hey all. i'm gonna be getting some money here soon. i'm looking to upgrade my light. my cabinet has about 3.5' of vertical grow space (approximate dimensons = 5'Hx3'Wx19"D). i want to do scrog in the future, but will be using my new light to flower my current plants. i know heat is a factor with HPS and MH, especially in limited space. so, would it be best to get a euro style air cooled reflector, or could i get away with a standard reflector doing scrog? here's the products i'm considering.

IF I GO AIR COOLED I'M GETTING THIS:
DIGITAL 400 watt HPS GROW LIGHT SYSTEM AIR COOLED HOOD - eBay (item 180196841356 end time Oct-12-08 14:47:44 PDT)

IF I DO STANDARD REFLECTOR...:
400 watt HPS+MH GROW LIGHT w HORIZONTAL REFLECTOR 400w - eBay (item 180180080485 end time Oct-08-08 14:26:28 PDT)

chime in and let me know. any questions, ask. thanks and grow on!:thumbsup:
