i just got a 250w sun system 2 hps and i looked in my room today, my white widow is burned to shreds.

so heres my question about the light. its supposed to be "air cooled" but my room stays about 85.

if i buy the glass will it make it any cooler? and also can i just hook a duct up to it to make it cooler and will the air blow out through the duct or will i need a duct fan to pull out the air?

please help quick my baby is dying :(

if ur light is in an enclosed glass tube then it is air cooled. if u have a reflector that says air cooled, then u will have to attach the duct & the fan for it to cool the bulb. Now I have the latter, & I simply keep a fan (attached to the wall) running towards & at the reflector the whole time the lights are on to help control heat & keep the bulb cool. hope this helps ya!

ok, and there is no place for an intake point, just one spot for ducting at the top

If there's only one port at the top, you may have to just run it without the glass. Just connect a good exhaust fan to the other end of your ducting and pull that hot air out of your cab through the light fixture.

Something like this for your closet door or another way to draw air into the grow space;

I grow in a closet.
What I did was cut a 4" hole in the door and installed a passive intake vent w/ a light cover (Basically a hole in a door. Use caulking and wood glue and do it right).
Then because of space, I had to adjust a little. I connected a small cut of ducting to the carbon filter and the other end of the same peice of ducting to one of the holes in the air cooled hood.
Then on the other en of the light, ducting to blower.
Then from the other end of the blower, to a vent in the ceiling.
So..
Stale/Smelly Air------>Carbon filter cleans smell----->Through the light hood cooling the bulb----->Through the blower/inline fan------>out of the house.
I think I have some pictures....

And yes, the light must OBVIOUSLY be sealed.

i wish i could do it like this, but like i said up there, there is only one spot for ducting on the hood, and its on the top

that is 85f? not 85C?, 85 farenheit should not harm your plants, unless they are too close to the bulb 250hps isnt a big lamp, so maybe its not the temperature thats the problem

If there's only one port, and you connect a fan to this port to pull hot air out of the cab, the air has to come in from somewhere. With no glass in place, the hot air will be pulled in from your grow space, through the fixture, and up and out through the ducting and exhaust fan. If you have glass in place, where will the air be pulled in from? If the glass is sealed tightly in the fixture, and you have no other openings, you'd just be creating a vacuum in your light fixture.

Most air-cooled hoods have an input and an output port (usually on the sides). The glass seals the fixture, so air is pulled in through the intake port and is exhausted (along with the heat generated by the lamp) out through the other port. There has to be some kind of opening for air to be pulled in, if you're going to exhaust warm air from your lamp. With no glass in place, you have an opening.

Maybe your fixture has some vents on the side? That might help a little, but still would probly restrict air flow.

Thats not heat....
I see Mg def for sure but everything I'm only partially sure about.
I'm pretty sure there's some over-fertilization there.
Idk, looks like multiple nutrient problems due to pH problems/salt build-up
