However, as mentioned above, chlorophyll is not the only pigment that reads information from the light source! MYTH #1 - from the information above, we can derive the origin of the common misconception that only RED & BLUE light is necessary for photosynthesis because of the chlorophyll a and b. Nevertheless, plants can use most of the light within PAR region for photosynthesis due to the other pigments (e.g., carotenoids ), which can efficiently capture the light that is poorly absorbed by chlorophyll. Chlorophylls absorb light between λ400 and 700 nm, known as photosynthetically active radiation (PAR) or photosynthetic photon flux density (PPFD), with the main peaks of absorbance in the red (λ600–700 nm) and blue (λ400–500 nm) regions of the spectrum. Chlorophyll exists in two forms- chlorophyll a and chlorophyll b. Light serves as energy source for plant growth and development through photosynthesis, but through photoreceptors, light regulates some morphogenetic processes such as flowering, stomatal opening, leaf expansion, plant elongation and circadian clock.Ĭhlorophylls, along with carotenoids, are the most abundant photosynthetic pigments that drive photosynthesis in higher plants. Light characteristics that influence pant growth and development are commonly attributed to intensity, quality, uniformity, direction, polarization, coherence, and pattern of illumination. However, I will try to keep short and share some basics into this mysterious world)) So, to be honest, this is a quite broad and complex topic that requires thousands of pages to have a good understanding. Skip directly to the DIY instructions if irrelevant I will explain relevant terms and concepts necessary to have a broader understanding, as well as reveal the common myths and misconceptions about Grow LED Lighting *This will be a long but informative chapter describing the WHY behind this tutorial. However, the next Agricultural Revolution has to be based on collaborative effort, and I strongly believe that open-source & maker community is the right place to start!!! The indoor farming, urban agriculture, vertical farms - are still a new and emerging trends with a huge potential of being one of the many solutions to solve food scarcity and feed the future population. So, that's exactly what we try to tackle here)) but the main issue remains the high price! Light is the primary factor that determines the outcome of the crop, aka its value! There are many organizations that focus on horticulture lighting, leaders on the grow light market such as Philips, Illumitex, Valoya, SananBio, Osram, Samsugn etc. Modifying the light wavelength, photon flux (quantity of light), and photoperiod lets one to adjust biomass accumulation, flowering time, stem elongation, and nutritional quality Light is one of the most important factors for plant growth and development, regulating plants’ photosynthesis, metabolism, morphogenesis, gene expression, and other physiological responses. GIY system, as beautiful as it looks, had a few drawbacks that was limiting its feasibility on the real market. Official Brand Store, or diyledu-home.After my first tutorial about Grow It Yourself (GIY), where I share my experience in building an integrated smart growing system, I decided to dive deeper into plant science, and try to use my tech skills to come up with a solution on a more fundamental level Please write to us via our email box if you have any question about our poducts, we will reply you within 24 hours.
