Ventilation
Your whole room will need good ventilation. The lights will need some exhaust ducting to help cool them. You will probably be ok with not having vents if you only have one light.
I have oscillating fans that blow on my plants. It keeps them breathing fresh air and makes the stems strong. You will need strong stems to hold up those huge buds you are going to grow. Basically the wind rips the plant cells just like building a muscle.
Here you can see a few fans, ducts and a/c.
