1. Harvest top colas first when they mature
  2. Leave lower buds to continue developing
  3. Return for a second harvest 1-2 weeks later
  4. Potentially continue for a third harvest if necessary

Advantages:

  • Maximizes yield as lower buds receive more light
  • All buds can reach optimal maturity
  • Spreads out processing work
  • Particularly effective for sativa-dominant strains with uneven ripening

Disadvantages:

  • More complex and time-consuming
  • Requires more ongoing attention
  • More stressful for the plant
  • Not ideal for autoflowering varieties

Malta Harvest Timing Tip

In Malta's climate, early morning is the best time to harvest. The cooler temperatures preserve terpenes better than harvesting during midday heat, and plants tend to have higher concentrations of essential oils before experiencing the day's heat.

Trimming Methods: Wet vs. Dry

Trimming removes excess leaf material from buds and improves appearance, smokability, and in some cases, potency. There are two main approaches: wet trimming (immediately after harvest) and dry trimming (after drying).

Wet Trimming

Definition: Trimming buds immediately after harvesting, while plant material is still moist and flexible.

Advantages:

  • Easier and faster as leaves stand out more
  • Less space required for drying
  • Potentially lower risk of mold in humid environments
  • More manicured appearance for commercial appeal
  • Trim is fresher for extracting

Disadvantages:

  • Faster drying time (sometimes too fast)
  • Potentially harsher flavor due to rapid drying
  • More trichome loss during handling
  • Very sticky process that coats hands and tools

Dry Trimming

Definition: Trimming buds after the drying process is complete, when leaves are crisp and stems snap.

Advantages:

  • Slower, more controlled drying process
  • Better terpene preservation and flavor
  • Less sticky, easier to handle
  • Sugar leaves protect trichomes during drying
  • Less immediate work post-harvest

Disadvantages:

  • More difficult to get a close trim
  • More space required for drying whole branches
  • Higher mold risk in humid environments
  • Brittle trichomes can break off during handling

Malta Trimming Recommendation

For Malta's climate, wet trimming is often recommended during the more humid winter months (October-March) to reduce mold risk. During the dry summer months (April-September), dry trimming can provide better flavor and a more controlled drying process. Adjust based on your specific microclimate and indoor conditions.

Trimming Technique

Regardless of whether you choose wet or dry trimming, the basic technique remains similar:

  1. Remove fan leaves: Large leaves with stems, either by hand or with scissors
  2. Trim sugar leaves: Smaller leaves protruding from buds, leaving a manicured appearance
  3. Maintain bud structure: Trim closely without damaging the bud structure
  4. Periodically clean tools: Use alcohol wipes when scissors get sticky
  5. Save trim: Collect sugar leaves for extractions, edibles, or other uses

Trimming Process Step by Step

â–¼
  1. Prepare your workspace: Clean surface, comfortable seating, good lighting
  2. Put on gloves: Prevents resin buildup on hands
  3. Remove fan leaves: Pull large leaves with stems (save for compost)
  4. Separate buds: Cut individual buds from the main stem (if wet trimming)
  5. Trim sugar leaves: Cut leaf material that extends beyond bud profile
  6. Shape buds: Create uniform appearance without compressing the bud
  7. Clean and rotate: Clean scissors frequently and rotate buds to ensure even trimming
  8. Collect different materials: Keep buds, sugar leaves, and fan leaves separated

For best results, take your time and work in sessions of 1-2 hours to maintain precision and avoid fatigue. Rushing leads to accidental cuts into the bud structure or uneven trimming.

Different Trim Levels

â–¼

The amount of trimming is somewhat subjective and depends on your preferences:

  • Commercial trim: Very close trim with minimal leaf material, maximizing bud appearance
  • Moderate trim: Removes obvious leaves while leaving some small sugar leaves with high trichome content
  • Natural trim: Minimal trimming, removing only large leaves for a more natural appearance (often preferred for personal use)

Personal preference matters here. Some connoisseurs prefer a moderate trim with some sugar leaves intact, as these leaves are rich in terpenes and contribute to flavor complexity.

The Drying Process

Proper drying is critical for quality cannabis. Drying too quickly can trap chlorophyll and sugars in the buds, resulting in harsh smoke and a "hay" smell. Drying too slowly increases the risk of mold. In Malta's climate, special attention to humidity control is essential.

Creating the Ideal Drying Environment

The perfect drying environment balances several key factors:

Environmental Parameters

â–¼

Maintain these ideal conditions:

  • Temperature: 15-21°C (60-70°F), never exceeding 24°C (75°F)
  • Humidity: 45-55% relative humidity
  • Air circulation: Gentle, indirect airflow
  • Light: Dark or very dim light to preserve cannabinoids
  • Odor control: Carbon filter if smell is a concern

These parameters allow for a 7-14 day drying process, which is ideal for preserving terpenes and cannabinoids while eliminating chlorophyll.

Drying Setup Options

â–¼

Several methods can work depending on your space and budget:

  • Hanging method: String or wire across a room, hang branches upside down
  • Drying rack: Mesh racks with multiple levels for buds (better for wet-trimmed buds)
  • Cardboard box: DIY option with holes poked for airflow and string across the top
  • Modified closet: Small space with a fan for circulation and hygrometer for monitoring
  • Commercial drying tent: Purpose-built tent with humidity/temperature control

Whichever method you choose, ensure air can circulate around all buds, and material doesn't touch or overlap.

Climate Control Equipment

â–¼

In Malta, you may need these tools to maintain ideal conditions:

  • Hygrometer: Essential for monitoring humidity (€10-30 for digital)
  • Dehumidifier: For reducing humidity during rainy/humid periods
  • Humidifier: For increasing humidity during very dry periods
  • Fan: Small oscillating fan for air circulation (never pointing directly at buds)
  • Air conditioner: For controlling temperature during hot periods
  • Heater: Rarely needed in Malta, but occasionally helpful in winter

The minimum equipment needed is a good hygrometer and fan. Add humidity control equipment based on your local conditions and season.

The Drying Timeline

A proper drying process follows this general timeline:

Stage Timeline What to Expect What to Do
Initial drying Days 1-3 Surface moisture evaporates, buds feel moist but not wet Maintain airflow, check humidity 2x daily
Mid drying Days 4-7 Smaller stems become bendable, buds shrink slightly Monitor for any mold signs, adjust humidity if needed
Late drying Days 8-12 Small stems snap, buds feel dry on outside but slightly moist inside Begin testing small stems for proper dryness
Completion Days 10-14 Stems snap cleanly, buds feel dry but not brittle Trim (if dry trimming) and move to curing

Malta Drying Challenge

In Malta's summer months (June-August), high temperatures can cause buds to dry too quickly. Consider drying in the coolest room of your home, often on the first floor or in a cellar. If necessary, use a small air conditioner to maintain temperatures below 24°C. During winter (December-February), increased humidity may require a dehumidifier to prevent mold issues.

Knowing When Drying is Complete

The most reliable methods to determine when your cannabis is properly dried:

Don't rush this process. Underdried cannabis risks mold during curing, while overdried cannabis loses potency and flavor. Aim for the slower side of the drying timeline for best results.

The Curing Process

Curing is a controlled aging process that allows the chemical breakdown of residual sugars and chlorophyll. Proper curing dramatically improves flavor, aroma, and smoothness while extending shelf life and preserving potency.

Container Options

The container you choose impacts the curing process:

Glass Jars

â–¼

Advantages:

  • Airtight seal preserves terpenes
  • Doesn't impart any flavors
  • Easy to monitor moisture levels visually
  • Available in many sizes
  • Widely available in Malta (grocery stores, home goods stores)

Disadvantages:

  • Breakable
  • Transparent (requires dark storage)
  • Limited size options for large harvests

Best practices: Use wide-mouth jars filled 75% to allow some air space. Mason jars or preserving jars with rubber seals work best. Store in a dark cabinet or use amber/blue glass jars to prevent light degradation.

Alternative Containers

â–¼

Other options include:

  • CVault containers: Metal containers with humidity packs built in
  • Miron glass: Violet glass that blocks harmful light spectrums
  • Stainless steel containers: Durable and lightproof
  • Plastic containers: Not recommended (can create static and affect flavor)
  • Ceramic containers: Work well if they have airtight seals

Glass remains the most widely used and recommended option, but any airtight, neutral container that doesn't impart odors or flavors can work.

Humidity Control Products

â–¼

These products help maintain optimal humidity during curing:

  • Boveda packs: Two-way humidity control packs (58% or 62% recommended)
  • Integra Boost: Similar to Boveda with different size options
  • Humidity beads: Reusable humidity control option

These products aren't strictly necessary but provide insurance against over-drying or over-humidification, especially in Malta's variable climate.

Where to find in Malta: Humidity packs can be ordered online, but might not be available in local stores. Some smokers' shops in St. Julian's and Paceville occasionally stock them.

The Curing Process Step by Step

  1. Prepare containers: Clean and fully dry your jars or containers
  2. Fill containers: Place buds loosely in jars, filling about 75%
  3. Initial monitoring: Seal and store in a cool, dark place
  4. Burping schedule: Open jars daily for the first week to exchange air
  5. Check for moisture: If buds stick together or feel damp, remove for a few hours
  6. Adjust schedule: After the first week, reduce burping to every 2-3 days
  7. Extended curing: After 2-3 weeks, burp weekly until desired cure is reached

Curing Duration Tip

While cannabis is smokable after 2-4 weeks of curing, extending the process to 4-8 weeks significantly improves quality. Some connoisseurs cure for 6+ months for premium results, similar to aging fine wine. The minimum recommended cure time is 30 days.

Curing Timeline and Effects

Timeline Expectations Changes Occurring
Days 1-7 Grassy smell may persist, moisture redistribution Initial breakdown of chlorophyll, daily burping crucial
Weeks 2-3 Grassy smell diminishes, true strain aroma emerges Continued chlorophyll breakdown, terpene stabilization
Weeks 4-6 Smooth smoke, full flavor profile developing Sugars and starches break down, cannabinoid stabilization
Months 2-3 Premium quality, complex aroma, smooth smoke Full terpene expression, maximum smoothness
Months 4-6+ Connoisseur quality, nuanced flavor profile Subtle chemical changes, similar to fine wine aging

Long-Term Storage

After the initial curing period, cannabis can be stored for extended periods with these guidelines:

Under ideal conditions, properly cured cannabis can maintain quality for 1-2 years. Some cannabinoid degradation is inevitable over time (THC gradually converts to CBN, creating more sedative effects).

Troubleshooting Common Issues

Even with careful attention, problems can arise during the harvesting, drying, and curing process. Here's how to identify and address common issues:

Mold During Drying

â–¼

Symptoms:

  • White, fuzzy growth on or between buds
  • Musty, mildew smell
  • Darkening or discoloration of affected areas
  • Web-like structures when buds are broken apart

Causes:

  • Excessive humidity (>60% RH)
  • Poor air circulation
  • Buds too close together
  • Insufficient branch trimming

Solutions:

  • Immediately remove affected buds
  • Increase airflow with fans
  • Add dehumidifier if needed
  • Separate remaining buds further apart
  • Check every bud carefully for signs of spread

Prevention:

  • Maintain humidity below 60%
  • Ensure good air circulation
  • Inspect daily for early signs
  • Consider wet trimming in humid conditions

Safety Warning

Never consume moldy cannabis. Mold spores can cause serious respiratory issues and allergic reactions. If in doubt, discard affected material.

Overdried Cannabis

â–¼

Symptoms:

  • Buds crumble easily when touched
  • Harsh smoke with little flavor
  • Brittle stems that snap with minimal pressure
  • Buds sound "crunchy" when squeezed gently

Causes:

  • Too much airflow during drying
  • Low humidity environment
  • Extended drying period
  • High temperatures during drying

Solutions:

  • Add Boveda or Integra humidity packs (62%)
  • Place a small piece of fresh orange/lemon peel in jar for 12 hours (monitor closely)
  • Add a small piece of fresh lettuce leaf to jar for a few hours
  • Use a hydrating stone (soak in distilled water)

Rehydration is possible but will not fully restore lost terpenes. Prevention is always better.

Jars Too Humid During Cure

â–¼

Symptoms:

  • Buds feel damp or spongy
  • Moisture appears on inside of jar
  • Buds stick together when moved
  • Ammonia or sweet/fermented smell

Causes:

  • Buds not dried sufficiently before jarring
  • Jar filled too tightly
  • Insufficient burping schedule
  • Large buds with moisture trapped inside

Solutions:

  • Immediately remove buds from jars
  • Spread on paper for a few hours or up to 24 hours
  • Increase burping frequency when returned to jars
  • Add 58% humidity packs when stability is reached

Ammonia Warning

If buds develop an ammonia smell, they are beginning to rot. Remove immediately, dry thoroughly, and discard any that maintain the smell after drying.

Loss of Smell/Flavor

â–¼

Symptoms:

  • Hay-like or grassy smell persists after weeks of curing
  • Lack of characteristic strain aroma
  • Flat or muted flavor profile
  • Harsh smoke without complexity

Causes:

  • Drying too quickly (high heat or excessive airflow)
  • Light exposure during drying or curing
  • Rough handling breaking trichomes
  • Air exposure from excessive burping

Solutions:

  • Continue curing for extended period (some improvement possible)
  • Ensure proper storage conditions
  • Use humidity packs to stabilize conditions
  • Try vacuum sealing for long-term storage

Prevention is key, as lost terpenes cannot be replaced. Focus on slow drying (10-14 days) in future harvests.

Malta-Specific Troubleshooting

Due to Malta's fluctuating seasonal humidity, invest in a good hygrometer that tracks humidity history. This allows you to identify patterns and respond to changing conditions before they cause problems. During sirocco wind events (hot, dusty winds from North Africa), take extra precautions with ventilation and humidity control, as these dramatic weather changes can quickly impact drying conditions.
