Why is my hash oil always very dark?

Every batch I make comes out dark green or brown.
I don't use butane ever, but try all the other solvents.
What is the trick?

Sadly for you, the secret is butane. BHO is just fucking good.

You are letting the solvent be in contact with the material too long.

Try a 15 second wash..

Not sure what process you are using, but heat darkens cannabis oil, as do contaminants.

How are you preparing the material, what alcohol are you using, how long are you soaking it, and how are you removing the alcohol?

I use alcohol and yesterday, I tried acetone for the first time. I normally put the trim in a jar, add the solvent, and shake for 30 seconds. Strain, and repeat with more solvent. I let it air dry in a flat pan.
With the alcohol, I get an oil that sticks to everything! The batch with the acetone looked just as green in the liquid form but once dried, was easy to roll in a sticky ball. The ball looks green, but not black!
Do you have any experience with naptha? I am not sure what the difference is.
From what I can tell, there is a lot of heated discussion over solvents and what is safe or not.
In my mind, acetone, mineral spirits and lacquer thinner are all the same!
I really appreciate your input!

You didn't say how you were preparing your material, but I suggest doing trim whole and lightly packed for QWISO.

30 seconds is pushing it. I would try 15 to 20.

Alcohol extract is sticky. I've never done acetone.

I have never used naptha (white gas) either, because it is hard to purge, but it a mix of hexane and heptane, both of which I have used.

Acetone, Mineral spirits, and lacquer thinner are different chemicals.

Hexane is a lot easier to remove than heptane or ostensibly naptha.

I usually use butane, hexane, ethanol, or isopropanol for oil extractions.

I also extract the concrete using one of the other solvents, and wash it in ethanol to clean it up into an absolute.

Jump 117 has published a couple tutorials on producing amber with alcohol that you might check out in this forum.

I used whole trim and ground up trim. I have read that it is better to grind it up and use a large screen to strain through. This last batch was ground up. I am doing small batches of 5 gms of trim at a time to test each solvent and trick! I will post my results when I am done for whatever it is worth.

I gotta say crushed/ground up flowers do not produce the same quality as whole buds. As an example, you will find it very difficult to get an oil of this quality with anything but whole, well-trimmed buds:




30 seconds (especially with vigorous shaking) is way too long for anything you actually want to smoke, imo. Maybe if you're cooking with it that would be alright. IMO the only way to get QWISO or other quick-washed extractions to be on the same level as BHO is by literally pouring the solvent over whole buds in a permanent coffee filter with no soaking or shaking whatsoever. After that first run of top quality you can chop the buds up or shake them for 5-10 seconds and then strain. Anything past 15 seconds when you're shaking it or 20-25 seconds if just sitting in the solvent is going to pull out chlorophyll and other nasties and leave you with black tar oil.

peace

Isn't there a lot of thc left in the buds/trim if you pour over it just once? Can you do anything with the material aftere a one time use?
