Welcome to greystoke's Member Page
I’m from Port Elizabeth, South Africa. I’m a retired engineer, dabbling in hydroponics for a hobby. I’ve been into this the last ten years, which – in these parts – makes me an expert, but don’t take that seriously.
Even so, my special interest is experimental hydroponics. I make my own potions, and build my own systems.
I also keep tropical fish.
My zone is: South Africa(11)
