What kind of ac do you have?Hey guys! I’m trying a new bigger set up and while maintaining the climate in a small room was easy enough, now that my grow space is twice as big I’m not sure what to do about the heat.
The grow room is around 225 sq ft of which I’m using around 170-180 sq ft for the plants. I have 12 480W LEDs and boy do they heat the room up. I got a 600 CFM exhaust fan (the intake is passive from the outside) and when it’s on, it gets up to 90°F. If switch the fan off the temperature goes all the way to 97°F. Meanwhile both of my 12000 BTU A/C’s are busting their ass off. It’s also worth mentioning that my walls are insulated with polystyrene foam sheets. So my question is, is it possible to keep the temperature down or should I just seal the room and go for CO2 enrichment? Thanks!
My ceiling is about 8.8 feetHow high is your ceiling? No expert here, but your exhaust fan may be to small.
I have a 12000 BTU split-system and a 12000 BTU portable a/c unit exhausting hot air directly outside. Feels like this should be enough. Perhaps my exhaust fan is not cutting it indeedWhat kind of ac do you have?
Thanks man, I hope I'll figure it outI’d upgrade to a 10 inch hyper fan that way you OWN IT! It will quickly exhaust the room when your ac units aren’t cutting it. I’m surprised that 24000 total btu in ac power and your still fighting it. I have 375 sq feet and a 24000 btu mini split does the trick. It can get a little warm during the two hottest month of the year but otherwise it’s plenty. That’s running 7000 watts of hid, a co2 gen from which I removed and plugged two burner ports to reduce heat (still is plenty for the entire room) plus another 400 watts in led. I am surprised your having issues. I use a 10 inch hyper fan off a ginormous carbon filter to exhaust humidity to outdoors and it still kills it! Something seems like it’s not adding up yo? Anyways I wish you the very best and I’m sure you will figure it out.
What is the outside temp and are the acs window acs? Im a retired hvac/r engineerYes. The hyper fans use less electricity than conventional. Cost a bit more but worth EVERY PENNY! They come w a speed controller too I hear ac infinity makes a kicking product as well I bought mine years ago before ac infinity was around I’ve got an 8” intake HF also for when I’m not running co2 the 10” barley turns on cause I have it exhausting humidity so it doesn’t deplete my co2. Ya don’t even need co2 unless your plants have ALL THE LIGHT THEY CAN ABSORB, then the co2 enrichment allows them to photosynthesis and create more energy from the amped up lighting bla bla bla. Sry didn’t mean to ramble. The 10” It earns its keep at lights out when the humidity skyrockets it takes it down within 3 minutes View attachment 1130208
This is the guy to talk to.My room is 13X16 or 208 sq ft. With 12' ceiling.
A active intake ac infinity 10" about 1200 cfm with two 8" exhaust 1600 cfm total.
Split ac is really only needed when intake air is near or above room temp

Pictures help. Exhaust ideally would equal intake I'm running on negative pressure at full on.Are two exhaust fans opposed to one big one much more efficient? Just curious to understand more
I see. Very nice. Way to own itPictures help. Exhaust ideally would equal intake I'm running on negative pressure at full on.
If I had non vented lights it would be a 10 inch active intake and 10 inch exhaust.
hvac engineer here, your heatload far exceeds the amount of cooling you have. i have a 12 light room and dehues/fans etc and i have 48,000 btus cooling. if i got all the info i could do a load calc for youHey guys!

Your exhaust fans placed within the room and your fresh air intake where about is that located? what color is your roof? What kind of siding do you have? And whereabouts in what country are you locatedHey guys!

How tall are your ceilings? LED shouldn't produce that much heat? How many watts are you pushing through those LEDs?Your exhaust fans placed within the room and your fresh air intake where about is that located? what color is your roof? What kind of siding do you have? And whereabouts in what country are you located
