Ahoy
@Nine Toed Hippie,
FYI 2019 was presented as a drought year locally for my purposes.
I am coaxing some not so fresh Purple Urkle presently, so this is what I am doing.
(1) For the seed bath I am using half salic acid (SA) 60 mg/diluted as a rooting booster and half American Sycamore Brass for it's high Abscisic Acid (ABA) content as a hull rejuvenator. 24 - 48 hours
(2) For the waterboard solution I will use straight willow brassinosteroid (Brass) from 2019.
(3) For the rehydration of my substrate prior to seed with tail planting I will use Mega Crop at 4 gram strength.
I will outline a similar but more involved procedure for you that will have you first introduce the oldies to some MethylJasmonate (MeJA) to jump start the germination sequencing in the hull.
edit; sorry forgot why drought year 2019 was good. American Sycamore trees when exposed to a drought produce collectable aba on the surface of it's foliar mass.
