Cannabis Drying and Curing Guide: Enhancing Scent & Quality

We all appreciate the distinct and delightful aroma of cannabis – that earthy, musky, and sweet fragrance. Proper Cannabis drying and curing contributes significantly to these.

However, sometimes, especially after harvesting and during the curing process, your cannabis might develop an undesirable hay-like smell.

Fear not! In this guide, we’ll explore why this happens and, more importantly, how to avoid it to ensure your weed remains top-notch.

Why Is My Weed Going Bad?

The hay or grass smell in your cannabis is due to chlorophyll. If you dry and cure your cannabis properly, the chlorophyll breaks down, and the smell disappears. This process happens slowly. If you are drying your cannabis so fast, the chlorophyll won’t have enough time to break down, but don’t worry – with patience, the smell will fade within four weeks, and you can still enjoy your cannabis.

While your cannabis will be okay, the downside is that it might not reach its full potential. The same mistakes causing the unpleasant smell may have damaged some terpenes, affecting the overall potency and flavor of the bud. It may also effect the Thc levels and you can end up with a lower Thc!

Cannabis Drying and Curing – Done right!

Getting the drying and curing processes right is super important for making sure your cannabis turns out top-notch. These two steps are different but equally crucial. Paying close attention to details is key for the best results. It’s essential to understand that drying and curing are not the same – drying comes first and usually takes about a week or ten days. After that, your cannabis needs to go through curing for at least two to three weeks. If you can wait longer, it’ll make the smoking experience smoother and more enjoyable. Now, let’s break down these important steps in a simple guide:


  • Hanging Method: Begin by trimming your cannabis branches and hanging them upside down from a wire or string. This encourages an even drying process. If you are planning a dry trim, just trim the fan leaves before hang them!
  • Dark Environment: Store the drying cannabis in a completely dark room to prevent exposure to light, which can degrade cannabinoids and terpenes.
  • Temperature and Humidity Control: Maintain a temperature range between 16 and 21 degrees Celsius, with humidity levels kept at 45-55%. These conditions help preserve the delicate balance between moisture content and terpene retention.
  • Air Circulation: Introduce a gentle fan in the drying room to circulate air. Ensure that it doesn’t blow directly onto the buds to prevent trichome damage.
  • Monitoring Progress: Regularly check the drying buds. When smaller branches snap instead of bending, and the flowers feel slightly crunchy, it’s time to move on to the curing phase.


  • Trimming and Manicuring: After the drying phase, trim the buds from their branches and perform any necessary manicuring.
  • Airtight Containers: Place the trimmed buds in airtight containers, such as Mason jars. Avoid packing the jars tightly; leave some space for air circulation.
  • Storage Conditions: Store the containers in a cool, dry, and dark location to maintain an ideal environment for the curing process.
  • Regular Inspection: Check the buds daily. Over the first week, allow the containers to remain open for a few minutes to facilitate moisture evaporation. If an ammonia smell is detected, it indicates excess moisture and potential bacterial issues.
  • Continued Evaporation: For the subsequent weeks, open the jars once a day to continue the moisture evaporation process.
  • Patience Pays Off: While your cannabis may be pleasant to smoke after 2-3 weeks of curing, the flavor and smoothness will significantly improve if you can resist temptation and extend the curing period to eight weeks. This extended time allows for the breakdown of chlorophyll, resulting in a smoother smoke.

By following these detailed steps for drying and curing, you can elevate the quality of your cannabis to deliver a truly exceptional smoking experience. Patience and attention to detail are key to unlocking the full potential of your harvest.
