Thanks for the apology kieahtoka. In responce to tokecrazy, originally the tops of the plants were about 20 plus inches away from the glass on the hood. I had ac, but not enough airflow under the light. I was getting a LOT of heat from having the glass pane attached. THE REASON I bought the hood with venting holes was so that I can vent it when I move my op into another room and increase the scale a bit. I just wanted to be able to have the option in the future. With another fan in the room, my light raised a few inches and the glass off, things have cooled down substantially and my girls are rebounding nicely. Thanks everybody for the help and criticism.

How can I improve the air flow in air cooled light hoods?

Step 1. Take down the light/hood and remove the bulb.
Remove the mogul socket by removing the two screws.
Remove the 4" duct adapter.
Step 2. Cut out vent, using a Dremel, Zip, or similar tool. Repeat for inlet vent.
Safety Note: Be smart, use safety glasses and don't do this stoned.
Step 3. Reassemble your hood (mogul, adapters, etc).
Optional insulation:
I use some of that bubble attic insulation (or hot water tank insulation - similar to foylon) you find at most home improvement stores to make an "insulating blanket" for my hoods - every little bit helps.

Like many of you, I use Hydrofarm hoods for my lights. I also air cool them using the 4" adapters sold by most hydro shops. Now, one thing you'll notice when attaching those adapters is the "grating" over the location where the adapter goes. It doesn't take a rocket scientist to realize that those slats are going to impede air flow. So let's remove them and give a real boost to our air flow.
