Why Nordic wood?

What makes northern wood so good, superior? Spruce and pine are fully grown when they are about a hundred years old. So they have quite a lot of time to grow slowly. Cold winters protect the trees from the insects that destroy them and give the tree time to rest. The long summer days, on the other hand, enrich the tree with abundant light, because in Finland it is practically not dark at all during the summer. In the northernmost part of the country, the sun shines for up to 300 hours in June-July and 150-200 hours in August. Because the tree grows slowly, the annual rings are dense in a Finnish tree and therefore the tree grows healthy and strong.
