Right LED Array: Yuta and Jualiang
The following selection of LEDs was made by Yuta and Jialiang:
- Blue: 12 (440-450nm)
- Red: 12 (650-670nm)
- Far red: 12 (720-740nm)
- White: 72
The choice for the LEDs is explained as follows:
Two identical PCBs are used to place the intended number of LEDs.
Middle LED Array: Muneeb
The following selection of LEDs was made by Muneeb:
The choice for the LEDs is not explained. Presumably, a red/blue ratio of 3/1 is used. Some of the blue is obtained from the white LEDs, which also have a peak at wavelengths equivalent to blue.

Left LED Array: Marta Pozzi and Hayato Nakanishi
The following selection of LEDs was made by Marta and Hayato:
The choice for the LEDs is explained as follows:
Two types of PCBs were used to place the LEDs. The LED array consists of three type 1 and one type 2.
The following PCB was designed:
