Multilayer nursery installs 3 kms of LED lights

May 10, 2013  By Greenhouse Canada

May 10, 2013, Friggesund, Sweden — Holmen Skog installed 2,100 units of Valoya Ltd’s LED lights to its fully automated tree nursery here.

The newest part of the nursery is a multilayer growing unit with 12 layers and it sole source of light is Valoya’s LED lights. 

Holmen Skog, a major Swedish forestry company, cultivates 32 million tree seedlings annually to reforest its forests. Most of its tree seedlings come from one of its two own nurseries.


The nursery in Friggesund has been rebuilt to become a state-of-the-art nursery with year round growing in a multi-layer growing environment and automated transplantation and quality control as well as cold storage.
Use of artificial light is critical for the cultivation of tree seedlings. To ensure high quality plants from this process, Holmen selected Valoya’s products after a rigorous testing process of different options.

Valoya’s LEDs, together with the selected substrates and growing protocols, provide high quality plants, with strong roots and full cold hardiness. The new process enables Holmen Skog to have fully controlled growth, year-round and a 100-fold increase in productivity per area.
