How long to soak bud with hexane?

Alot of different methods on www, really only want to do one soak method.

It is relatively forgiving. I've soaked overnight and still gotten a nice extract.

So used 4 ounces of bud cut up, hexane soaked for 40 minutes. Used hotplate with a pot of oil for the heating. Modified a pressure cooker with a off set condensor and let rip. Washed with Ethanol. The best oil I have ever tasted, no cough, and a little dot just keeps smoking......

Hexane has health effects though, with repeated exposure. Ethyl acetate might be a good alternative, since you appear to have a source for various solvents. Pricey but if you recondense it you'd be okay.

I've used heptane, made a pretty extract but was a bitch to purge so ended up washing with etoh anyway...i would say your best off just using chilled etoh to begin with n cut the middle man part of the procedure...a good ethanol extract can stand side by side with any other solvent and it's nice to be able to say made with 100% food grade materials

Hexane is a Class II solvent, because our livers turn it into 2.5 Hexane Dione, which is a carcinogen. Always better to use a Class III like Ethanol or Pentane when possible.

What about ethyl acetate? It has the advantage of not mixing with water. You can use still moist material and the solvent won't be absorbed like it will with dry. It can only reach the surfaces where the trichs are.

i'd recommend doing rosin , these solvents are bad for your health.

We haven't tried ethyl acetate, but looking at the numbers it should work well, albeit expensive.

THCA is actually more soluble in polar than non-polar solvents anyway, because it's a carboxylic acid. THC itself is much more soluble in non-polars than THCA so if using butane or hexane it might pay to decarb the material first. And about the ethyl acetate, I don't know why it's so costly. Aside from that, it would be one of the most preferable. You'd need to recycle it to make it practical.
