Finished Grow Room Suggestions(Pics)

I just finished my new grow room. I posted this in a diff thread but didnt get all the answers I was looking for so Im lookin for any other advice. The room is 12.5'x6.5', I mylared all the walls, & right now Im running two 1000W HPS. I have another batch goin straight to the flowering room within the next week & will be adding another 1000 watter. Except for adding some more electrical boxes I think Im basically done. Right now the temp is around 78-80 degrees & R.H. around 49% w/ the 2 lights. 1 question I have is do I keep the bulbs in the hoods or just let them hang freely? I heard keep them in the reflector but Ive seen people just letting them hang w/ no Mylar. Thanx.

Fans, Fans, Fans. You need air flow brother. Get you some fans going high and low. Why are the ladys off to the side. You need to get them under the lights, in the middle where the lights are strongest. I can't tell what kind of hoods your using but I would say you need to get high velosity fan hooked up to get the hot air out of the room.

Thanx for the reply bro. I do have 2 adjustable height fans but I don't need to use them right now cuz the temps are basically where I want them. I know I will need them when I put the 3rd 1000W HPS in. In 1 of the pics you can see where there's some gaps about 1' wide by 8" tall at the top of the wall these about 10 of them total to help w/ ventilation. The temp is staying closer to 77 which is close to normal. Also, I am putting the plants under the light. I moved them to the sides for the pic, I had just put those grates down so they wouldn't be sitting directly on the floor. I'm gonna be takin clones as much as possible so hopefully ill eventually have the grates & both sets of stairs covered. I want to be able to put at least 20 new plants in every couple weeks.
