Aranet AgriTech - The application of technology to produce more with less, supply fresher more nutritious foods, while making the farm process more efficient and kinder to the environment.

What is Controlled Environment Agriculture?

It’s an indoor, technology based approach to cultivating crops under optimal growing conditions, It encompasses not only ‘Agriculture within Green Houses’ but also ‘Vertical Farming’. It’s here that the world is now cultivating an ever increasing range of crops. The Aranet range of smart sensors help you monitor and manage the analytics of tracking the drivers of growth helping you optimizing production.

Key measurement sensors include…

UPRtek PG200N Spectral PAR Meter - Spectral PAR Meter for Monitoring Artificial Lighting in Controlled Environment Agricultural.

The PG200N Spectral PAR Meter is a lightweight, mobile device designed for monitoring light in horticulture settings. It’s basically a smart assistant for the next generation farmer! It’s also an ideal research tool for academics with the ability to record information with respect to light and how it effects the growth of vegetables and plants.

The growing indoor horticulture sector has resulted in a booming market for grow lights. Whether augmenting sunlight or using it as the main source of light energy, the practice and proper usage of grow lights will have a significant impact on the appearance, taste and shape of the vegetable, fruit or plant that you are growing. There is only one way to ensure the quality and quantity of light being received over a large indoor farming area and that is to measure it with a suitable light meter. The PG200N Spectral PAR Meter is designed specifically for this application to test grow lights with both spectral and quantitative measurements allowing growers and researchers a tool for getting the best understanding of growing plants with artificial light.

Units of measurement include PPFD (400nm…700nm)

The PPF measurement of PAR only counts the total amount of light photons present between 400-700nm. It does not differentiate between photons at different levels within this range.

Photosynthetic Photon Flux Density (PPFD) is the amount (also referred to as intensity) of PAR light that lands on a square meter each second. PPFD is measured in micromoles per square meter per second (μmol·m-2·s-1). In other words, PPFD is how much PPF is hitting each square meter of your crop at any given second. It is important to look at PPFD when planning your grow light installation. Adjusting your fixtures’ height and density will affect the PPFD at your crop canopy.

Many studies have shown that specific wavelengths/coloured light have different effects on the growth of different plants and at different times in their growth cycle, you can use these anomalies to improve the growth and thus efficiency of your growing process. This is why the PG200N Spectral PAR Meter allows you to split the different light groups so that you can monitor the benefits that different light combinations can bring to the growth cycle of the particular plants that you are cultivating.

These are the different light groups that you can monitor.

PPFD  -  This covers the PAR (Photosynthetic Active Radiation) range 400…700nm wavelength
PFD  -  Is an extended range that includes some UV and far red fields in the range 380…780nm 
PFD-UV  - This covers PFD in the UV field at 350…400nm wavelength
PFD-B  -  This covers PFD in the Blue field at 400…500nm wavelength
PFD-G  - This covers PFD in the Green field at 500…600nm wavelength
PFD-R  - This covers PFD in the Red field at 600…700nm wavelength
PFD-FR  - This covers PFD in the Far Red field at 700…780nm wavelength


For the grower, it’s important to make sure that the PPFD data you get from your grow light manufacturer is accurate. It’s also important to be able to accurately measure the light that’s falling on your complete growth canopy and here you have to consider factors such as distance from the light source, a number of measurements that account for the average, and the minimum/maximum plus spectral analysis. All possible with the UPRtek PG200N Spectral PAR Meter.
