how do you mount your ballast and co2 controller on the wall?

I have a grow tent and ive seen pics of the controller hanging on the tent itself. that makes me a little nervous for some reason and i was going to try and mount it on my concrete basement wall next to my outlets.

does anyone have any pics or could anyone lend a hand here, cuz im havin some prollems. thx!

i guess this is what my question.

should I drill my controller and ballast directly into the concrete, or mount it into a wooden board and then attach it to the wall...

dude as far as attaching to concrete if you drill you need to use put those little plastic anchors in the hole to secure it ,and they work great.
Im not sure if you know.
and they also have self tapping concrete screws that should work by themselves.
but its hard to tell w/out pics.
