tweakin the setup. help much appreciated

Hey guys hope all is well for everybody. Just harvested off my new setup and I'm trying to step it up for the next one. I gotta 6 foot darkroom tent 400 Watt conversional light (purple Guy) 150 cfm inline and filter. Ffof soil and nutes + great white bud candy and gravity and crystal burst from Humboldt. That being said I wanna step it up. Thinkin about trying some voodoo big bud and overdrive but no experience. I was also thinkin of trying airated pots. Also temps are higher than I would like so trying to get them down. My hoods concealed so I could rig somethin up. Also I'd like to kick up to a 600 but because of monetary restrictions I can't do everything so if u got experience with tents let me know. Also ill be running super lemon and purple og18 thanks in advance

Ummm? Wow that's alot to take in. Are you asking about nutes or lights or cooling? Or the bloom enhansers? I'm lost sorry.

I think working on your environment (temps, air exchange from a fresh air source) and canopy management will give you more improvement than buying a bunch of nutes.

Nutes are only a small part of the equation. And if you go overboard they can hurt you just as much as they can help you. You can yield just fine without a bunch of additives.

I'd love to be able to run fresh air in but my tents in a bedroom and I'm wary to run any ducting through the window as it faces the road

You need fresh air. Or you can't grow. It dosnt have to come from the street but clean air is a must. Cooling and giving the air in the tent new life.

The plant in your room can deplete the co2 in minutes. So you have to keep it moving.

So u think more fans? And supplemental co2 wouldn't work effectively unless I seal the tent right?

More fans yes, added co2 yes. Together no. But I'm still lost on realy what you want to know. Slow it down give us a idea of where your at. ( what you got) and where you want to be. Don't let people lead you where that think you should be. If you Fo the next thing you will be doing is building a shed out back and living in it while your house is a bud farm.

More fans arent going to help if they're just bringing in the same stale, recycled air. As far as adding CO2, I'm not sure it's worth the expense/hassle if you're only growing in a tent.

Consider exhausing the air from your tent into your attic. Just cut a 6" hole (assuming you have 6" ducting) in the drywall, and shoot the old air into the attic/different room. This will create negative pressure in the room that your tent is in, and the windows/door can act as a passive intake, sucking in fresh air from the windows/the rest of the house.

hope that made sense...

You are definately going to need a bigger fan (400cfm at least) for a 600 and I am suprised you are getting away with 150cfm with the 400.
Then my next step would be hydro.
Forget about additives. They are mostly a con.
