My Grow Room Set Up

ive converted an attic bedroom into a growroom. i divided it by half with a sheet of heavy plastic to better control the temp and climate. ive blacked out the window and made a 10" stealth vent in it so i get completly fresh air. the vent is not visible from the outside. i got a 1000 watt MH and a 400 watt MH along with the same HPS ballasts. the room is 7'x4'x7'. I just want to know your opinions and some advice if you see something that should/could be improved. this is my first grow and any advice i would appreciate

Looks good. How many plants you got and what strain(s)?

right now i got 7 plants. 2 super shiva's 2 white widow 2 nevilles purple haze and 1 northern light

How big is the grow area? How are you going to control the temp?

the area is 7'x4'x7'. I installed a 10" duct with a 9" fan attached to the end. the other end is directly outside and winters just starting so i plugged it into a thermo outlet that tells it to turn on @82 degrees and turn off @72 degrees. during the summer im probably gonna stick an a/c in the window thats inside the grow area. any advice for me mogie based on what you see?

Seems like you have all the angles covered... now comes the fun part.
