As you can see, the size of the plants varies a lot. Even plants of the same variety can be very different in size.
As I normally do, I have put the chillis into intermediate-size (5") pots, not the big 10" pots that will be their final homes. I'm not sure of the science of this, but they always say that for some reason tiny plants don't like being put into huge pots. Here you can clearly see the difference between the 3" and the 5":
It was good to see that the plants all had a strong root structure.
I potted up one plant of each of 8 different varieties. I have some other, smaller, ones coming on, so I intend to eventually have 12 plants. This is about as many as I can conveniently manage, considering that I will also have potted tomatoes and potatoes to look after. I'll probably not have much trouble finding homes for my spare ones.
For the time being the chillis will live outside in one of the mini greenhouses during the day, but will be brought indoors overnight, until such time as the night-time temperatures rise to double figures.
