Coloured LEDs Lighting For Food Growing

Lighting and particularly coloured lighting is a vital factor that contributes to plant growth inducing both photosynthesis, phototropism and photo-morphogenesis. Detailed experimental studies on the photobiology of plants have already shown the importance of creating proper lighting receipts for different species, growth and developmental stages in order to obtain a good plant productivity and nutritional quality formation. LEDs, nowadays, are a good tool for creating the proper lighting receipts composed by different narrow wavelength combined for specific plants. Small dimension, long operating lifetime, great efficiency, digitally controllable features and optically controllable performances are also useful aspects for plants’ lighting system development not only for laboratorial research experimentation, for aero-spatial and industrial food production but also in other field such as for educational and therapeutic scopes [1-2-3]. More than this, domestic food farming is currently an increasing trend derived by both the emergent interest in eating healthy, genuine, km-0 and origin controlled food combined with a raising necessity of nature reconciliation through sustainable behaviours and responsible choices [4]. In this regard, an LEDs lighting system for home farming can be a possible solution especially in particular domestic environment lacking natural lighting or good climatic conditions, with limited or absent natural spaces as gardens, terraces and balconies that can be used for farming.
