Would it be any good, do you think? At least, bananas cannot be grown hydroponically as far as I know. Which isn't much because I am not into gardening or any other farming activities, especially if it involves animals because, generally, they are very messy and most of them like to bite and kick.
I do know that certain crops, when grown using hydroponic methods, produce nice plump flower heads but that is about all - just show and no substance if you get what I mean.
I dunno about that Donovan bloke. Was he from the sixties? I was there but it is all a bit hazy. Anyway, he must have been really strange if he was drying out banana skins. I should ask my wife. She was there too but was always ultra straight and very critical of certain types of behaviour. So, if he was a bit 'off' she will know about it for sure because she never lets me forget and keeps mentioning Jesus who, I understand, was some bloke with long hair who used to hang out with the Pope a long time ago and did miracles and spoke of mysterious things. Well, hinted at them really without giving you the real low down in any terms that I can understand.
They must have had some pretty good stuff back then too.
