Body of Abstract: Indoor farming offers the opportunity to achieve high crop yield and quality with precise genetics and environmental conditions. Light is of particular interest given its tight control of plant growth and development. The usage of LEDs (light emitting-diodes) indoors may ultimately allow optimizing light settings according to specific crops, plant developmental stages, and target traits. A main barrier for indoor farms is to implement such opportunities at a large scale. We present a small scale experimental setup that uses in vitro plants to allow for a rapid screening of effects of light on root and shoot growth, using strawberry (Fragaria ananassa) as a model. We tested two types of growth media: a clear media, typically used in laboratory settings, and a dark media, simulating large scale production with substrate. We observed differential root growth in the two types of media upon exposure to different light conditions. Blue light (450 nm) sensing by shoots and by roots promoted and inhibited root growth, respectively. Similar observations have been reported in Arabidopsis. Amber light (590 nm) led to opposite results. This setup is useful for rapid screening of effects of light on target crops for indoor farms. The system can be optimized according to the type of production system used.
