Maybe one of our killer photo specialists could shoot some buds and water cure them for a week then show us the photos a week later? At least that way we can have a photo comparison as I don't think we have ever done that.

I'll do it but I am far from a decent photographer as I only have average macro. I was hoping Beamish could take some pics :)

Trichomes are still there (its called a magnifying glass). I feel the high is changed though, as flavinoids etc that are susceptible to water are gone. Its been proven that terpenes/flavinoids affect high. So know, you are messing with your high.
Firstly, how can some form of matter be "susceptible to water"? That sentence doesn't even make sense.

If you mean "soluble in water", then neither terpenes nor flavonoids are soluble in water. They are non-polar organic molecules, thus are only soluble in non-polar organic solvents. Water is a polar protic solvent, it will not dissolve terpenes or flavonoids.

Furthermore, flavonoids are absolutely not psychoactive compounds. They have no effect on the cannabis high. They are anti-oxidants.

Want to know the reason water curing "messes with your high"?

It's because water-cured buds have less cellulose, lignans and other forms of organic matter that pyrolyze to toxic aromatic hydrocarbons when you smoke them. When you smoke water-cured buds, you're simply ingesting less benzene and other carcinogenic crap, and that changes the subjective nature of your high.

So apparently you just prefer high amounts of carcinogens in your smoke...

Again thank "Roger&Me" with the solid irrefutable scientific language to make this as clear as possible to the dim-witted.

I am about cut down some buds that i think are gonna be prime candidates for partial water cure.
MAYBE i could remember to take pics,
and then mail out little bits of before and after to everyone lol/jk
lets hope so for the pics.

I thought we all agreed that the aromatic properties are gone with water cure. (Plant terpenoids are used extensively for their aromatic qualities). No more smell=almos no terpenoids.

Studying the Effects of Terpenes

To the Society of Cannabis Clinicians:
Most interesting to me are the modulating effects of the 120
Terpenoids found in Cannabis. Pure THC is pretty boring, flat, one dimensional with little individuality. Not sure I would be a Cannabis smoker if THC was all there was. But add a small amount of Terpenoids and the picture changes, some Terpenoids like Limonene make the subjective high much faster in onset and much stronger, with rushes, more clear, speedy, up, cerebral, euphoric, psychedelic. While other Terpenoids like Myrcene make the THC physical, mellow, sleepy, as well as stronger.
It has been obvious to me for more then 20 years that Terpenoids played a major role in modulating the effects of THC, but now for the first time I have proof. I did the work with a volcano, using liquid pads for putting the Cannabinoids/Terpenoids on, and used Cannabinoids that were 99%+ purity.
I tried pure THC, THCV, CBD, CBN, CBG, and CBC will be next, I have gram+ amounts of each. I have also tried a dozen pure Terpenoids with and without Cannabinoids. I used the Musty drug reaction scale before and after dosing as well as a better more specific one designed by myself for all of the tastes, smells and effects of the Terpenoid/Cannabinoid inter-reactions. I have 10 subjects so far doing the testing with me.
The bottom line is that all of the reported different effects of different varieties of Cannabis are reputed to be from the Cannabinoids. But besides the effects from THC and very occasional small amounts of CBD found in herbal Cannabis, all of the different reported subjective effects are in fact from the Terpenoids/THC. This has to be good news for proponents of herbal Cannabis over pure THC for medicine? I do not know if the Terpenoids are as active in modulating THC if the dose is oral by eating.

"Cannabidiol (CBD) possesses sedative properties, and clinical trials show it reduces the anxiety provoked by THC. Similarly, terpenoids in Cannabis also possess sedative properties when inhaled, such as linalool, citronellol, and a-terpineol. Terpenoids may also mitigate memory loss. THC causes cholinergic deficits in the hippocampus, which can be reversed by inhibiting acetylcholinesterase; this inhibition is provided by limonene, limonene oxide, a-terpinene, g-terpinene, terpinen-4-ol, carvacrol, l- and d-carvone, p-cymene, fenchone, pulegone, and 1,8-cineole.
Inhalation of 1,8-cineole increases cerebral blood flow and enhances cortical activity. Many aforementioned terpenoids, cannabinoids (CBD, cannabichromene, cannabigerol), and flavonoids (cannaflavins, apigenin, quercetin) have potent antiinflammatory activity or serve as neuroprotective antioxidants. These same compounds kill bacteria and fungi which may contaminate bacteria, they inhibit the growth of human carcinoma cells, and they serve other useful functions."

On an other thread here, the subject of curing buds faster has come up so I thought I would introduce the subject of water curing. The following is an extract from the now defunct Overgrow site. While, I myself have never cured using this technique, I have smoked water cured weed at a few occasions and I really liked it, the taste is so clean and smooth.

Introduction - What is the water cure? Why would I want to do it?

The water cure has only recently come to light as a widely accepted form of curing (mostly because of this thread). Water curing uses osmosis to flush out the chemicals, chlorophyl, pesticides, pests, and anything else you would rather not be smoking. The water cure is also very fast (about 7 days) with optimal quality (as compared to 30 days air curing), and as well does not stink like an air cure does. Water-cured buds are also more potent than air-cured (however there is proportional weight loss to potency increase).

THC is not water soluable, and the bud is protected from air/light, enabling potency to be maintained at it's highest levels, while the nasty chemicals are flushed out. Some growers report being able to add nutes all the way up to their harvest date because the water cure takes care of the built up chemicals.

Because of its speed, stealth and clean taste, water cure is very inviting to most non-commercial growers. The commercial grower might not be attracted to the water cure, as the weight of the bud is diminished.

Water cure can also be attractive to those smoking/cooking with suspect cannabis (schwag), moldy bud, pest infested bud, unflushed bud, etc.

How will my bud taste/smoke/smell/look?

Properly water-cured buds (submerged for 7 days and properly dried) will have a clean, thick taste when smoked, as well as being more potent than air-cured buds. This is one of the major advantages to the water cure; a quick drying process that retains potency and has a clean taste a flavor.

Smoking reports vary, however most people agree that water curing provides a very clean, smooth taste. Those with hashier, sandlewood/piney and harsher strains will find this method enjoyable for the clean, thick flavor without the edge (like a fine whisky).

However, those with frutier tasting strains have mixed results. They report the smoke is almost too smooth - much of the fruity/citrussy flavor removed.

The smell of the bud is greatly diminished, which many believe is one of the positive side-effects of water curing. Some also report a diminished smell in the smoke itself.

Water-cured buds tend to look more earthy and dark in tone. Some say the bag appeal is decreased, however proper care while water-curing can improve bag appeal.

What do I need for this? What is the process?

1. A container hold your bud and appropriate water (about 4 times as much water as amount of bud). A cooler with some kind of drainage works great.

2. A dehydrator or low-impact heat device. Dehydrators work great and cost about $40 from walmart. Radiators work well (as long as it isn't too hot), and some report using hair dryers.

3. A cool, dark place to put the water-curing container.

You need at least 7 days to do this, any less than seven can result in undesireable quality. Even 5 days in water is not enough - you need seven!!!

Plop in your freshy cut buds (or schwag, whatever, but fresh buds work best) into enough water to completely submerge the buds. The buds will float to the top for the first few days of this, so you need something to hold them down (a block of wood, a plate, etc). Change the water every day for 7 days, any less than seven could result in undesirable results (trust me). Try not to disturb the buds when changing the water as plant material can break off more easily (read: trichomes). Always keep the lid of the cooler open, do not seal off the container.

The water may take on a yellowish/greenish (even brownish) tint each day, moreso as the bud becomes completely saturated with the water. It will probably also stink. This is good, as it is the nasty chlorophyl and salts exiting your plant.

After 7 days remove the buds from the water. They will be sopping wet, and can be dried relatively quickly. MPD (and many more of us) purchased a food dehydrator from wal-mart for about $40 and consensus tells us this may be the best method for drying. Put the dehydrator on the lowest setting and dry for about 5 hours or so.

Radiators and other low-impact heating devices can also be used. Users have reported hair dryers working with some success, as well as hanging the wet buds on a clothes line with a fan circulating air. The important thing to do is to ensure the buds dry quickly enough to not become moldy, but with as low-impact of a drying environment as possible.

7 DO'S and DON'TS of water curing

1. Do not close the lid on the cooler. As the chlorophyll bleeds off into the water it evaporates - this is good and sealing the cooler just puts the crap back in the water.

2. Keep out of direct sunlight. I just put the cooler in the garage and that's the end of that.

3. Don't stir or agitate. This serves no useful purpose.

4. Don't bother straining the water for trichomes when you change it each day. I've tried it countless times and have yet to get enough trichones to make it worth the effort, though some hairs will break loose.

5. I've water cured as long as 9 days, but there was no real improvement over the 7 day mark - so why bother?

6. Do use a dehydrator. They cost $35 over at Walmart and you set it on the lowest possible setting. Mine takes about 5 hours to dry out a 1/2 pound of sopping wet buds. If you line dry make sure there is a drip tray or tarp for them to drip on.

7. DO NOT water cure seeded buds that were intentionally seeded so you can harvest seeds. Air cure these buds only...

What is the dry-weight ratio comparison with air curing?

Dry weight using air cure usually returns about 25% of the freshly cut bud weight. That means if you had 10 grams of freshly cut plant, you would get about 2.5 grams dry.

Water cure, on the other hand, returns about 15% from wet to dry. In our 10 gram example, that would be about 1.5 grams.

So why is there less weight using water, but more potency?

THC is not water soluable. When the buds are underwater, they are protected from environmental conditions such as humidity, over exposure to air, temperature, and light. This consistent state is something not easily achieved through the traditional air cure, which can be prone to a harsher smoke with decreased potency if everything isn't just so.

Water cure enables the removal of undesireable elements from your bud while retaining potency.

How potency is increased through the water cure

I should explain this so that the conspiracy theory kooks don't land on me like a ton of bricks.

Here's the "magic" behind the increased potency you get by water curing.

For the sake of making it simple, I'll use an example of 100 grams of bud going into the pot.

Now, you had this bud assayed and know that 15% of it is pure THC.

15% of 100 grams is 15 grams. So in our example the 100 grams of fresh bud has 15 grams of THC in it.

You water cure it and dry it. Now you have only 70 grams of bud left. WTF?

But you are deceived because the 15 grams of THC is part of the remaining 70 grams of bud. 15 divided by 70 equals 21.42%.


The mass didn't change, just some of the things that were there - aren't there anymore, so what is left becomes a bigger proportion of the entirety.

You go assay your water cured bud and find out it has 21.42% THC content - a 50% increase in potency.

Not bad, eh?

How osmosis leaches nasties, saves trichs

In air, chlorophyll breaks down at a rate that is only slightly faster than the breakdown rate of the resin - hence the reason the pot is dried for a short time then placed in jars and burped - but always out of direct sunlight because sunlight plus air equals an ideal situation for the THC is to break down and thus a loss of potency may ensue.

In water, the chlorophyll breaks down (out of the plant) while the THC remains suspended in the resin and is relatively unaffected by the surrounding water medium.

More on chrlorophyll removal

Water curing and air curing are doing exactly the same thing except you retain flavour and smell with air drying and with water curing you lose that flavour and smell but you have a smoothe smoke....

The Chloryphyll in the plant leaves through either the water evaporating (air cure) or through osmosis into the water around it...Water curing is obvously more affective at removing chloryphyll because you are adding more water, and
the smoke is smoother (chloryphyll is a big factor in bad tasting and bad burning weed)....however smell and taste come from terpenes in the plant that are also water soluble so they are lost in the water curing process....

In air curing the chloryphyll has to leave by the evaporating water in the bud....this is less affective but you keep those smell and taste terpenes.....so why after going through the trouble to preserve and develop them through air curing would you dunk them in water and lose them?

Its either one or the other

When you wash your weed your inprove its quality.. i have smoked many times by washi

No.I have smoked weed after washing it's much better to wash it and smoke it gives better taste n u can Suck the smoke better once we had washed the weed soo much that it felt like sugar try it n u wil never be dissappointed .. But make sure after washing dry it a bit so it can burn otherwise you will have to use ur lighter all the time. Dry it by a cloth.. Put the weed and press the cloth
