Frankie, I think with your combination of low temps and low light levels at that latitude, to have any success you would have to invest in some growing lights. Most of the popular herbs come from the Mediterranean, which has much warmer temps and high light levels.

Since leaves are the most used part of many herbs, you may not need specialty grow-lights as you would for fruiting plants. A cheap 2-bulb fluorescent shop light with a warm and a cool bulb combination, hanging over a bench may do very well. But the bulbs need to be within 2" (50mm) of the plants for optimum growth.
