HOT Room (Temperatures)

I am sitting a little higher than I should (a couple degrees maybe 4-6C). At around 30C./86F.
Already have an ac running. 8" inline fan to exhaust heat. Passive intake.

Would adding a 4"inline INTAKE help cool the room to a suitable temperature? Or another AC (not optimal)?

how do you have your a/c air getting into your room? I have mine being sucked in by my intake fan. I taped 1/2 the 6" ducting off the ac to 1/2 of the 8" intake fan.

I suggest cranking up the fan speed on your intake fan (if so equipped), and lowering your exhaust fan speed. the exhaust may be sucking out too much cool air and your a/c intake fan setup might not be able to cool the room quick enough. I ran into the same issue. was running 81* (12" below the bulb, 3x600hps air cooled with 2x 8" 720 fans). I cranked up the intake fan (8" 420 cfm), put my 14k btu ac fan speed on high, and dialed down my exhaust fan (8" 720 cfm with monster scrubber) to about 75%. now im running 75* all across the hoods 12" below the bulb.

Right now I have a passive intake. Before spending money on an inline fan for intake, I was hoping to get some info on whether or not it would be worth it (would it solve my problem)?
I have a portable ac stationed in my tent, exhausting the host air from the ac out and away with a duct.

That's interesting, I never thought about that- ac not being able to cool room fast enough, and exhausting too much out.

I never understood people who used AC and exhaust fans together.

What is the first thing you check when u turn on the ac at your house? That all the doors and windows are shut.

Why are people paying for cool air, just to suck it right out of the room?

Btw, that portable is an energy whore. Eneffecient as all hell. And leak smell like crazy.

86 i found to be perfect temps with right humidity and little co2 boost Stomata stays open more :) thus better overall growth pattern just remember plants will uptake more volume of water so you need to back off nutrients or plants will show burn signs Leaves within a canopy may experience rapid and extreme fluctuations in ambient conditions. A shaded leaf, for example, may become exposed to an order of magnitude increase in solar radiation within a few seconds, due to sunflecks or canopy motions. Considering typical time scales for stomatal adjustments, (2 to 60 minutes), the gap between these two time scales raised the question whether leaves rely on their hydraulic and thermal capacitances for passive protection from hydraulic failure or over-heating until stomata have adjusted...

i don't care, ill take my 73-75* temps when running 3x600 any day. who care about a 500.00 a month power bill when you grow medicine for 6 people :)

Holy shit that is high for 1800 watts. How much do u pay for kWh? I run a house with 3600watts, 24k mini split and 170 pint dehumidifier in flower, 800 in veg(those are only on a week every two months) and my power bill stays at 3-400 bucks.

um, I run 1x600mh in vg, PLUS 5x 4'4bulb t8 6500's, plus a 14k btu ac, alarm system, my buildings power needs (tv laptop, internet/cable), 3 x18" fans, 3x 8" 720cfm fans, 5x 6" 440 cfm fans, 2x cloners, then my drying room (dehumidifier), and office power needs that I relax in that also have a window shaker unit in. and 1200/mo lease on the building.

I also run perpetual so my setup runs day for day.

That's a whole lot of equipment for the size of operation, no offense. Your veg room alone is over 200 bucks a month in power. My buddy runs a 1800 watt room, perputaul also, veg for 3 weeks under a 6. 3 week rotations in room. Power bill has never been more that 300. He lives their too.

But like u said, that 500 a month isn't shit.
