150 watt HPS enough to veg 4 plants?

[deadkndys]

I was wondering if a 150 watt HPS would be enough to veg 4 plants for 5-6 weeks under a 18/6 light schedule?

By the way I am working with about one and a half Square feet.

Is that the only light you have? If you have a switchable ballast I would advise a 5500k MH.
I also don't think you will have enough penetration from 150w if you veg for that long.JMHO

That lamp should suffice for the space you have... although it seems like you will overgrow that space if you veg for 6 weeks. my 2 cents. Good luck
