I am interested in exploring the feasibility of cultivating Zinnia angustifolia under controlled indoor conditions. Considering that most zinnia species typically thrive in outdoor environments with ample sunlight, it is essential to assess whether the specific requirements of Z. angustifolia—particularly its light intensity, photoperiod, temperature, and soil composition—can be adequately met indoors. Has anyone implemented experimental indoor cultivation setups for this species or observed any notable phenotypic changes when grown under artificial lighting conditions?
In addition to basic environmental parameters, I would appreciate insights into whether modifications such as supplemental CO2 enrichment or altered watering schedules have been necessary for achieving optimal growth and flowering. Specifically, are there documented differences in flowering initiation or overall vigor when compared to traditional outdoor cultivation? Any detailed observations regarding adaptation period, disease susceptibility, and nutrient uptake efficiencies in an indoor setting would be extremely helpful for further discussion and potential application in controlled environment agriculture.
