New grow tent, exhaust and intake, need recommendations on brand

[RIS]

I think if I was going to do a tent that sized with an 8" fan I'd go with venting outdoors. You're going to be moving a crap load of air and with the door closed it's going to have no place to go. I'd rig up a dryer vent cover looking deal or gut a broken AC unit to make it look stealthy and put a good filter on the end to ensure no super critters can get upstream during a power outage. Then just tend to any light leak issues if that's a concern and all the hot air is going out of the room. I'd be concerned about the 30% humidity though. You'll need a decent sized humidifier to bring that up to an acceptable range for the room. I have a medium sized one just outside my passive intake and it can increase ambient humidity about 15-20% at best. That's for a 4*4. Trying to humidify a much larger tent will take a decent sized unit or multiple small units at each intake. You're looking for 55-65% humidity in veg, even higher with babies, so 30% is going to be tough.

I just picked up a 6L humidifier just trying to gauge what kind of increase or size I need. I’m thinking with how small this one is I’ll need a shit load lol.

I would hope two would work if you put them right by the passive intakes. Mine will let me down if I have to run the AC for a long time as that's just too dry of an air to compensate for. They catch up pretty quick once the AC shuts off and I am rarely have to run my air for that long luckily. I live in the mountains and have lots of shade to keep the house cool.

Just to follow up on the humidity discussion: With just the one 6L I was able to go from 28% to ~41%

I am going to be getting a new tent, the one I have was bought used (lesson learned). I went cheap on the ventilation setup and will be replacing that as well. I want to add an intake since the room is closed 90% of the time. I will be putting this in my office, east-facing, and upstairs. I can exhaust into my attic but intake will be from the room itself. I will have 2 or 3 1000w lights running. I have looked at AC Infinity, Vivosun, and Spider Farm.

My questions are what is the better 8x4 grow tent?

What is the required CFM of the exhaust and intake?

Currently using a 6x6 in an 11x13 room the window area is basically just dead space. Venting from tent through closet and out. Hardwood floor, the house stays between 74 and 78 degrees during summer and winter. The room does get to about 83ish and unfortunately, I have to keep the door closed. The humidity is about 30%. The room does get direct sunlight from mid-day to sunset(4-7 I think I'll track it tomorrow). computer doesn't create much heat. Airflow is pretty bad when closed. I live near a freeway so dust/dirt are going to be a factor.
If I have left anything out please let me know and I'll update accordingly.

I got an 8 inch ac infinty in my 8x16 exhausting out and a 10 inch with 10x40inch charco filter blowing air in. I cant exhaust it out of my garage so the air is being recycled as well but i leave my side door open for some kind of fresh air the intake is close to it so im hoping it pulls in some outside air.
You should be good with a 6 inch in line fan exhausting out and for an intake too but you could go bigger for both just run it lower and be careful because you will suck in your tent.

I will be adding 2 1500w HPS Lights to the 4x8. I'm looking into what kind of heat increase will be, Any idea as to if this will still work?
