Quick question about wattage

I'm planning on growing 2-3 plants in the near future and I'm wondering how big I should go when it comes to HPS lamps? I'll be growing in my closet, but I'm gonna wall off the space so my plants have their own little section of it.

get a 430 watt son agro ,,hps,,should do fine for that setup

Keep on Growin
