600w HPS height specs for seedlings

I have two Grape ape and one G13 autoflower seedlings under a 600 watt hps. Was just wondering proper height. I have them at 34 in. Should I go higher or lower? Seedlings are about 4 in tall.
 
They don't need much light at this point. I would keep it around that range and if they start to stretch, you can move the light a little closer. Hope this helps. Good luck.
