Episode notes
Brix Reflects Sugar And Mineral Diversity
- Higher Brix readings generally mean more complex sugars and a wider variety of trace minerals in the plant tissue.
- A refractometer measures overall refractive index, so many minerals together raise Brix more than a single mineral spike.
How To Read A Refractometer
- Use a refractometer to read Brix: place a crushed sample and read the black/white boundary on the scale.
- Note the fuzziness of the boundary: a fuzzier line indicates more varied trace minerals in the sample.
Complete Nutrition Beats Quick Fixes
- A complete plant diet raises and sustains Brix, while single-nutrient boosts give temporary spikes.
- Urea and similar quick fixes inflate appearance but produce weak, pest-susceptible plants.
