I searched around but didn't see anything so apologies if there is already something on this.
Do you think dissolved spice in IPA would clog up a spray nozzle? If not, what about laying out herbs in a single layer, dissolving spice in the alcohol and then spritzing the herb with it? Seems like it might create a really even coating of active ingredients.
You'd probably need to use a small sprayer but it might be worth it?
There's some fumarate lying around but I'm not sure if it'll end up FB. If anyone is able to try it, it might be worth a shot
