Thanks DJ and P.
a little update kind of bad news but not really. Yesterday i hooked up the second 400w hps everything was looking good for about 6-7 hours but then i noticed that the plant on the right top leaves was curling down a little bit and i did my research and found out it was from the heat so i unplugged the second ballast. The plant on the left showed no signs of this probably because the fan is on the left side of my tent. So i decided to add another fan to go on the right side of the tent. this whole process of research and getting the other fan probably took no more than 30 mins. I set the fan up and plug the ballast back in and NO LIGHT. I figured the ballast might need some more time to cool off so i unplugged it and decided to let it cool over night, well today when it was time for the lights i plugged the ballast up and still no light. so i unplugged it and took the hps bulb out, switched the ballast to MH and put in a mh bulb and the light work. So i blew my 400w hps bulb after only getting 6-7 hours worth, but at least i didn't fuck up the ballast. Right now i got one 400w hps and one 400w MH going. I'm going to get a replacement hps bulb later this week. So if its any new growers that subscribe to this grow learn from my mistake.
If a ballast been running more than an hr and you have to unplug it for any reason make sure you allow time for the ballast and the bulb to completely cool off before plugging it back up.
