Is This A Good Setup? 4x4, 1000w HPS/MH, more

Hey guys,
After a lot research I have come up with a list of what I plan to use for my grow room/tent. Im wondering if this will be a good setup. If this isn't the right place to ask, a point in the right direction would be greatly appreciated.
I plan growing in coco coir with 2-4 plants with LST, Topping, and supercropping to maximize yield. Will be running in an AC'd room with exhaust air going outside. Currently planning for passive intake with a couple oscillating fans inside.

Tent: VIVOSUN 48"x48"x80 Mylar Hydroponic Grow Tent
Lighting: VIVOSUN Hydroponic 1000 Watt HPS MH Grow Light Air Cooled Reflector Kit
Exhaust:AC Infinity CLOUDLINE T6, Quiet 6” Inline Duct Fan with Temperature Humidity Controller
Carbon Filter: Amagabeli 6 inch Carbon Filter
Oscillating fans: Genesis 6-Inch Clip Convertible Table-Top & Clip Fan
If you even have suggestions on how exactly to set up, that'd be great!

Do you think I'd need a dehumidifier/humidifier, CO2, or anything else for the tent regarding environment?

Thanks!

As long as you’re venting out of your house or out of the room with the grow tent, I see no problem at all. If it does get warm, dim it to 750 watts (which is still better coverage than a 600 watt) and you’re good to go.

Sorry, didn't see a couple of the questions the first time.

The 1- 6" exhaust is all you need.
My basement RH is about 40% so pretty decent. I keep my exhaust turned down to keep temps around 75F and to let humidity come up some. The HPS/MH seems to "burn" around 5% RH out of the tent when running. Plus its quiter/less power.

So long as you are able to supply cool air to your tent and light, HPS/MH still is your best bang for your buck nowadays.

It looks like you really did your homework and I bet you will definitly be pleased with your choices.

Do they not still advise against air cooled hoods for the de lamps? I thought they needed to run hot or you'd kill lamp life and get a screwy spectrum.

Ahh nevermind.i see they're doing a lamp chamber and cooling the chamber above now. Seems a little inefficient since you're basically just trying to cool the hood and you're not actively pulling hot lamp air out of the room. But I guess I'm some cases even 3-4 degrees f make a huge difference

Yes the Sunsystem AC/DE is the only air cooled double ended hood on the market. If this technology had come out a decade sooner.... But now with CMH, LED, etc there is so much competition for the double ended bulbs all with their own pros and cons very few hobby growers run double ended fixtures. I picked mine up used with ballast for 150$. The cheapest I have seen my hood online is 280$ which i can understand for a hobby grower would be hard to justify. add in another 200 for ballast and 100 for a bulb and you are starting to get pretty invested in something that is considered "outdated" although many people still run single ended bulbs and the double enders are putting out 20-30% more light watt for watt.

For my specific application, this setup works AMAZING. I exhaust the hot air from the light into my basement. This creates negative pressure in the grow room so it is always pulling in fresh, almost perfect humidity and temperature air from the up stairs. Humidity stays under 50% in the tent at all times and day time temps are always 75-78 and night time always 64-66.

Have u tried CMH, Chip? I like those best for veg. Just got tired of my head hitting the cheap reflectors and bulb dimming or going out. Although my 3500k spectrum 550V2 Rspec has outdone my CMH's.......my plants are 12" high after a month, 7 sets of leaves...can't even see stalk and barely stem AT ALL.

Too funny.. I banged my head alot so I added some cushion to the sharpest parts. Banging into the light is a mood changer for sure.

When I first got the hps I didn't get air cooled hoods. Once I figured out I needed them I had the extra cash.

I haven't had a Vivosun but will say for $90 on sale now, there's no chance it comes close to the quality of the Sun Systems.

I use it with a $100 Ipower ballast.

So I can buy the sun systems and pick a ballast with a bulb

Double ended bulbs put out 20-30% more light for the same wattage.
Get this hood
Get this bulb
And get whatever ballast you want, as long as its made for DE bulbs.

Yep
