Dutch fact about tomatoes: almost all tomatoes from the Netherlands are grown in greenhouses and most are grown on rockwhool. Computer systems fertilize water that flows through the rockwhool.

The seedlings are grown in labs and then sold to the greenhouses. And while it is not really organic food, most greenhouses don't use chemicals to keep pests and diseases out. A lot of times different kind if insects are used for this. So it is as bio as it gets.

But you can argue about the taste. While they are as healthy as soil grown tomatoes I think they taste watery.
