Humidity, temperature and lighting – VPD

In growth protocols there are multiple links and relationships between different parameters (air, water, lighting, fertilizer etc.) This next article is a bit more on the technical side and I hope will interest you. My main goal is that after reading, you understand the importance of the links between the different parameters and why it […]
Talk in micromoles, not lumens

I am writing this article because – still today, in June 2020, when talking about agronomic lighting I am asked how many lumens my lighting fixture emits or to what lux level I plan the system. The point of this article is to explain why these parameters are incorrect for agronomic lighting, to explain why, […]
Building a vertical farm requires a different kind of farmer

LED lighting technology brings with it a revolution in indoor farming and greenhouse crops. Advanced agriculture and specifically indoor farming is a different and relatively new field. A vertical farmer is a different breed of farmer, and should have a research side to their personality. Unlike the magic of traditional farming, which has an intuitive […]
LED and farming – a revolution sparks a revolution

A lot has been said about the LED revolution in the lighting world. LED technology brings to the global lighting market a change on a level that hasn’t occurred in 130 years, since Thomas Edison invented the electric light bulb. LED lighting brings many benefits to the industrial market, or to street lighting for example, […]
Spectrum, Micromole, and everything in between

LED lighting for crops brings benefits similar to those of the commercial industrial market – saving power and operating costs, controlling light colors and photometry. But plants have different lighting needs than humans. Human-centered parameters such as luminous efficacy (lm/w) or color rendering index (CRI) may not always be good indicators of the effectiveness of lighting for flowers or […]
What is PPFD?

Light for crop growing is very complex, exact and specific to each goal. This field demands patience, constant study and expertise. Let’s take a situation where two different lights are installed to light plants under the same conditions. When we put a PARMETER under the fixtures we get identical readings, however the plants react differently […]
Supplemental light for greenhouses

What should we check before purchasing lights for greenhouses? I receive a lot of requests from growers and entrepreneurs who need supplemental lighting for greenhouses. The problem is, that in many cases, these people don’t know how to define their needs. This wouldn’t be a big deal if the cost of lighting wasn’t so high. […]
Why are lighting plans so important for agriculture?

Why is professional agronomic light planning so important to agriculture, and which points should we pay attention to? When planning agronomic lighting for agriculture, the emphasis is on different parameters than light planning for spaces meant for people. Our expectations for these lighting plans are different because the users, conditions and end results are completely […]
How to compare different grow lighting technologies?

How to compare different grow lighting technologies? I estimate it will take around 6-7 minutes to read this article, so, not to waste time, let’s start from the end – it is not possible. In a milder tone, it’s almost impossible for the average grower who doesn’t have a complete experimental lab with technology specific […]
Everything you need to know about LED lights and heat

I feel there isn’t enough emphasis on the sensitive relationship between LED lighting and heat. I think that it’s due to people’s lack of knowledge, and the spreading of a myth that I am about to bust. The myth – LED lighting doesn’t give off heat. Busting the myth – this is not true. LED […]
