who went to that workshop (the one that was meant to be in a squat, but ended up somewhere else) a few weeks ago?
anyone know if they'll be doing it again?

my friend kate says: "it's not rocket science", and (echoing the sentiments above) that all you really need is patience, and maybe a tensiometer.
i was toying with the idea of building some this summer, but ran out of patience. ;)
