Cutting-edge LED Dimming Systems to Maximize Greenhouse Profits with Dr Marc van Iersel of Candidus

Dr. Marc van Iersel explains the cutting-edge technology behind the Candidus adaptive LED dimming systems that help growers around the world often save more than 30% on supplemental lighting electricity costs to increase profits. Candidus systems utilize a variety of inputs such as individual crop DLI/photoperiod requirements, weather forecasting, current greenhouse environmental conditions, and real-time peak and off-peak electricity rates to precisely dim and brighten LED grow-lighting fixtures in controlled environment agriculture applications like greenhouses and vertical farms. Behind labor, supplemental lighting is the second biggest expense in most commercial greenhouse operations. Using a precision flex-dimming system instead of old-fashioned light timers can prevent the over-lighting of crops when ample sunlight is available without endangering crop yield when sunlight levels are low. In addition to other hardware and sensors, Candidus systems rely on Apogee Instruments PAR sensors for accurate, real-time PPFD measurements.
Dr Marc van Iersel is a world-renowned professor of Horticultural Physiology at the University of Georgia and co-founder of Candidus.

Many thanx to all of you who help us grow better...awesome knowledge, once again...

I always think the plants need a dim, overcast day. to chill out, re compose. the light control will probably depends on the crop and the intervals. some fruit crops also need shady days to develop flavour. I don't think they worry to much about flavour in the industry though

This is super crucial now in the expanding market for herbs and even animal fodder systems... especially so in my industry now that prices have tanked because of so many commercial growers now..

Very interesting I have been growing the nice herb for 30 years with many different led lights and levels spectrums and this answers a lot of of my questions with my many projects absolutely brilliant

[DeanNelsonRN]

Thank you, I appreciate you sharing so much

Great lecture. I want to build climate battery greenhouses. This could save growers a lot of money. I saw that food grown in greenhouses has a low Brix score because of the lack of infrared rays indoors. LED lighting would enable faster growing plants with high Brix readings and superior health.

Thanks for sharing the knowledge cheer's🔥🤘🤙💪✊👊🔥

I was just adjusting my par values today.

[TimMaitland]

But do we know at what point the negatives of a longer photoperiod for lettuce (eg tip burn) outway the advantages? Presumably the lights shouldn't be turned on 24 hours a day.

Amazing but I’m sure it will have an apogee price tag too…
