i usually work with one for first couple of weeks too but i find that my 2 x 600,s give me an ideal room temp so i just use the 2

id say all depends how close you can get the lights to the plants with keeping the heat at bay, as you dont want to stretch the plant ,

Once the plants have enough leaves on them to benefit from the extra light.

I usually wait until they have two pairs of real leaves then swap to the MH for vegging. no point in using HPS on seed leaves as you run a much bigger risk of burning them.
