The process of drying weed consists of evaporating most of the water in the buds, to do this you need to maintain the temperature around 20°C and humidity ranging from 45-50%. Even though it sounds easy enough, there is a right way and wrong way to do it and each can be the difference between chunky, incredible-smelling flowers with the ultimate bag appeal, or a flat-looking flower that has a minimal aroma with a fresh chlorophyll taste.


Sebastian Good talks about the best way to dry Autoflowering Cannabis.

In this article, we explain how to dry bud properly, the correct dry room scenario, and our top tips for drying buds to perfection.

1. How to Tell When Your Crop is Ready for Harvest

Ok before we dive deep into the ocean of variables involved with correctly drying and curing your cannabis crop, let's look at how you can correctly identify plants that are ready to be chopped down. Now we all know that every seed you buy online will come with some timing guidelines. That's no different here at Fast Buds, but unlike a bunch of the other seed banks, we are more than willing to say they are just that - guidelines. There are so many factors that go into cannabis growth and development, and so there is simply no way for a seed company to know exactly how long each individual seed will take to go from germination to harvest.

What we can say is that the timing guidelines we offer are for plants that have been exposed to optimal conditions throughout the entire lifecycle.  We're talking about the right soil mix (or hydro setup), ideal temperatures and humidity levels, perfect lighting, etc. So if your grow room isn't quite up to snuff, or you just got a little lazy with your feeding schedule, your plants might not be ready to harvest when the package says they should be. But don't worry, if you are growing Fast Buds genetics then no matter what conditions your crop has been exposed to, you will end up with top-shelf, gorgeous buds within a week or so of what the package says.

Ok, so how do you tell exactly when the plants are ready to head to the dry room?

The best way to determine when your crop is ready for harvest is by using a jeweler's loupe or portable USB microscope to closely inspect the trichomes on the buds.  Trichomes are tiny, crystal-like hairs that cover the buds and leaves of the cannabis plant. They are what give the buds that frosty look and they are also where all the cannabinoids and terpenes are produced (the good stuff).


How to dry cannabis: how to tell when to harvest

You will need a jeweler's loupe or microscope to check the trichomes!

To be honest, while jewelers' loupes will allow you to see what's going on, portable USB microscopes have come down in price dramatically in recent years and just make the job that much easier. Make sure you pick one up that has an inbuild LED lighting option, and that can connect to either your smartphone or computer. This allows you to take snapshots and save them.  They can be found in a range of retail stores, and your local hydro supplier should have them in stock. Or, alternatively, they can be found on Amazon.

Right, so what should you be looking for?

Trichomes go through three distinct stages - clear, cloudy, and then finishing up at amber. You want to harvest when the majority of trichomes have turned cloudy, with just a few amber ones mixed in. If most of the trichomes are still clear, your buds are not quite ready. And if most of them are already amber, you've left it too long and your buds will be less potent and have more of a couch-lock effect.

The sweet spot is when 60-70% of the trichomes have turned cloudy, with the remaining 30-40% being a mix of both clear and amber. This is what we are aiming for at Fast Buds, as it results in buds that are packed with flavor, highly potent, and offer a balanced high that is not too heavy. Of course, at the end of the day, it is completely up to you when you harvest your crop.  If you want buds that are a little more couch-locking, wait until most of the trichomes have turned amber. If you want something a little lighter, harvest when the majority are still clear.  It's really up to you and what you are looking for in your final product.

2. Trimming Your Cannabis

When harvesting your plants, you will have to decide on whether to trim the excess foliage before or after drying them, now this isn’t a problem at all but depending on your drying room, you should wet trim rather than dry trim.

Wet trimming

Wet trimming consists of trimming your plants before the drying process, this is the most preferred methods by several growers because the moisture in the leaves can end up affecting the humidity level in your drying room, also, you’ll be able to use the fresh trimmings to make extracts, lotions, oils or even edibles.


How to dry cannabis: wet trimming

Wet trimming consists of trimming your cannabis before drying them.

Dry trimming

Dry trimming on the other hand consists of trimming your flowers after the drying process, a lot of growers prefer this way because it can get quite messy when cutting leaves from fresh plants. 


How to dry cannabis: dry trimming

Dry trimming consists of trimming your bud after drying it.

But you should have in mind that it’s recommended to dry trim only if you are able to control the conditions in the drying room because the excess moisture can end up molding your buds.

3. Placing Your Buds In The Drying Room

So, after trimming (or before if you’re dry trimming) you will have to hang up the branches in your drying room, this consists of just hanging the flowers to dry and you can do it in a rack, or on a rope similar to a clothesline, but first, you need to know how you’ll harvest your plant.


How to dry cannabis: dry trimming

Cannabis plants after harvest all ready to start drying.

There are several ways to chop your plant, you can harvest your plant and hang it whole, cut each branch individually or cut each individual bud, and depending on which one you prefer, the way you hang them will differ a bit.

Hanging the branches on a rope

If you harvested your plant branch by branch or you cut the plant whole, you will need a clothesline or a similar rope to hang them, this is usually the preferred method because the branches still have water inside them, so it will prevent your buds from speed drying. Obviously, you will still have to control the conditions (if possible) but this could be used as a safety precaution in case you’re worried.


Pros and Cons of Hanging vs Drying racks
 HangingDrying rack

- Cheap;

- Slower drying.

- Better organization;

- Dry faster.


- Slower drying can result in mold;

- Needs a lot of space.

- Can lower quality if not controlled;

- Can be expensive.


Drying the buds on flat racks

Flat racks are vertical racks that came with several flatbeds, these racks are mainly used when drying individual buds and are a great way to save space because some of them come with up to 5 flatbeds, meaning you can dry more flowers in the same amount of space that you would when hanging the branches. Obviously, this comes with a downside, due to the flowers not having branches, it is possible for them to dry faster that you would like to so it’s essential to have the drying conditions controlled to avoid problems.

4. The Dry Room

For those new to growing Cannabis, have a clear understanding of exactly what occurs in the drying room is essential. The aim is to slowly dry the flowers for around 15 days which happens so it’s a matter of experimenting with different temperatures and humidity levels to get to that sweet spot, which can differ depending on where you live.


Sometimes it is not possible to control the temperatures of your drying room, however, you should aim for 20°C which is the ideal temperature in most cases. It is much better to dry the buds slowly at a lower temperature to prevent the cannabinoids and terpenes from evaporating.

If you have a temperature fan controller, setting it to 20°C and humidity around 50% will allow the drying room to stay consistent.


How to dry cannabis: best conditions

Ideal conditions to dry your cannabis properly.

Humidity levels

If the goal is to reduce the moisture in the flowers down to the point it is ready for curing jars, then it is necessary to do this process slowly. Keeping humidity levels at 40-50% will encourage the flowers to air out in their own time, and once the flowers are close to dry, then they can be placed in an airtight curing jar, from where they will reduce down further.

Use Boveda packs or something similar to ensure your buds are kept at an optimal humidity while curing.

Air Flow

A very important part of the drying room is that you cannot let your harvest dry out too quickly. You should never have a fan blowing directly at the flowers, and the airflow in the room should be very light and fresh. If using a fan, point in the direction away from the buds and have it blowing to the floor or the ceiling. Using fans in a warm environment is the number one cause for harsh-tasting flowers because they’ll have a similar flavor and aroma as they would have if speed dried.

It is better to have very low airflow, however a gentle circulation of air in the dry room is ideal, as well as maintaining your plants in complete darkness. 

Light or Dark?

The drying room should be a cool and dark place, that should not have any light entering or hitting the buds. As plants are left to die on the vine and hang up in the dry room, keeping them in darkness will guarantee the chlorophyll aroma and taste are totally removed, leaving behind terpene-rich, aromatic flowers.


How to dry cannabis: darkness

Your plants should be in a cool place and in completely darkness when drying.

Once the harvested plants are inside the drying room, there is no need to return until the two-week mark, so keeping the room in total darkness is not an issue.

5. How Long Should Buds Take To Dry?

When harvesting the flowers off a Cannabis plant, their buds should be left in a dry room that meets the optimum conditions. It is during this time that the moisture levels are reduced from 80% down to 25-30% depending on curing criteria.


How to dry cannabis: how long?

Flowers should take a minimum of 2 weeks to dry to allow them to get rid of chlorophyll.

Buds should be left to dry for a minimum of 15 days until they’re relatively hard to the touch and the twigs and branches bend but do not crack completely.

What To Remember

  • Freshly harvested plants should take a full 2 weeks to be fully dried. 
  • Smaller-sized buds or wet trimmed buds may be ready in 10 days. 
  • The dry room will slowly reduce the moisture content of the flowers. 
  • This is where the chlorophyll will die off and the fresh smell will go.

6. Speed Drying

We have all probably been guilty of this at some point, and there is nothing worse than speed drying a crop. If intentional or not, the end result always lacks a full aroma and flavor. Speed drying basically means the crop has been rushed and dried in 3-5 days maximum due to high temperatures and excessive airflow directly on the flowers.


How to dry cannabis: speed drying

You should avoid speed drying because your flowers will end up tasting like hay.

When a flower is dried so quickly, it will not have a chance to eliminate the chlorophyll that was present only a week prior. The color of the buds will also have a darker shade of green than normal and the smaller leaves wrapped around will be bone dry and when grinding the flowers, the majority will become dusty.

7. Smell Proof The Dry Room

Drying your freshly harvested Cannabis plants in a smell-proof environment should be a grower's main concern for a number of reasons, the main one being to prevent neighbors from catching a whiff of your high grade.


How to dry cannabis: carbon filter

A carbon filter is the best way to eliminate the strong smell during the drying process.

This will allow you to place the buds inside your grow tent for the next 2 weeks without worrying due to the carbon filter and extraction unit.

Avoid placing your flowers inside a cardboard box or leaving them hanging on an old cupboard, and treat them with extreme delicacy.

8. What To Consider When Drying Cannabis Buds

Step 1

Be patient and wait until the buds are ready. It can be extremely tempting to keep on taking flowers as the flowers are drying, and sometimes the only choice for some growers have. However, patience will reward you with the best tasting, smelling, and looking flower possible.

Step 2

The way to test if your flowers are dry enough to be cured, is to take a bud and snap the smaller twigs. If the twig feels hard and snaps easily then you are good to go. Remember that the bigger branches should not snap, they should bend easily but the fibers should not rip completely, this is when you should cure your flowers.

Step 3

For the sake of smell proofing your drying room, use a grow tent that is equipped with a carbon filter. Grow tents are cheap and converting it into a permanent drying room is well worth the investment in the long run.

Step 4

The chlorophyll and fresh smell will disappear once the flowers have been properly dried. If the buds contain a fresh or hay aroma then the buds are not dry yet or the flower has been dried too quickly. 

Step 5

If you are going to use an oscillating fan, turn the fan away from the flowers so the air is blowing around the room, and off the floor. The key is to have a soft, freeze cool breeze circulating the room, as opposed to warm air blowing around at a fast rate.

Step 6

Flowers that were infected with mold should not be dried and are not suitable for consumption. Smoking contaminated flowers or extracts can cause serious health issues.

9. How to Build a Do-It-Yourself Dry Room for Your Cannabis Crop

There are a bunch of ways to throw together an area that can be used for drying your sticky ganja, but the easiest and most cost-effective is the cardboard box method. Actually, the easiest and most cost-effective is using your grow tent, but that results in a pause in growing time (so maybe less cost-effective?). In either case, it's a fun little project that can be knocked out in less than an hour, so let's get into how to build your very own DIY cardboard box dry room. Materials needed -


  • A cardboard box. The size will be determined by the amount of bud you want to dry, but its best to go bigger than having to build a second or third one when you inevitably run out of space. A standard refrigerator box is usually big enough for 2 or three indoor plants.
  • Some wire, twine, or thin rope. This will be used to hang the buds from. Cheap twine actually does a great job, as the furriness of it tends to kind of grab the buds and keep them in place.
  • A small computer fan and a 9V battery to power it. This inst absolutely necessary, but it will help circulate air in the box and should help keep moisture levels to a minimum.
  • A small roll of duct tape.
  • A pair of scissors.
  • A box cutter.
  • A Phillips head screwdriver
  • Some cheap mesh.


So, the process of building that DIY dry box is as follows.


1. Let's cut the air intake and exhaust holes first. Using the box cutter, cut an intake hole near the bottom of the box. this should be about 4 inches high and 8 inches long. If you are worried about pests getting in and eating your buds you can cover the whole with mesh. The exhaust hole goes near the top of box and should fit the computer fan snuggly.


2. Using the screwdriver, make a series of holes at regular intervals up and down the box on two opposing sides.


3. Run the twine through these holes to create lines for the buds to hang on.


4. Use the to seal up any holes or cracks in your box, but remember to leave the top flaps. This is the entry point, and where you load the buds in and out.


5. Additionally, you can cut a small door halfway down the box. If you are using an oversized box then this will help with hanging your buds.


6. Once the buds are all hung up, put the box in a spot out for direct sunlight and somewhere without too much heat or humidity.

10. Most Common Mistakes When Drying Cannabis

Make sure no light reaches your buds

Strong light can end up evaporating the terpenes and cannabinoids, and your flowers will end up tasting and smelling like hay so make sure your drying room is light-proof.

What to do if your buds are too dry?

If you’ve let your flowers dry for too long or dried them too fast, it’s possible some of the terpenes and cannabinoids evaporate and if this happens, there’s no way to get them back. If you want to moisten your buds before curing them, you can spray a bit of water, this will allow the flowers to absorb the moisture and go back to normal.

Leave space between the hanging branches, especially in high humidity.

If you’re not able to control the drying conditions, make sure you leave space between the branches, especially if you didn’t trim your flowers before hanging them, this will prevent your buds from getting mold by allowing air to flow in between them.

11. What To Do Right After The Buds Are Dry?

Once the 15 days have passed (if everything goes as it should), you should quickly transfer all of the buds to an airtight glass jar because you don’t want your flowers to continue drying.


How to dry cannabis: dry buds

The best way to cure weed is to place your dry weed in an airtight glass jar to cure your cannabis for around 2 weeks.

When you’re 100% you have dried the flowers properly, transfer them to a glass jar with a boveda pack if possible and let the curing process begin.

12. Curing Your Dried Cannabis Flowers

Ok, so you have made it through the 15-day drying period, and you are ready to smoke up some of those delicious homegrown nuggets. And sure, who are we to tell you to wait any longer? But, if you really want to get the best out of all that hard work, you 100% need to wait a bit longer. Their general consensus these days is that cultivating the crop is really only about half the work, with the drying and curing process being much more important than once thought. The old saying ”good things come to those who wait” could not be more true than when it comes to curing your precious buds.

What Exactly is Cannabis Curing, and Why do We do it?

It's pretty simple really. Curing cannabis is the weeks to months-long process of slowly but surely removing all of the tiny amounts of moisture still left in the bud after the drying process is finished. This is done under controlled environmental conditions, and when it is done properly it allows the terpenes and flavonoids to mature correctly and fully. When cured correctly, the process can turn undesirable, rough on the throat flower into a bud that offers a deliciously smooth and nuanced smoke.

What Is CBN?

The floor and aroma profile is not the only factor that goes through a metamorphosis during curing. The improvement in smokeability also comes from the degradation of sugars and chlorophyll, and over time THC will turn into CBN - a less psychoactive cannabinoid that aids in sleep, pain relief, and offers some neuroprotective properties not found in THC or CBD. Curing your buds will also greatly increase their shelf life, and reduce the chances of any mold issues. Properly cured and stored weed can last more than a year without the flavors, aromas, or strength being negatively affected.

Factors to Consider When Curing Cannabis

There are a couple of important factors to keep in mind when you are getting ready to cure your weed. These factors can be the make or break between curing success and failure, so pay close attention to these during the entire curing process.

  • Keep a close eye on the humidity levels - First thing to remember is you can not start the curing process until the buds have dried to the correct level. If the weed still has too much moisture trapped inside, mold will develop and ruin everything. If you smell any hints of ammonia when opening your curing jars, get them out immediately and back into the drying room. You also do not want bud that has been dried too quickly, as this will create a horrible smoking experience. The correct humidity levels for drying are 45 to 55%, with curing being a little higher at more like 60 to 65%.


  • Keep it cool, but not too cool - The perfect curing temperature sits at about 21C or 70F. Higher temps will lead to the breakdown of terpenes and cannabinoids at an accelerated rate, which can lead to a reduction in potency and flavor.


  • Cure your weed in the dark - Sunlight (or artificial light) is what we try to get the most of during the cultivation process, it is what allows the plant to produce those gorgeous, glistening trichomes containing all of the terpene and cannabinoid goodness we love.


But, as soon as you cut your crop it needs to be kept in the dark as much as possible. Light leads to cannabinoid and terpene deterioration, which is the exact opposite of what we are trying to achieve with curing.

The Curing Process Explained

Curing cannabis is a simple, straightforward process that does not require any previous experience or special knowledge, just dedication, a hint of self-control, and a bunch of patience. Once the buds have been trimmed, it's time to start the curing process. Place them into an airtight container. The airtight part is important, so we usually suggest going for a sealable mason jar or the rubber sealing ring. Carefully place the nugs inside without squishing them, and do not fill the jar further than about 75%. Air exchange is the most important part of curing, so make sure there is enough room for the weed to “breath”. Give the whole jar a little shake - if the buds clump or stick together then they are still in need of more drying time. For the first week or so it is important to check how the process is proceeding a minimum of twice a day. There is a chance that you may see very slight signs of condensation on the inside of the jar.


How to dry cannabis: what to consider

Flowers can get too dry, in this case, you can spray them with water to increase the moisture in them.

If this is the case get the bud out and let it dry for a few more days. If everything is going smoothly, leave the jar open for a minute or so each time you check on it. This allows for the fresh air exchange that is so important to the curing process. If you have a hygrometer (if you don’t, get one) then check the humidity percentage. If it is reading 70% or higher, leave the jar open for a few hours to allow this level to drop back down to the desired 60 - 65%. If it's lower than expected, burp the jars less often. Continue with this twice daily burning routine for the next 10 to 14 days, then reduce it to once a day for the next week after that. Once you hit the three-week mark you can consider your weed to be cured, but for the best results, you will need to continue this process of twice-weekly burps for the next 5 to 6 months. It’s only at this point that your weed will reach its true peak.

13. In Conclusion

There's no such thing as a weed dryer, if you follow the right steps and have plenty of patience it will only take 2 weeks to have cup-winning flowers. There are many ways during this time things can go wrong, so take the extra steps necessary to turn the crop you have spent the last 10 weeks growing into the finest cured flowers around. Also, have in mind that the curing stage can also affect how your buds taste and smell, despite no being a best way to cure cannabis, the glass jar method works great so you should always leave them for at least 2 weeks in a glass airtight jar for the best results. There isn't a quick way to dry weed, it’s not worth ruining your harvest in the very end so make sure you do everything as you should, if you have tips or tricks to help fellow growers dry their flowers properly, please leave a comment in the comment section below!
