1000w perpetual heat problem help dial in

So in the last week I really upgraded on an ambitous closet gro room. I am still dialing it in and light proofing and whatever I can, but work a lotRight now I have a closet about 7'x2'x9'ft tall. I built some tables to cut the room into two; one with 70inches of height and one with 40inches for vegging. I am running a 1000W HPS hortilux on a a 4foot rail. It has a 4in inline vortex sucking air into the attic as well as one box fan at full speed. The bottom vegging chamber is an 8bulb 4ft T5 that is vegging 8 plants and some clones. I grow in soil and use a combination of nutes like floranova, cal mag, root 66, bud candy... I currently have about 14 strains that I am trying out to pick some good mothers for the next couple of goes. some of the ones Im ecited about are Chem Dawg, Double Underdog, Blue Dream, Grape Ape, Hash Plant, Green Crack, and Mr. Nice. I have 5 going into flowering and in one month I will fill the flowering chamber with the rest.

However I am having heat issues. With the flaps and doors ajar it is peaks to 87 but since it is on a rail, I believe this temp is only for a brief period on the highest peaks. I have to use a decent amount of ducting b/c of the rail. I am just using the passive venting from the doors and flaps. I think the bottom part is running a little lower at 80 but I am going to put another little fan in there.

Is there a way to drop the heat a few degrees without switching to a 600W???
Is this way too hot to try to operate at?
Will sativas work better than indica?
Have any of yall used those heat shields for your reflector?

I would get rid of the shelf half way up. Cut a hole in the floor and suck cold air into the grow space from under the house.

Huh, that's a good idea. Wouldn't have thought of that. Seems it would work.

But it's also a bit of work for you, huh.

Alright napa wine valley bomb man, lets get your heat issues solved! Firstly, one very efficient way to drop the temperature of your grow room is by using an air-cooled reflector hood such as...

this will enable the hot air to be removed by connecting your vortex to pull heat through the light chamber and duct it outside of the room. Remember, pulling air is 4x more efficient than pushing air through a chamber. In addition, if smell is a concern because you will be ducting outside, connect your vortex to pull air through a carbon filter which will sit on the floor of your room such as...

duct that through your light, and then outside of your room . If you have any more questions don't hesitate to ask!

your ducting is too long. I just vent up with charcoal filter. Stick to indicas. I would only do a 600 inthere.
Do it SOG.
If you could. Mount the filter to the roof with bolts and chains. vent up
I just got a 12inch max can fan and a speed control. It has 1708 at max speed. Its not loud on low and the bigger ducting lets more air flow. I run it 24/7 and run a passive intake that is light proof. I use a chiller in late spring and summer time. I keep my temps at 23-26.
I think your outtake will take away your heat problem. your ducting is whats kiling you
