Actually, in a shallow pan it only takes all day.
And does pick up water from the air.

A rice cooker will speed it up, but you still need to use a fan.
Ethanol vapor burns with an almost invisible flame.
And with the right vapor to air ratio, is explosive.
I only do it out doors, with a fan, and use an induction heater for the boil.

My rig re-condenses the ethanol for re-use.

So the vapor is mostly contained
I still use the fan though, because Murphy lurks.
Might not see vapor leaking until half past ignition.

And, that stuff is too expensive to just boil or burn off, yah?

"Some people have mentioned the everclear takes longer to remove the trichomes?"

I did not find that to be the case.
I inspect the buds with my Eyeclops 100X 'scope before and after the soak
3 minutes will work fine if you shake the jar well, and for maximum yield you could do 5 minutes without picking up to much chlorophyll.
Best to stick with 3 minutes and do two rinses though.
Because as soon as the temperature goes north of freezing your amber oil will turn fluorescent green and taste quite nasty.

If you leave the spent buds in the filter paper at the end for can watch the green color appear as they warm up.


Weigh the buds before you start, then weigh the oil.
I have ended with 21% yield, but it was superior bud to start with.
