Yes you can speed dry the plant material, but it will volatize more of the turpeens and accelerate decarboxylation rates more than a standard cure.

I will post a decarboxylation graph that shows decarboxylation and THC conversion to CBN are very close to the same low rate at temperatures under 176F.

The latest research that I've seen pushes aside many old assumptions, including some that I personally held, and proffers that both THC and CBD both come from the same CBG precursor and it happens exclusively in the trichomes.

You can never get all the trichomes using dry sieve or bubble techniques, without beating so much green plant material into it, as to make it harsh and unpalatable by conventional standards.

Solvents will remove most of it, without doing so and is how we process large amounts of material to supply oil to cancer and terminal patients attempting a gram a day for 60 to 120 day cures.

If your heart is set on hash, we typically dry and freeze the material that we wish to harvest intact trichomes from and run it through our home made vibratory sieving unit, for 3 to 5 minutes, until it removes approximately 10% trichomes by weight, and then extract the remaining cannabinoid resins using butane or ethanol.

We also make oil or glycerin tincture using the partially spent material.

For bubble hash, we also freeze it to -32C/0F and pre chill the ice bath before a 20 minute run in a mini washing machine.

Almost all of our extraction is from cured material, but you don't have to dry your material to remove the trichomes by dry sieving or ice water extraction, if you freeze it first and keep it that way during processing.

The same is true for using a non polar solvent, as long as you also keep the solvent at low temperature also.
