A cultivar-specific programme for aroma, light, nutrient formulation and mechanical stimulation, centred on Italian Large Leaf basil.
In brief
A cultivar-specific programme for aroma, light, nutrient formulation and mechanical stimulation, centred on Italian Large Leaf basil.
## Why basil first
Basil fits the device geometry, has a relatively short cycle, is used directly in premium hospitality and has published hydroponic evidence linking controlled light to aroma volatiles and mechanical treatment to sensory/metabolic response. [R01] [R02]
## FlavoRotor starting condition
|
Variable | Initial protocol decision | Basis
| Cultivar | Italian Large Leaf | matches [R01]
| pH target | 5.9; operational band 5.8–6.0 | [R01] maintained pH 5.9; [R03] used pH 6.0
| EC | record the EC produced by the defined elemental recipe; do not invent an aroma EC optimum | [R01]/[R03] specify nutrient conditions; [R08] supplies separate cultivar-specific EC evidence
| EC screening after baseline | 0.9, 1.2 and 1.5 mS/cm with one fixed stock formulation | centres the screening around [R08] hydroponic basil range
| Light baseline | measured spectrum, PPFD, DLI and 16 h photoperiod initially | FlavoRotor baseline; all values measured before trial
| Rotation | single measured baseline schedule; no rotation claim during first repeatability cycles | engineering isolation
**Engineering note**
The pH value is a literature-matched operating condition, not a pH-for-aroma rule. EC treatments are experimental levels, not recommendations.
## BAS-LGT-001 — spectral treatment
Use matched DLI and environmental conditions while changing a predefined spectral component. Primary outcome: selected volatile compounds by GC–MS. Secondary outcomes: fresh/dry mass, colour and blinded aroma discrimination. [R01] provides the literature anchor, not the expected FlavoRotor result. [R01]
## BAS-MEC-001 — rotation/mechanical treatment
Compare rotating and matched static controls after engineering light and root-zone equivalence has been demonstrated. Primary outcome: a predefined volatile or sensory descriptor; secondary outcomes: morphology and biomass. [R02] [R21]
## BAS-NUT-001 — nutrient formulation
Use complete elemental formulations and tissue analysis. Do not alter one stock bottle and label the response “potassium sweetness”. Cultivar, total ionic strength and nitrogen form remain explicit. [R03] [R04] [R08]
