Other claims from this paper (15)
- Intervention effect Lettuce biomass rose 35–90% as light increased from 200 to 600 μmol m−2 s−1.
- Intervention effect Red mustard responded well to increased light, with a 35–90% range reported jointly with lettuce.
- Observation Other crops responded variably to increasing light.
- Intervention effect Leafy-green quality often deteriorated at higher light intensities.
- Intervention effect Determinate tomato fruit biomass increased 8–15% from 300 to 600 μmol m−2 s−1 light.
- Intervention effect Cucumber fruit biomass increased 8–15% from 300 to 600 μmol m−2 s−1 light.
- Association Tomato fruit number increased with biomass.
- Observation Cucumber fruit number decreased while individual fruits became heavier.
- Observation Individual cucumber fruits became heavier.
- Intervention effect Increasing temperature had variable effects on production.
- Intervention effect Herb regrowth often lagged at 25 °C.
- Observation The expected fresh food production ranking was lettuce, cucumber, radish, then tomato.
- Intervention effect Spread harvesting raised yield of three lettuce cultivars to about 400% of single harvesting.
- Intervention effect Spread harvesting raised spinach yield to about 400% of single harvesting.
- Intervention effect Increasing plant density increased fresh food production.
