Orchid Growing (Indoors) What does a beginner need?

[Graham]

Hi:

I've never bought anything for growing Orchids before, so where would one begin?

Is all Fertiliser/Fertilizer the same? Or does one brand do something a comparatively cheaper brand lacks?

Bark, Coco Husk, Compost, Sphagnum Moss...do you need all of them?

As someone who has successfully grown Orchids indoors; knowing what you know now, what would be your ideal "shopping list" of things you'd need (either the "bare-essentials" or "money no object" list).
