Yea pretty much, get a couple of fans if you're running 2 hps. Lights go inside the tube with ducting attached.
Fans placed within the ducting.
For best results keep your filter on a different line to the cool tubes. So each one is independent.
This your first grow?

You asked..... Here is my setup....

For reference:-

Ventilation / Intake

• Outside Air from Ground Level >>> Wall Hole Entrance with Bug Screen >>> Ducting >>> 5" Systemair High Volume Fan >>> (Enter Tent) 5" Ducting >>> Diffuser (to be fitted)

Filtration / Exhaust

• 8" Rhino Pro Carbon Filter (800m/3) >>> Reduced to 6" Duct >>> Powerplant Aerowing Air Cooled "Sealed" Reflector >>> 6" Duct >>> High Velocity Systemair 6" (720m/3) >>> (Exit Tent) Acoustic Ducting >>> Wall Exit.

Lighting

• Lumatek Digital Dimmable Pro System, 600W 400v
• 600w 400v Dual spectrum enhanced bulb & MH & HPS 400W bulbs
• 600w Mars Hydro LED (old style), for side fill if required
• Fully adjustable height of all lights to Max Height if required (Flexable ducting on Light Hood)

Environmental Control

• Evolution Fan / Temp / Rh Controller
• 4ft Tower oscillating fan
• Assorted clip fans
• Humidifier / Fogger with variable level, pumps cooling fog to plants
• De-Humidifier
• Home Built Humidifier / De-Humidifier Controller
• TFA Kilmalog Pro with 4 sensors in tent, recording temp & RH every 1 min.
• Tube Heater and backup 1K fan heater
• Other Bits & Bobs.

One thing I like is the fully adjustable De-Humidifier shelve, so you can raise or lower it as required, The De-Humidifier runs water to waste outside tent.

Lights running 20Hrs Day/On / 4 Hrs Night/Off.

• Day running:- 27.5(ish) Temp and 55%(ish) RH
• Controller switched to night settings... (you can see this at about 1:05pm real time).
• Night running:- 22.5(ish) Temp and 68%(ish) RH

Ah nice setup man, if you're running air cooled hoods already you won't see much benefit from cool tube. I used to have massive temp problems growing with hps, I would have a fan before the light blowing, then fan at end drawing the hot air.
2 x 600w hps is quite a lot of heat in a 1.5 X1.5 tent
Other options are AC unit.
