Recently ive learned that most wasabi that you get in my country is actually just horseradish. There are a couple of very expensive Japanese restaurants in my area because of the japanese consulate. Do you think they would be interested in buying real wasabi? And how difficult is it to grow it in a central european climate? Ive heard you need a flowing body of water and they could take 1-2 years minimum till you can have your first successful harvest, but it doesnt seem too difficult.
