Swift potatoes and Gro-Kit

I am a novice / newbie, this year will be my first attempt at growing my own veg! I have got a small plot at the bottom of the garden and also bought some seed potatoes and Gro-Kit so I can grow them on the patio.

I have started chitting my first earlies (they are called Swift) they were in my shed in an egg carton for the past week but no sprouts have appeared, so today I bought them in and have put them on the window sill in my kitchen to see if this change in environment will encourage sprouting. However I am now worried by me bringing them into a warmer climate I may be doing more home than good.

Can someone please advise whether what I am doing is ok, or should I return them to the shed.

The shed is obviously much cooler but does have a reasonable amount of light.

Many thanks

Thanks for the welcome, and for the quick reply. Shall I put them out in the shed again?

I read these seed potatoes can be planted by the end of February, if they haven't chitted by then will it hurt to plant them later?

Cheers DIGGER, I'll take them back out tomorrow morning and leave them to do their thing.

When planting seed potatoes I have read some people leave all the sprouts on, others leave between 1-3 sprouts. Have you any advice on this, and how can you differentiate between a good sprout and a bad one?

Thanks for the advice Salmo, I'll leave them on the window silll then and keep an eye on them. Once they start chitting I'll put back in the shed.

The shed was cold and frost free so a good place for storage, but too cold to chit.
Now they are in the warm they should start to sprout after about a week.
Once they have started to sprout, you can store them (carefully) in the cold again until the weather/time/conditions are right.
Mine are still in their original net bags (unchitted), as they are easier to store like that and I'm strapped for frost free space atm.
