Water Curing Your Weed

Water curing is a superb method to prepare your buds for a smooth and satisfying smoke. This technique works to remove unwanted substances from within the flowers that lead to harsh, unpleasant flavours.

Curing cannabis buds is an essential part of the post-harvest process. Doing so will ensure that none of the growing time went to waste, and that your bud tastes as good as it possibly can. Harvesting may seem like the last part of the growing process, but drying and curing weed is paramount to prevent mould from occurring, and to remove any residue from within the flowers that leads to harsh tastes and an overall less-pleasurable smoking experience.

Traditionally, the curing process occurs after the drying process and involves the storage of dried flowers within jars. This is done to ripen the buds, allowing them to break down residual sugars and salts that lead to those undesirable tastes when lit up. Although this process is tried, tested, and effective, there is a method that is both faster and more thorough.

Water curing occurs before the drying process, and is extremely effective at flushing out and removing a wider array of lingering and unwanted substances. Water plays somewhat of a purifying role over the entire growing process. This clear lifesource can be used in the final weeks prior to harvest to flush out impurities and to enhance taste. And it also plays a critical role during curing to help to finalise this process.


Water curing utilises jars, much like traditional curing. However, instead of being full of air, they are full of water instead. Buds are placed inside the water-filled jars and left submerged for about a week.

During traditional “air curing”, the buds are left for a longer period of time to break down residual substances. With water curing, the presence of water helps to accelerate and augment this process. Water-soluble substances within the flowers such as sugars, salts, insecticides, and chlorophyll diffuse into the water. This process is more effective than the buds digesting their own sugars.

But what about the important substances in this equation, such as THC? Well, cannabinoids are fat-soluble, meaning that water alone isn’t enough to dislodge them from their trichome abodes and rid them from the buds. This means that water curing effectively removes any nasty remnants from the buds, without reducing their potency. This process works via diffusion, the movement of substances from an area of high concentration to an area of low concentration through a cell membrane.

Although water curing can successfully remove unwanted substances, there are other water-soluble compounds within the buds that may also be washed out too. This may unfortunately reduce the desired flavours and scents of a particular strain. However, this tradeoff is definitely worth it when it comes to avoiding overly harsh smoke.


Before beginning the water curing process, you’ll need to obtain fresh water and a decent-sized jar. Distilled water is preferable, as it is free of any potential contamination.

Next, take your harvest and begin to clean up your flowers by trimming off the leaves and stems. These can be kept to create hash later on down the line. Now, take your manicured buds and place them within your jar. Pour your distilled water into the jar until it’s full. The flowers will float to the surface, so it’s important to keep the jar full and the buds submerged.

Be sure to change the water every day to remove the flushed substances. Clear, clean water will work better to absorb residue than more saturated water. Water curing can take between 5–8 days to complete.

After the water curing period has ended, be sure to properly dry your buds so no mould has a chance to set in. The end result is bud that is extremely smooth to smoke, with a discreet scent.

Water curing is a highly effective method for removing residual substances from buds after harvest, creating a smooth and silky smoke.

What is water curing?

Original article published here.

When you harvest your weed, the buds still have all sorts of nastiness in them. Stuff like nutrients and sugars. If you grow organic, in theory, none of this should actually be bad for you, as far as I know. But, it tastes nasty. You definitely want to get rid of this stuff.

The “classic” way of curing is dry your bud very slowly. If you keep it in a cool, dark, humid place, the plant will continue to digest the sugars and nutrients. As well, some sugars with break down over time. Give it a week or two and it’ll gobble up most of what’s left, leaving you with good tasting weed. The classic curing method has a number of downsides, including a propensity towards mold. Methods like jar curing and bag curing are tweaks on classic curing, aiming to reduce the risk of mold and increase the amount of nutrients and sugars digested.

Water curing is a totally different method.

Instead of relying on the plant to digest the remaining nutes, you use water to dissolve them. If take some weed and soak it in a bunch of water. Nutrients are basically salts, and sugars are sugar. Sugar and salt dissolve well in water. THC and the resin glands don’t dissolve in water. Water works faster than digestion, so water curing is a great way to cure in a rush.

Normally, you water cure in sealed jars. Take a glass jar, like the kind you use for jar curing. Fill it with water and bud then close it tight. Change the water once a day for 3-5 days then strain out the water. Dry in a typical fashion (being extra careful about mold, since any lingering water droplets can increase the chance of contamination). That’s it! It takes 5 to 8 days, which is a lot better than the 10 to 18 days normal curing takes.

This method leaves your bud with very little taste or smell. It tastes flat, not even grassy. The smoke has very little smell and is not discernibly marijuana. And, it’s smoootthhhh. Like Belvedere vodka…little flavor so you can have some at lunch and no one will notice.

I have a tweak to this method. Instead of soaking it a sealed jar, I suggested using running water. My idea is that a continuous stream of water will cure faster. It works on the same principal as defrosting food, convection ovens, and even airflow in a grow room. Think of it this way; when you change the water at the end of the day, that water is pretty saturated. Saturated water doesn’t absorb new minerals as well as clean water does. When you have a convection current, you’re guaranteeing clean water all the time. This is why you want a running fan in your grow room, instead of just airing it out once a day.

To do this method, I filled a large bowl with bud and ran water over it. I used a very thin stream, so it was a small trickle of water coming in. The water was cool, but not cold. You want it cold enough that it doesn’t wilt the leaves, but not so cold that it makes the trichomes brittle. And you need just the smallest trickle of water. Too fast and you’ll agitate the trichomes and some will fall off.

8 hours is all it needs, maybe 10 if your buds are very dense or large.
