I am currently in the midst of doing an academic research entitled "An Experimental Quantitative Study on Crops' Growth on Natural vs Artificial Lighting (CEA)" where I compare the crop quality cultivated under natural sunlight vs artificial lighting in CEA.
As it is a quantitative type, I am having trouble in quantifying the results and what proper quantitative methodologies do I have to employ to make the research successful.
Follow-up question:
After identifying the qualities of the crop I want to measure, what instruments are required, appropriate graphs to be illustrated for this kind of topic, and what methods should be employed to "measure a crop's quality"?
Edit: Made it more specific
Light influence on crop quality is a common agricultural question, and you should use prior work in the community as an initial model for your experiment. For instance, a quick search turned up Photosynthesis under artificial light: the shift in primary and secondary metabolism (Darko et al, 2014), but I'm sure there are many others.
