THE PRODUCT LAYER
5 promoted findingsBest evidence, with the sources left in.
A compact reading set from the notebook and primary papers. Numbers stay attached to their study conditions; nothing here is a universal recipe.
Almost 2× total acidic phytocannabinoid concentration at 15 mM MeJA in one female hemp genotype.
Welling et al. · 2023
The same study reported concentration-linked reductions in height and above-ground biomass; n=3 clones per treatment.
+15.6% inflorescence CBDA at 0.1 mM; at 10 mM, inflorescence CBDA fell 22.61% and THCA fell 17.62%.
Garrido et al. · 2022
One medical-cannabis variety. Trichome density did not differ significantly, and leaf CBDA is not flower yield.
Among tested conditions, 100 μM was reported as best-performing for selected cannabinoid and glandular-trichome endpoints.
Hahm et al. · 2024
One hemp cultivar in one vertical-farming system; plant height and leaf area declined at higher conditions.
At mature inflorescences 6 days after treatment, 10 mM MeJA was reported to increase CBDA 78.4% and terpenes 94.7%, alongside other chemical endpoints.
Testone et al. · 2025
One field cultivar and setting; these are concentration/assay changes, not proven total harvest yield or profit.
Trichome density increased under some treatments without a significant CBD or THC concentration increase.
Da Cunha Leme Filho et al. · 2025
More trichomes and more cannabinoids are separate claims; factorial treatments should not be collapsed into one number.
More trichomes.
A different question.
One 2025 study reported increased trichome density without significant changes in CBD or THC concentration. Structure and chemistry are separate measurements.

Hormones changed protein profiles without coordinated increases in cannabinoid content and related biosynthetic proteins.
Dimopoulos et al.Cells · Full-text summary
A field study connected developmental stage, transcriptomic responses and secondary-metabolite measurements. Responses depended on experimental context.

Investigates jasmonate signaling in the context of salinity, germination and early vegetative development.
Kasprowiak et al.Whole plants · Abstract only
Image analysis and gene-expression research connected jasmonate signaling with glandular trichome development and a candidate regulatory role for CsMYC4.
Huang et al.Molecular · Abstract only
The study measured glandular trichomes, chemical composition and plant growth together, reporting endpoint-dependent responses.
Hahm et al.Whole plants · Full-text summary
Inflorescence chemistry changed alongside broader metabolic and growth responses. Increased concentration and reduced biomass occurred within the same experiment.

Characterizes the cannabis lipoxygenase gene family and expression differences across tissues, informing oxylipin pathway research.
Fayaz et al.Molecular · Abstract only
Responses differed between tissues and treatment conditions. Some chemical endpoints increased while others decreased; trichome density did not differ significantly.

Examines genetic regulation and chemical development in female cannabis flowers.
Apicella et al.Whole plants · Abstract only
Reported changes in lignin composition and hormone content in young hemp hypocotyls.
