just got a sodium 250 watt...for my plants...need advice on a few questions plz

OK ive been growing a few plants for a week now and the plants are about 3 inchs tall and a bit streched.

i just got my light and have it in my cupboard a metre above my plants,the walls are all covered with reflective roll.

now what light hours should i give it?
and how high should the light be?
havent got a fan yet,but will get a small one for vent tmr...a bit of air will get through the gaps for now am i right?
lastly im a bit stressed of how hot itll get...any chance of it burning my cupboard?

your help would be great
new grower

You won't burn the cubord, shouldn't really have any worry over that. The distance is fine I think. put it on 24/0 or 18/6, dosn't really make a diff. It might get hot in there. my closet with a 400w mh right now is 91.. not cool.

The 250 should be closer to the tops of the plants around 2feet or half a meter...most cupboards are up at shoulder height or higher....that means in the summer it will be much much warmer and that could cause a problem to the plant's health.....a 250 is for the most part pretty safe so you most likely would never have any burning probs unless it's touching something. You must have a pretty big cupboard because most are less than 3 feet high, unless I missed something??
