After reading various articles I decided to go with Monty's advise and plant 2 seeds in ordinary 3 " pots. Root trainers etc. were getting expensive and I haven't collected enough loo rolls. I am germinating them on a dining room table which does not get bright light and is reasonably warm. The plan is to put them in the shed once they have all germinated.

Germination results so far (8 seeds planted of each variety):
Black Knight: a big zero
Matucana: full house - 8
Lord Nelson: 5
Painted Lady: 7
