I am stuck on what reflector to purchase though. The two I am looking at are similar but one has fan holes and a glass cover but is $50-60 more. I know i should probably purchase it so in the future i can use it for better cooling but would i be able to get away with having a fan blowing on the hps for sufficient cooling until i can find a good inline fan?

I am not growing in a little closet or box but rather my attic space.
For anyone who considers growing in attics I always give them this link first http://cannazine.co.uk/indoor-garden...eme-sport.html


No my ballast is well outside my grow room I use a maxibright compact switchable ballast.

Also If you are starting seedlings get a couple of CFLs to put them under for the first couple of weeks/whilst you wait for your inline fan.

As stated earlier having an inline fan just above my HPS seems to keep the temps low and good airflow through my grow room, remember reflectors can always be upgraded I know alot of people who grow with the standard euro reflector and have no problems.A better reflector will give you a few more lumens I can't see it making a massive difference to your grow.
