Idiots guide to grow lights

I have set up a growing area under a bench in the hut, it is made with silver coated poly sheeting lining the top and back and lit with 2 kitchen cabinet lights, I have just fitted a 3ft. tube heater as well, so far I have some lettuce from seed and some of my fuchsia plants are beginning to come into leaf, I will keep you updated with how it goes

Do you have a picture of the setup Spec?
