Mastering the Art of Curing and Preservation for Your Homegrown Colorado Cannabis

Growing weed in Colorado is a rewarding process - but don’t stop celebrating after harvest. To get the most out of your homegrown buds, you’ll need to master the curing and preservation process. Done right, curing enhances potency, improves flavor, extends shelf life, and protects your stash from mold. 

Let’s walk through the detailed steps of post-harvest care, specifically tailored for Colorado’s unique climate.

Why Curing Matters (and Why It’s Not the Same as Drying)

Drying removes surface moisture.
Curing slowly draws out internal moisture while allowing chemical processes to continue - like chlorophyll breakdown and terpene development. Think of it like aging cheese or wine: time transforms good into great.

Skipping or rushing curing can leave you with harsh, grassy, or flavorless buds - even if you nailed the grow.

Step 1: Dry Your Buds (But Don’t Bake Them!)

Ideal conditions for Colorado’s arid air:

• Temperature: 60–70°F
• Humidity: 55–65% RH
• Drying time: 5–10 days
• Airflow: Gentle and consistent
• Darkness: Keep lights off to preserve cannabinoids

Hang whole branches or trimmed buds upside down in a dedicated drying space. In Colorado, especially at elevation, low humidity can cause buds to dry too quickly - so consider using a small humidifier or hanging whole plants to slow the process.

Tip: Buds are ready when small stems snap, not bend.

Step 2: The Cure – Low and Slow

Once dry, place buds in glass jars (mason jars work great). Fill them about 75% full to allow for airflow. Plastic and metal can leach flavors or affect humidity—stick to glass.

The curing environment:

• Humidity: 58–62% RH (use humidity packs to stabilize)
• Temperature: 60–70°F
• Location: Cool, dark place away from sunlight

Open the jars ("burping") once or twice a day for the first 7–10 days to release excess moisture and refresh the air. Check for any signs of mold or too-wet buds.

After 2–4 weeks, the harshness fades and flavor starts to shine. Some connoisseurs cure for up to 8 weeks for the smoothest, richest smoke.

Step 3: Long-Term Storage in Colorado’s Dry Air

Colorado’s dry climate is great for skiing - terrible for storing cannabis. Without proper preservation, your buds can dry to dust in weeks. Here’s how to store long-term:

Use:

• Glass jars with airtight seals
• Humidity packs (58–62%)
• Dark storage boxes or cabinets
• Vacuum-sealed containers (for very long-term or backup storage)

Avoid:

• Plastic bags (they let moisture in/out)
• Refrigerators (cause humidity swings)
• Freezers (can damage trichomes)

Label each jar with strain, harvest date, and cure start date - your future self will thank you.

Bonus: Preserving Terpenes Like a Pro

Colorado-grown cannabis often has strong terpene profiles thanks to sunny days and clean mountain air. To keep that citrus, pine, or diesel aroma intact:

• Never over-dry (below 55% RH will cause terpenes to evaporate)
• Store in cool, dark places
• Minimize handling after cure
• Keep lids closed unless you’re sampling

A Note on Mold and Humidity in Colorado Basements

Though Colorado is generally dry, basement grows can retain humidity - especially in spring. Always monitor humidity closely. If RH spikes above 65% during cure, buds are at risk for mold. Use hygrometers in your jars to stay ahead of problems.

Curing Is the Craft

You didn’t just grow weed - you crafted it. Curing and preservation are your final tools to ensure each nug delivers on all the potential you grew into it. With a little patience and the right environment, you’ll end up with smooth, potent, flavorful buds that last for months (if you don’t smoke them all first).
