Samenvatting

This graduation research thesis is written following the assignment conducted at the Own Greenscompany to write a protocol for the use of increased concentrations of CO2 for the production oftheir crops. As a result of writing that protocol, it was researched what these effects of increased CO2concentrations are on production, water-use efficiency and the taste of lettuce within verticalfarming and hydroponic cultivation. Literature research showed that it is generally known that a difference in concentration of CO2 has aneffect on the development of the plant, but that this can even differ greatly per variety within aspecies due to the difference in sensitivity to CO2.
