The reason that your seedlings and cuttings are so poor is indeed the atmosphere. Growers can give their plants ideal conditions, whilst yours have had poor light and been too warm on top of the radiator - that has encouraged them to grow lanky.
Before puting them out in the garden, you should have been putting them outside on warm days and bringing them in at night - that would have helped them to thicken up. You still need to do this before planting them out now, for at least a fortnight.
Once your fuchsias are outside, they will improve considerably, and you should find that they (and most of the seedlings) will give you a good show.
