Outdoor to Indoor

I have four plants outdoors just starting to bud now. I am planning on bringing them indoors into a two car garage and using a 250w or 400w hps light. I was wondering if I needed to vent the light or the room at all. I am not worried about the smell. Thanks for any info.

If the garage isn't partitioned you should be fine, but you may need a fan if the garage is naturally hot. The light will just make it a bit hotter. You should at the very least have a fan blowing over the tops of your plants. Put your lights up before bringing the plants in, if you notice that it's too hot add a fan.
