#1 Do you think in a grow box that size i could do without the reflector hood,would the lumens remain the same? or should I keep the hood?

I figure I could probaly lessen the heat by removing the hood! and just let the bulb hang!................but if I am going to lose a big amount of lumens maybe I should keep the hood?,,,,,,,,,I plan on getting either a ac unit in the next week or so,or make my own fan with glass for the bulb.....do you think if I removed the hood my heat would reduce alot???? here are a few pics.
first, that is a great growbox to remove the reflector...you just have to put reflective material on your ceiling to reflect the light downward
It will be brighter than it was when you had the feflectors...if your lights are low, I mean early in grow when plants are small, you can build/fabricate a lightweight frame that you could wrap in panda plastic(my favorite,reflective material) and hang it 6"-12" above your lamp, depending on how cool your fans get temps in there around the bulb. I have a small $5 wallyfan about 2 feet away pointed right at my bulbs and I am flowering my main kolas 9-12in away from the bulbs...
2nd my temps went down 10-12 degrees when I removed the hoods. hope this helps you out, nice little area you have there, luckier than most.
