Chitting Potatoes in the Light or in the Dark? - Confusion resolved....

A quick note about Chitting your potatoes.
There seems to be a lot of contention about whether to let them sprout in the daylight or in the dark.

To find out once and for all, I did a little experiment. I stood my seed potatoes up in egg boxes, then placed half of them on the windowsill in the light, and half of them in the under-stairs cupboard where it was totally dark.

A couple of weeks later, I put them side-by-side to compare the difference.

The potatoes that were left to chit in the dark did considerably better than the potatoes left in the light.

So my conclusion is: Chit your potatoes in a cool DARK place.
