Faster, stronger
and more beautiful plants

Vitro Plus Burgh-Haamstede, the Netherlands  


In order to remain competitive on the international market, we constantly look for ways to make the process more efficient and improve plant quality.

I need to see 
clear evidence of results

before I believe in a technology”

Customer challenge 


Vitro Plus is a pioneering plant propagator. Based in a 200-acre nursery in California, it ships millions of tree roots annually. To meet increasing demand for trees, the company opened a 10,000-square-foot tissue culture lab. Could LED help it achieve uniform growth?


The right lighting

In Burgh-Haamstede, 350,000 plants are produced every week, and 20,000 tissue culture plug plants are hardened off. “Such a large volume enables us to see whether the results − both positive and negative − are reliable or just a fluke. I think it is fair to say that the added value of LEDs has been proven in practice. The quality of the plant growth is constant”, says Ard Stoutjesdijk.


Just making more efficient use of the space has enabled Vitro Plus to increase production by 33 per cent, and the quality of the tissue culture has improved as well. The company is making substantial savings on energy. This is partly because the LEDs consume significantly less energy than the fluorescent lighting previously used, but also because the substantially lower amount of heat generated by the LEDs means less cooling is required.


Thanks to the intensive cooperation between the two companies, which started off with small-scale tests, the results are becoming increasingly apparent. Philips and Vitro Plus have found a specific light recipe that is perfect for Vitro Plus.
