I have also ordered rhizomes from Willingham's, WGV and Fuggles. I have never grown anything ever before (except grass and some weeds) so will be keeping a watch on this thread.
I have them in pots at the moment waiting for the weekend, when I will be digging in some fertilizer.
A good shop is, Specialist Home Brew Supplies lower ground floor 697 Llangyfelach road. Its round the back of the chemist, if the door is locked ring the door bell, I buy my stuff from there or the internet.

Guys, the heat and cool are the wrong way round. Pins 5, 6 are heat. Pins 7, 8 are cool. I have one and that is the way mine is wired, i used the same diagram you posted, but an updated one with heat, cool the correct way round.
