Most plants need about 5 + hrs. Look it up on the internet, google it.

We used seed potatoes to grow Kilgore in our school garden. As the tops have now died off we harvested them today, only to yield Ferny tiny potatoes. Less than 300g from a whole 3.6m x 1.2m garden bed. The potatoes were watered a minimum of 4-5days per week, were regularly fertilised and grown beside sweetcorn. How did this go so wrong. We yielded less than the bag of seed potatoes that we planted. The soil was beautiful and rich. We mounded around the growth for the first 6weeks. So disappointing. Any help greatly appreciated.

I would say you over fertilised them way too much, and probably too much water. That would produce a lot of leaves and little potatoes. In future prepare the ground adding manures compost etc., don't over do it though. They WILL NOT require any more fertilising. When young a lightish watering each day or two. When bigger a good watering 2-3 times a week, depending on temperatures. Put your figer in the soil to see if wet or dry and water accordingly.

Are the green potatoes safe to eat? I always get a few in my crop

IT IS NOT SAFE TO EAT THEM. It is caused by the potato being exposed to the sun. In future keep the potatoes covered with soil to stop this happening.

Can I plant seeded potatoes the week after Christmas for a winter crop? And also if yes what seed potato would be the best? We live in north Canterbury

First decide whether you are temperate or cool/mountain - look in the climate zone section. Then read up about the planting times. Then you decide what potatoes you are going to plant. That will depend on what is available in your area.

sammy when your potatoes have reached a few inches high get a garden how and pull the soil up either of the plants sides that will give the plant the soil to grow in.I would have worked horse or cow manure into the soil before planting the normal guide to plant potatoes is the first week of Aug' that will give you spuds just before Xmas and plant again 1st week of march.It's best not to plant 2 crops in the same soil
