There's hippies and there's hippies, Sam
Whether or not you talk to the spirits of the plants you grow does not matter nearly so much as the fact you're growing plants.
If you're sitting around talking to the spirits of plants you only dream of growing and have never actually planted anything, well, that might be another story.
We all fall somewhere on a spectrum, and very, very few of us have either zero hippy or zero establishment.
Permaculture is revolutionary - hippies identify pretty well with that - and so do some pretty radically different demographics. All good, as long as the ideas are growing and getting acted upon.
