T5 HO's hot hot?

I'm in the very, very slow process of building an indoor veg closet. My wife allotted a 2x2 foots patch of closet. LOL. At any rate, I was thinking since it's 2x2 then 24" T5's HO's would be a good choice. I wont have the luxury of tons of ventilation in this space since it's right by my back door. How hot do T5's get? I'm still waiting on the ballast to arrive but it's capable of running 6x24" bulbs. I forget the exact wattage but it's around 150 or so I think. Once I get everything installed then I will add more ballasts and T5's as the heat will allow. How hot will it get?

my HO T-5's are 2 ft- 4 bulbs. They work great for vegging 6-8 plants. No heat...:thumbsup:...(unless I close the closet door all the way...:smokin:)

if a partially open door is your T5 cooling then perhaps a quite running pc fan would be enough to properly vent the space. I was thinking that since I have the means I would go ahead and install a small 120mm vent. I'm hoping it will be enough. Find out soon. :)
