“…It has been suggested that, given its low energy consumption, LED technology could potentially be adopted in large-scale indoor farming [17], however, the feasibility of its use in small-scale indoor cultivation systems depended on the combined effect of several factors. The estimation of the energy input absorbed for each cycle gave quite a clear idea about how slight variation in the growing conditions (cycle length, photoperiod, light quality, and intensity) could impact on the final costs of the production, especially in small-scale systems, like those designed for indoor micro-growing.…”

Sustainability is the most critical point in micro-scale indoor crop systems. It can be improved through the optimization of all of the production factors, such as water, nutrients, and energy. The use of light-emitting diodes (LED) allows the fine regulation of the light intensity and light spectrum to be obtained, with a significant reduction in energy consumption. The objective of this study was the optimization of a LED-based protocol of light management for Romaine lettuce cultivation in a micro-growing environment specifically designed for home cultivation. Four different growing cycles were tested. In each one, the light spectrum was modified by increasing the percentage of red light and decreasing the blue light. This resulted in a change in the light intensity which ranged from 63.2 to 194.54 µmol m −2 s −1 . Moreover, the photoperiod was shortened to reduce the energy consumption and, in the last cycle, the effect of the daily alternation of dark and light was tested. The fresh and dry biomass produced were measured and the energy consumed in each cycle was monitored. The quality of lettuce was evaluated by measuring several physiological indexes, including chlorophyll a fluorescence, chlorophyll, sugars, nitrate, lipid peroxidation, carotenoids, and phenolic index. The results obtained showed that the productivity and the quality of lettuce can be positively affected by modulating the light quality and intensity, as well as other cultural practices. At the same time, the estimation of the electrical energy consumption indicated that little changes in the lighting recipe can significantly affect the energetic, environmental, and economic impact of home productions.

“…Interest in the use of LED lights and indoor cultivation systems is growing, as well as the concern about the environmental impact, the energy costs, and the quality of the produce that can be obtained [1,17]. It is generally thought that this kind of system cannot economically compete with traditional greenhouse cultivation.…”

Microalgae are photosynthetic microorganisms that use sunlight as an energy source, and convert water, carbon dioxide, and inorganic salts into algal biomass. The isolation and selection of microalgae, which allow one to obtain large amounts of biomass and valuable compounds, is a prerequisite for their successful industrial production. This work provides an overview of extremophile algae, where their ability to grow under harsh conditions and the corresponding accumulation of metabolites are addressed. Emphasis is placed on the high‐value products of some prominent algae. Moreover, the most recent applications of these microorganisms and their potential exploitation in the context of astrobiology are taken into account.

“…Nevertheless, algae, particularly microalgae, belong to a species that can be of great interest for vertical farming, e.g. for vertical agriculture in space [30], while the outdoor cultivation of temperature-tolerant algae such as Chlorella sorokiniana in column photobioreactors may also be a research objective aimed at sustainable food production [31]. Th is suggests that there is a broad area of research of possible new fi ndings and developments related to the growth of adherent algae on diverse textile fabrics with potential vertical farming applications.…”

Vertical farming is one of several ideas that are being developed further by diverse research groups, companies and private citizens. Due to the growing problems of urbanisation and a growing population, vertical farming has presented itself as one possibility to feed people, particularly in large and densely crowded cities, in an effi cient and eco-friendly way. Interestingly, while agrotextiles are often used in agriculture and textile fabrics can be bought, for example, as frames for small vertical farming solutions for private balconies, only a few researchers have studied the possibilities of using textile fabrics as substrates for vertical faming to date. This study provides an overview of possible future applications of textile fabrics in vertical farming solutions.
