you probably dont want to hear this but would probably start over with a new clone or seedling, throw away the grow bulb and use a couple of cfls within a couple of inches from the plant until you can get your mh up and going.
and what is holding up your cooltube is that string? would probably suggest getting some light chain to hang your light with as its strong and easily adjustable this is just so you do not find your light fallen on top of your plants one day.
