I passed this walking over to a mate's house last night. Gave me a giggle. I cast my mind back a decade or so, remembering enthusiastic stoners at university desperate to grow their own, looking for obscure mail order catalogues to find the equipment, trying desperately to keep it quiet and thereby ensuring that everyone knew. All they needed was a shop in Fulham. And when I say enthusiastic stoners, that's a relative term. Heh.
