Hey what's up. I believe what we try to attain is neg psi by having the exhaust fan working harder than the intake. Or smaller or less cfm's. than the intake.
Is your intake in the light only and is your light sealed? Do you have an exhaust for your box too?

I run my exhaust fan on my veg box @ 12 volts and run my intake fan @9 volts. They are both 6" computer fans. But I have a T5 2 footer in the box not a HPS.

That's a perfect. 74.5 degrees average with 43% RH. I need some moisture so I have a glass of water in the box. It evapoates every 4 days or so.

Hope that helps.

PASSIVE INTAKE

You don't really need intake fans, take em out and see for yourself...

you'll see

nice job man!
those clones look nice.. how long do you wait to pull more clones from them? I have one about as big as the 1st pic and i'm not sure if it's cool to start cloning or not.

TY AW, as far as cloning I think it depends on what you want to do, i.e. what size/shape mom you want. If you want real little bon sai moms I would start cloning and pruning even earlier than the first pic you refer to, which is Cruella after shes had many a clone cut from her. I never get my bon sai as small as I want them, I always wait too long and keep them too big, so if small bon sai is your aim start right now. If you want more established, bushier moms than I have you might want to wait a little longer for the main shoots to develop a little. I like to keep mine small, I want them even smaller than I have. The ideal size of a clone for me (after hearing this from R) is like 1 1/2 to 2 " long. very small. AL B FUCT clones them really big. So both situations will work it just depends on what you want to do. Again I'm no expert at this

thanx dude.. i usually take them small as well.. this one mom that i have (from clone) is pretty bushy and just starting to produce 5 point leaves. I'm just not sure when it's mature enough to start taking clones from.

it could hurt.. my last grow i had an 8" intake fan as my only intake.. when i removed it and made the intake hole bigger (12" x 12") the temps dropped like 10 degrees. If you have a strong enough exhaust then a nice sized passive is better than an intake fan imho.

I'd be willing to bet intake fans could easily cut down your airflow

I have two 8" intakes (passive) and a single 8" exhaust (powered) in a pretty big flower chamber (7'x6'x9' tall) and I fully exchange air every couple minutes without a really good blower or inline fan...

And I also have a question for you...

whats a good res temp? generally speaking is fine...

I agree. Passive intakes would prob clear that up. Forcing air OUT is a better option. The passive intakes will pull what the enclosure needs, and what the active exhausts. Balance, if you will.

Yep, if your intake fans are significantly smaller than your exhaust, your airflow will be reduced to what the intake fans are moving. The only reason you would really need an intake fan is if you're trying to draw air in from a specific area, such as outdoors, rather than just letting air flow in from the room.

Res should be between 65-70F, especially if you're using a DWC system. The plants will tolerate up to 75F and down to 60F without too much trouble. Outside of that and you're going to see nute lockout.

Ebb-n-flow, and other moving-water type systems where the roots aren't sitting in the actual nute solution will tolerate even higher temps, but not lower.

thanks help_needed!

I may have an issue with cold in the flower room, but those numbers fit fine into the veg chamber (or at least this time of year it does!)
