cool tubes in sealed room

The only benefit I can come up with is lowering your A/C size/costs. Honestly, all that glass absorbs light, plus it's more shit to go wrong, and if you have the kind with the reflector inside the tube, you will have the mother of all hotspots.
That being said, I had a situation wherein I had a bit more space physically-speaking, but was a little short of electrical space. So I built a sealed room but I used tank CO2 (instead of NG gen), and used cool tubes to cut the size of my A/C.
I ran the lights on their own separate HVAC circuit. Then I just sealed the hole where the socket cords enter the tube with silicone caulk, and that's all it took to 100% seal the tubes -- I have no negative pressure in the room, nor any detectable smell being sucked into the light exhaust circuit.

Not really, it won't harm your plants as long as you place the reflector far enough away from them. Your light will be less efficient, though, because you can't hang it as close to the canopy. If you are worried about efficiency, you can simply mount the reflector on a mover, which will allow you to place the reflector closer to the canopy.

worried now.
worried now.
I have three tubes with the reflector inside. Truth is I haven't actually used them yet.
So is a 6 inline inch blowing a 1k HPS in a tube going to be enough?
I'm worried now with the "Mother of all hot spots" comment...

Yes, a 6" inline blower is fine.
Also, when I say hot-spots I'm don't mean temperature, I mean very intense light.
The hot-spots produced by your reflector won't be much "hotter" temperature-wise, but they will receive much more intense light than the rest of the light footprint. You don't really need to worry, just don't place your plants too close to the reflector. If you start to see some light bleaching, raise your lights, and your plants will be fine.

Thanks on that. I've been a safety first guy.
I think I am building a new box.. If I do it will be a roll a round.
In my old box I had great results under the HPS when they were tall and thought to add twin 250 MH in tubes to side light at flowering.
I think I'll draw the carbon intake through the 250 tubes...
Ideas Ideas...
Again thanks
Jack
