At 9:23 he mentioned a hyperspectral sensor which is really just a continuous band in contrast from multispectral which is discrete ideally non-overlapping RGB, RE and NIR mostly for hyperspectral from UV,VIS up to NIR (thats like from Blue to Near Infrared) agreed you can and its a huge file size too (could be like 200 slices of imagery in one shot) - the burden would be on the data processing.Its the same what you get from satellites that have spectroradiometers, which you can also do with a portable equipment on the field or just carry around a USB spectrometer with a fiber probe to giet the spectral signature of the plant - these can be expensive ground truth measurement instruments.

At 20:31 comment satellite imagery is and can be high resolutions if they are purchased from commercial companies examples of these can be WorldView2, RedEye, Quickbird etc. no drone sensor can beat the number of bands of these satellites and its sensitivity even the USGS free Landsat 7/8 still on mission has already 8 and 11 bands respectively other commercial satellite imagery can have more and more precise cut certain bands say in the NIR and have an even higher resolution panchromatic band that you can use to interpolate with lower bands from RGB for example
