Interesting none the less. I guess humans aren't the only species with an affinity towards the herb! Haha.

For you, perhaps.
For me, it's quite upsetting.
I have loverly ladies in my care and, super bugs, I don't need.
One maggot looks pretty much like another, so I've made a little creche in a glass jar.
Should be easier to I. D. the hatch.


Anyways I will throw an update in here as well on my current science experiment. I just got finished straining the water from the herbaceous dankness. The drained water was a brown color. Probably a little darker than a medium dark beer. Like a dark lager color. It wasent green like I expected but brown. But that could have to do with the weed that was used which was kind of a darker brown red hair lookin bud. There was actually two kinds and the other one was more lime green but the darker one probably overpowered the color of that.

Anyways the bud is now soaking in 190 proof at room temperature. I am going to wait to try the frozen method you described untill next time since this one was already underway and I wanted to try it just once.

I was wondering how long I need to let it sit untill I get most of the goodies. You say three minutes, twice, for the method where the bud and ethanol is below the freezing point of water.

Answered your own question ya did.
Any longer than that, and you pick up undesirables.
With good bud, I get yields of >20% by weight.
With good bubble, I can get >70%.

If you wish to make a product that is free of undesirables, (pesticides, bug poo, spores, etc.) it's best to use as short a soak as possible.
It's also worth knowing that the capitate glands have a shell that is a waxy material.
That material could well hold contaminants, that are not resin soluble.
After you get pure, amber colored oil, a re-freeze and cold filtering will remove much of the wax.

But what about room temperature, does that change anything?

Indeed it does!
Chemical reactions are all about temperature.

Because I've heard anything from a couple days, to a week, to a month. I know people do it in a day with heat in a crock pot or whatever. But if just at room temperature, how long would you think would be sufficient??
The long soak at room temps is not about getting the resin.
The resin extraction is maxed in 6 minutes.

The long soak is about decarbing.
It takes months at room temperatures.
Once the oil is purged and purified, you can do a controlled decarb @ 260 ℉ and it will take ~20 minutes.
Of course, you can decarb the weed in your oven before you start.

But, you need to use heat for purging the last of the solvent anyway, so . . .

Weezard Reviewed by Weezard on . Water wash before ethanol extraction of cannabis oil? There are many solvents used to make hash oil. Among them are butane, naptha, isopropyl alcohol, and ethanol alcohol, which is food grade drinking alcohol. This thread is concerning only the ethanol alcohol extraction of the essential oils (hash oil). The other toxic chemicals are not feasible for me and i don't care how many people say all the bad stuff is evaporated etc. I don't care and I will never use those chemicals as long as I live unless I learn a lot more about chemistry and have Rating: 5
