Regarding Dry Ice Method..

Is it something to do with the dry ice that helps extraction or could the dry ice be replaced with say small rocks?

I ask because in the UK dry ice is very hard to come by and rather expensive at that

Ya it freezes the tricomes so they fall off ez. You can use normal ice if you can put the material in the freezer for a bit

People use dry ice because its really really cold. Small rocks aren't all that cold. Its pretty easy to find dry ice in the UK though and pretty cheap as well - ~1.3euro/lb. Call around... If you live in the boonies check ice cream makers.

just dry your herb out bone dry and use your extraction bags in the same manner you would with dry ice, to get dry sieve style kief. Same exact product, no need for the dry ice

The dry ice helps quite a bit.

I wouldn't waste my time kiefing if you have access to dry ice OP. Much better yields

yeah no doubt it helps quite a bit. He was saying it's pricey and was trying to find a way around using it. You won't get more resin glands off of the plant using dry ice, they will just come off faster.

For the curious-

Dry ice is actually frozen Carbon Dioxide (CO2). It is approx 109.3 degrees below zero, cold enough to flash freeze your skin and give bad forstbite burns. CO2 when frozen dissolves (or sublimates) as a GAS not a liquid, so it does not add any water to the kief or bud as you sift. It also flash freezes the trichomes off leaves, trim or bud. Regular water based ice cubes will never be as cold as dry ice and dry ice is *not* expensive if you live near a populated area. Notice I didn't say 'civilized'. Dry sifting is one way easy to collect some kief, but it cannot compete with dry ice period, in terms of quality OR quantity.

nice write up, But using dry ice isn't going to put more resin on the plant, nor will it make the resin more potent. i don't know what gave you that idea. Dry sieve hash is not easy to make if you're going for top quality. I've made plenty dry sieve hash that melted right through a screen, just like i've made dry ice hash that did the same. Dry ice hash comes out exactly like dry sieve. It's just much quicker with dry ice.

This isn't about putting more trichs on your material...if you have good ganja it's about getting the most trichs off!
Apparently you have not made that much Dry Ice Kief with quality bags. Anyone who has *knows* that dry ice wins hands down. Why?

1. 109.3 degrees below zero freezes anything... in a matter of seconds. This works even on large dense nugs (which could be bone dry or harvest day fresh) and still extract a larger yield. Dry sieving simply doesn't work on fresh trim or buds, sorry.
2. Dry ice *pulverizes* or breaks down leaf, bud and even stems due the extreme brittleness of the now frozen material. Dry sieving doesn't do that, even with a tumbler, which is old school and slow as hell.
3. Trichomes are sticky by design. Get them to 109.3 degrees below zero and they solidify and are no longer as tacky. This helps keep the trichs from sticking to other materials as they break off and separate from the leaf, trim or bud they were attached to.
4. Dry sieving anything causes a static electricity buildup on dissimilar materials: Just agitating one ounce of dry buds in a quart Ziploc baggie and you can see it sticking to the plastic.
5. Using quality sift bags (like Boldt bags) will allow you to get the most out of your product when used properly.


I can go on, but you should get the point by now.

so you're saying you can't get all of the resin off of plant material using the dry sieve method? I've made plenty in my time and I don't intend to argue with you about it. You can get the same amount of resin with the dry sieve method period. I agree that it is faster with dry ice, but you can't argue that you don't get it all off with dry sieve, because that's just not true.

Not an argument at all. I'm just trying to say that thorougly *freezing* the sticky trichomes with the dry ice method works better because they are not so sticky and pass through the screen material better, not just faster. And yes I have seen dense thick buds that still has alot of trichs left in the core after dry sieving for quite awhile. With dry ice you don't *have* to break up anything...it does it for you. And as I also stated, you simply cannot dry sieve fresh trim OR buds that are dank...they stick to everything and to themselves. With that being said the Dry Ice is vastly superior.

yeah in my earlier post you can see that i suggested fully drying the plant material before dry sifting. Although i thought that would be a given to anyone with a shred of common sense. You're proving my point that all dry ice will do is speed up the process. you say that you still saw resin on buds "after dry sieving quite a while" Exactly my point, you gotta do it longer if you want to get it all off. and you also say "with dry ice you don't have to break down anything because it does it for you", the only benefit i see there is that it saves you time. None of these make dry ice hash "superior" as you say, the hash you make with dry ice won't test any higher in thc than dry sift, you won't be able to see a visual difference, there will be no difference in consistency or flavor, because you are only DRY SIEVING in a cold environment.

kbo

WTF! chill out or do you need somebody to say your right, great fantastic - help your ego does it?

What Mac guyver was trying to tell you is that due to low temps of dry ice you end up fracturing the bond much easier and ..... are you ready..... doesnt stick to any thing.

Keep screening away kbo and if you want to argue with somebody go back and try this tone with your girl!
