I find the variety 'Gardeners Delight' one of the best for heavy cropping and taste.Like the other guys have said watering at regular intervals is really important, i use a speed feeder which is just a plastic pipe with a plant pot on the end.
plant 3 to a grow bag, buying an autovent is also...
This one looks quite good value, i payed £330 from a local shop with only two batteries

Hi mate do you know what variety of potatoe you have got.I'm using "Rocket" this year which are very good for planting early on when the weather is colder.
