Other claims from this paper (9)
- Association Increasing light levels linearly increased biomass, at 0.26 g per mole of additional light.
- Association Increasing light levels linearly increased leaf area, at 32.5 cm2 per mole of additional light.
- Association Increasing light levels linearly increased the number of branches per plant and square meter, at 0.41 branches per mole of additional light.
- Intervention effect Crop WUE improved by 1.6-fold when comparing the lowest and highest light treatments.
- Intervention effect Crop evapotranspiration increased 1.8-fold with the increase in light intensity.
- Association Lighting increase was associated with a 35% reduction in evapotranspiration per unit of biomass.
- Association Leaf photosynthesis and WUE increased with light enhancement.
- Observation Supplemental lighting up to 52 mol m -2 d -1 did not saturate any crop response to light.
- Recommendation Supplemental lighting of this level can be economically viable for cannabis nurseries.
