Light and Agriculture

Indoor Agriculture has been increasingly gaining interest as a means for plant assisted growth using artificial light. This has ramifications for supplemental food production during winter months, especially in regions with short days and reduced sunlight. This technology also has the commercial potential for ornamental plants as well and even perhaps for growing plants 24 hours / day.


UPRtek PAR Meter is designed especially for plant growth application, it is using PAR (photo synthetically active radiation) that plants assisted growth with artificial light, and provides PPFD (Photosynthetic Photo Flux Density) measurement unit to help us to discover the research for plants grow and build up the plant growth system.

Photosynthesis and plant growth

Photosynthesis

Plants use Sunlight, Carbon Dioxide and Water to make sugars used to fuel the plant's activities (e.g. growth, germination) - this is called Photosynthesis. This process can be simplified into 2 steps - Light Reactions and the Calvin Cycle (sometimes called Photo system II & Photo system I).

Plants Growth

Notes :
Photosystems are functional and structural units of protein complexes involved in photosynthesis that together carry out the primary photochemistry of photosynthesis: the absorption of light and the transfer of energy and electrons. Photosystems are found in the thylakoid membranes of plants, algae and cyanobacteria (in plants and algae these are located in the chloroplasts), or in the cytoplasmic membrane of photosynthetic bacteria. There are two kinds of photosystems: II and I, respectively.

Indoor Agriculture

It seems that the plant growth and light are inseparable, and since the light is so important to the growth of the plant. You cannot just check PPFD (Photon Photon flux density), you also need to know the characteristics of the light through the spectrum, check the LUX of the light, and even process a continuous measurement for a period to monitor the plant growth effectively... and so on. UPRtek PAR Meter can help you to accomplish all of them.

    The plant growth's success formula - PPFD (photosynthetic photon flux density) What is PPFD? It means how many photons hit a defined area in one second. PPFD is the unit of measure, defined by μmol/m2/s or micro-moles of photons falling on a square meter per second. Plant has various species and different categories which have different PPFD requirements. Normally, Photosynthetically available Radiation (PAR) wavelength is 400nm - 700nm. The light intensity has valuable effects on the plant due to the different wavelengths.
