Thanks for adding your examples, Martine! I’m working (collaborating with the filmmaker Marijn Poels) on a film now ‘Return to Eden’ that features the PPUs (as part of the film).

However, personally I’m not that sure. Healthy living soil adds much more than we can see in a plant. It adds life energy, nutrients, a balance of everything life needs. As does the sun. So I’m not so sure if we humans with our LED lights and artificial growth mats can do better than Mother Nature… But I do see that it might be attractive for cities.

So I really would like the first university to study what I’m saying. How do the plants differ? On life energy? On nutrients? I do think that that’s what food is for, so let’s not sell out for uniformity, good outward looks, and easy to package…
