vert lights dont have reflectors, thats the point

i suggest putting the vert light in a vert cooltube with one open end and one end attached to a big fan

just remove that crappy tin foil reflector thingy that comes with the cooltube.

Some are.. It could be in a high-bay, or one of those umbrella looking reflectors.. Clarification before suggesting plans would be good..

I dont want to use cool tubes. If I have a fan per light blowing right on it do you think it would keep temps down?

and how would you keep temps up at night?

ok so you dont want to use cool tubes, i dont know why
how about other glass tubes attached to a vent and fan?
failing that, put the fans BELOW the lights blowing up to encourage the heat to go up instead of across
and still have good air movement / extraction

It all depends on what size room they are in too. If your doing verticle, I take it that you are using an entire room?

I've seen a vertical grow where the guy just put a fan underneath the bulbs. The fan was just laid down on top of a bucket and blew air at the bulb. Then he had exhaust fans that took the heat out.

Really, you can't. The heat given off by HIDs is radiant heat which means those galss tubes are useless. Just keep the air moving and keep them a safe distance from your plants.

In this pic I have a fan on the toilet blowing up at the bulb and a fan in the doorway on the floor you can't see blowing cool air into the middle of the room.

I could have stuck a squirrel cage fan in to exhaust from the ceiling and not have to have an open door with a fan in it but my back hurts too much lately and this was just for one grow anyway. It's a 1kw hps in the middle you also almost can't see at all, not that ceiling light.
