Got the fan....too expensive? Oh yea.
I use 12volt fans from dumpster dived computer cases (power supplys have fans) , a 12v converter is need (thrift store {second hand store} if you don't live in a materialistic area of America where it's cool to throw stuff away) use thre and you can get quite the wind going. use some up top to blow (suck) the heat away.
THROW AWAY THE INCANDESANT BULB. THE MOSTEROSITY IN BLUE...MARKETING BOY, THATS ALL IT IS MARKETING... USE IT AS MOOD LIGHTING (WELL AWAY FROM YOUR PLANTS) THINK OF IT AS YOUR FIRST MISTAKE....I've had many and still counting.
Never discount the power of airflow, too many often do.

Well, if you look at my most recent pics, you'll see that I don't have any incandescent bulbs in my set up anymore. Also, I already set up an airflow system with a computer fan with a carbon scrubber and a passive intake as well as a little fan or circulation.

Thanks though!
