Well, first, they weren't that expensive (2 for $72 inc ship), but my dream light is a 400w CMH in a SS Supersun2 hood. Growing in a triangular space forces all the heat up to the top of the room really fast, so the exhaust/temp situation has got to figure into the purchase of any HID light system. Plus it has to be quiet - I have clients & customers in my workshop/studio that would notice a hoover vaccum cleaner running full time in my closet. I'm waiting to hear some more reports on the S&P 4" Mixvent fans cause I know a vortex/canfan/elicent would be too loud for my situation. If it turns out that I can use the S&P 4", then CMH here we come!
Still... I have some great memories of my first shoplight closet grows from years ago, so I'm kinda sentimental about anything fluoro - i know the T5's can kick some real butt & are probably the perfect no-hassle lights for any apartment/stealth grower.
Yes, I'm putting together a "poor man's" grow journal as we speak, but I'm gonna take my 8 hillbilly bagseed girls thru flowering before I post (just in case I kill everything).
