How can I improve the air flow in air cooled
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
Take down the light/hood and
remove the bulb.
Remove the mogul socket by
removing the two screws.
Remove the 4" duct
Step 2. Cut out vent, using a Dremel,
Zip, or similar tool. Repeat for inlet vent.
Be smart, use safety glasses and don't do this
your hood (mogul, adapters, etc). Optional
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.
