Why avoid white light in basil cultivation

Why avoid white light in basil cultivation

Grow light research confirms effect on energy consumption and crop, as experience has shown with other crops

If white light is not strictly necessary in LED installations for grow lights, it is better to avoid it. Compared to red and blue light, it does not add value to the crop, but energy consumption does go up. That’s the conclusion we have drawn after extensive testing with light recipes using the Philips GreenPower LED production module dynamic. The recent results in basil cultivation confirm previous experience in, among others, lettuce, tomato and spinach crops.

There is a lot of talk about the use of white light in LED installations for grow lights. It is more comfortable to work with white light, and you can assess the color of crops better. When people have to work in the crop on a regular basis, a little white light is therefore quite useful at times when there is no daylight available. In other situations, white light does not add any value for the plant, compared to red and blue light, and it only increases costs.

3 Tips for growing strawberries without daylight with Philips LED

3 Tips for growing strawberries without daylight;

In a few years, indoor (vertical) farms have become popular for producing healthy food year-round in urban environments and harsh climates. Leafy greens and herbs are the most commonly grown crops, but growers are looking to expand to a much wider variety of vegetables and fruits. In our Philips GrowWise research Center, we have been running trials on strawberries for several years. Recently we took these trials to the next level. Our goal? Develop a reference design for growing strawberries indoor, find the optimal light recipe and the best performing varieties.

Additional blue light does not affect taste and crop quality of basil

Additional blue light does not affect taste and crop quality when growing basil

Basil has been cultivated for centuries and is one of the most popular culinary herbs all over the world. The fresh flavor it offers cannot be matched by any other herb or spice, making this delicate plant an excellent choice to grow indoors. Unfortunately, basil leaves will turn black when they are damaged, which can easily happen when basil is exposed to low temperatures during transport or storage. Due to the delicate nature of the crop, basil is not only one of the most expensive herbs for the consumer, but also one of the most perishable. If blue LED lighting can help strengthen the crop’s metabolic profile, it would increase its value to the retailer, end-consumer, and grower as well.

Improves shelf life and vitamins in your lettuce

Did you know end-of-production lighting improves shelf life and vitamins in your lettuce?

Lighting conditions applied just before harvest determine the final yield, percentage of dry matter and quality (shelf life and nutrient content) of the crop.

Lettuce grown in a vertical farm can be just as nutrient-rich and fresh tasting as those grown in a greenhouse or outdoors

Controlling the light towards the end of production can be applied in vertical farming as well as in a greenhouse to enhance different quality aspects in the product.

It’s a common problem with processed lettuce. After a few days in the fridge, the leaves wilt or turn brown. At Signify, we performed a study to see if increasing the intensity of LED grow lights a week before harvest would improve the quality and shelf life of lettuce. And the results show that high light intensities applied at the End of Production increase key nutritional elements and quality markers, and ultimately extend the shelf life of lettuce.

Combining HPS and LED lights for higher tomato yields and longer illumination periods

Combining HPS and LED lights for higher tomato yields and longer illumination periods

Mid-September 2018, we began a new round of trials in our tomato demonstration greenhouse at the Delphy Improvement Centre. In this project, Merlice vine tomatoes from De Ruiter Seeds are cultivated under a combination of Philips high pressure sodium (HPS) and Philips GreenPower LED grow lights. We try to prove that a hybrid lighting solution can give growers a flexible way to apply high light levels to the crop right through early spring, while still taking advantage of the radiant heat provided by HPS lights at colder times of the year. The goal is to harvest over 55 kg/m² at the end of week 18.

Switching to LED means more than just switching on the light

Switching to LED means more than just switching on the light

Forget about only getting the X-factor with LED's in your tomato greenhouse. No, LEDs are part of a new system that gives access to new capabilities, such as climate fine-tuning, saving energy and slides with plant data. The limitation of a heat surplus due to radiant heat of SON-T lamps no longer exists.

3 reasons why intercanopy lighting is effective for high-wire vegetables

3 reasons why intercanopy lighting is effective for high-wire vegetables

Most commercial greenhouses are growing vegetables on vertical high-wires these days, and the demand for artificial lighting has been increasing for years. To help greenhouse growers grow their crops even more efficiently, Philips Lighting is always searching for the most effective solution. Ten years ago we introduced a new type of lighting called interlighting, followed recently by a high output version. By now this way of applying light to plants has proven itself numerous times, and we’d like to share what we’ve learned along the way.
