///dry-ice///

seems to me everyone is looking in the wrong direction for methods of drying and curing.

Dry-ice is frozen carbondioxide, or co2. co2 has no liquid state, it subliminates, changes from gas to solid or solid to gas. in the process of it evaporating it draws ALOT of moisture and whatever is in it.

so if you were to put said dry ice into some sort of cooler and lay a breatheable barrier between the precious colas and the dry-ice, you can sucessfully dry and cure your treasure in just a few hours. plus, if you have a continual grow op, you can siphon the co2 vapors out of the curing rig and gently heat it to room temp and recycle it into whatever plants need the extra ommmph that co2 provides.

but you should be warned that dry ice can cause severe burns due to its extremely cold nature. always wear gloves and proper safety attire when working with substances as such, and for the love of god try to be sober if attempting any of this.

be very carefull the buds dont touch the ice or get too close to it.

you can speed the process by mixing salt and rice together and burying the dry ice in the mixture with like a towel on top, but there has to be enough room for the ice to "breathe".

im open to all comments or critizism as long as its constructive.

Technically it does have a liquid state, but that only occurs when the pressure exceeds 5.1 atmospheres. Aside from that, it seems pretty plausible. Have you tried this before?
 
of course i have, the only problem with it is you gotta find a way to get it. usually around this time of year for halloween you can find it or you can order some meat from one of those mail order gourmet meat places, they like to pack the meat in styrofoam boxes with the dry ice. I cant really take full credit for the idea because i got it out of a grow guide, cant remember which one but it wasnt some one famous or anything. i just took the idea and improved on it. ive never actually grown my own i just help those that need an extra hand with theyre grows, but the experience has educated me enough to the point that im about ready to start a few plants.

The dry ice does work for the dry and the cure. the extreme cold breaks the starches, sugars and other icky stuff that the flushing might have missed and helps redistribute the little bit of moisture that is desireable in well cured buds. the only thing is how long you "freeze" them, if too long you can get freezer burn or overdried crumbly bud. Another thing is not leaving it in long enough and ventillation, YOU HAVE TO EXCHANGE THE AIR OR ELSE IT WILL JUST FREEZE THE BUD IN A "FRESH" UNDRIED/CURED STATE.

my next project is flash freezing clones, thawing them, then trying to get it to grow again. any opinions? im probly just gunna end up destroying perfectly good clones, but if i can figure it out, if it can be done, imagine what you could do....
 
quick note: DRY ICE CAN BURN YOUR SKIN, IT IS EXTREMELY COLD AND YOU SHOULD ONLY HANDLE IT WITH THE PROPER SAFETY PROCAUTIONS; WEAR GLOVES, EYE PRO AND FOR THE LOVE OF GOD BE SOBER. i dont need some idiot grabing the shit with his bare hands, and then getting flash frost bite and then have to get theyre hands amputated or some shit. its cold but you can handle it safely with like some thick leather gloves or oven mitts.

interesting theory. I wish I had some decent input, but I'm going to follow along to see the arguments.

The saying goes "It never hurts to try" but I know with animal cells the process of the ice crystalizing will damage the cells walls leading to necrosis and tissue death. I know that clones (and seedlings) are the most senstive state the plant will be in, so I'm thinking that you would have found a cruel, albeit creative, way to kill the little ones. I don't dry ice would work since it has to first cool the air surrounding the plant, then the plant itself; liquid nitro would almost immediately flash freeze the plant, but it would be extremely brittle. But hey, if you do go through with it try to post some pics of the process and results. Good luck.
 
After carefully reveiwing how baked i was when i came up with the idea, i really dont think it will work. but none the less ill see if a bag seed grower will let me try some experiments on his flock. i also have some ideas with hormones, but i think that would be best done in a more sterile environment
 
some states/provinces pose restrictions on dry ice, such as, how much you can buy, who can buy it, age requirements, ect. it just depends on where your at. i only suggested the steaks because theyre yummy. lolz

with what the dry ice or the flash freezing? ive done the dry ice and its my second favorite method of drying/curing . you dont have to do it to cure the bud, you can still use a preffered method of curing. I like it because you can do both in one process, alot faster then traditional methods. Alas some methods that take longer do yield better results, for example, my favorite method to dry is hanging the buds upside down in an attic with the sun and ventilation controlling temperature with a dehumidifier/humidifier controlling the humidity. Then use a mahogany humidor in a warm place (utility room with washer/dryer/hotwater heater) to cure the buds for no less then 16 days. But the dry ice is way faster and you can dry and cure at the same time. The results are comparable to any other method, the only reason its not my top favorite is for sentimental reasons.

im talking about trying to dry and cure with dry ice. I'd like to try that. It has the same results as normal methods?
 
Found this in the wiki book Marijuana cultivation - Michael Fread.




Dry Ice Drying

Because light, heat, and air all degrade potency someone came up with the idea of using a can or other container in a freezer or using a cooler to dry the marijuana using dry ice. Dry ice can be purchased at virtually any supermarket and is simply frozen carbon dioxide gas. In order to avoid injury you should avoid direct contact with your skin.

By using about the same amount of ice as marijuana you can dry your weed out without exposing it to air or light and certainly not heat! Simply lay down a layer of dry ice, put an insulating layer of breathable cloth over it like a cheesecloth or a simply kitchen towel. Then lay the buds spread out on top of the ice. Make sure there is a way for the gas to escape as the dry ice evaporates.

Dry ice never becomes liquid, it sublimates directly into a gas form and carries moisture away from your bud when it does. Once all the ice is evaporated your bud should be mostly dry. If not, put a little more ice in and repeat until it is dry.

Some experiments with this method have suggested that it may be better remove the marijuana before the ice is completely evaporated because condensation will collect in the container and add moisture back (although this moisture will dry more quickly since it is not locked in the cells of the plant).

What about doing it like a BBQ smoker???

Instead of having a firebox, you have a chunk of dry ice. Then where the exhaust would be, you have a computer fan drawing the cold, dry air through the drying chamber [what would be the cooking chamber on a BBQ smoker] to control the temp, simply regulate intake air at the "cold box" [just like controlling intake at a firebox on BBQ]. Just like on a BBQ smoker.

Probably I would consider a reverse flow, or offset design.
 
didnt know about the wiki. but it is right, to an extent. the amount of dry ice is proportional to the bud, but depending on what strain, or even grow methods. adjust the amount accordingly. experiment. see how much is more suitable to your needs, some times you will need more sometimes less, but all in all its a great way to speed the process and get those delicious buds in your lungs faster.

If the smoker is used then youll have buds that produce a smoky bbq taste, that i would imagine would go quite nicely with some ribs or pulled pork. lolz

the smoker is a good idea though, its already built to facillitate such an operation...

Actually I was thinking of building a cure box, based on the design of a smoker.

Some THC EVOO or Rub ... would simply melt off with the rest of the grease. Maybe in some finishing sauce might not be too bad.
 
dude i did this dry ice shit and its the shit!!! I dried and cured 1.23 lbs in like 36 hours with one of those coolers that you plug in with the fan inside. tryin to figure out how i can harvest all that precious co2 for my other ladies.
