do you have your lighting schedule set to optimum timing vs natural heat? (setting it to it's dark period during the hottest ambient temperature times?)Does anyone know of a small a/c unit that can fit in a 5x5? I don't need a large unit. Just one that can bring the temp down a little bit. And I have a/c in my house but the tent is reaching close to 90f in a house that is around 70f.

20F rise is pretty high.Does anyone know of a small a/c unit that can fit in a 5x5? I don't need a large unit. Just one that can bring the temp down a little bit. And I have a/c in my house but the tent is reaching close to 90f in a house that is around 70f.
That is completely normal IF you dont have proper airflow. Wether youre using LEDs or not youre generating heat constantly rising the temperature inside the tent, and that heat wont go away unless there is proper airflow. If thats your case then invest in that first as it will also refresh the air inside, its good for your plants in many ways. If you already have ventilation and still reach high temperatures then yes, you might wanna buy a mini AC but I cant help you with that, maybes someone else can recommend you one.
It's a 5x5 set up in a 15x20 bedroom with good airflow. The room stays pretty cool in the summers, that is why I set up in that room. Last year I had two smaller lights in the tent and it did not get nearly that hot this year. I have a brand new phlison FD6500 and that bad boy is putting off some heat20F rise is pretty high.
What do you have lighting (watts) and is it in a closet or small enclosed area?
I have a 5x5 in a large bedroom that reaches maybe 72 on a hot day. I have a 6 inch fan and filter. I'm running a clip fan and a 10inch table top fan. The inside has good airflow and tried different fan positions. I checked this evening around 9:30pm and it was still 88 degrees with the ambient temp of 65.I'd rather hear more about the set-up before recommending a portable AC unit. If the tent isn't in a confined space, the ambient air temperature in the low 70's should be sufficient to cool the interior of the tent. The OP would need to introduce fan driven intake air. I use a 6" carbon scrubber to deliver clean cool filtered air into my 5 x 5. My 8 x 4 has an 8" carbon scrubber filtering intake air. Both tents also have an 8" carbon scrubber exhaust system. If the ambient air is already cool enough, then air flow through the tent should be enough to cool a tent illuminated by LED lights. HID are a different story and a person would be better off enclosing an HID in a cool tube with active air exchange.
I have a portable AC unit in storage. I'm not a fan of them. They are extremely expensive to run and not all that efficient.
Yes I have a 12 inch carbon filter installed at the top of the tent to also suck the heat out. I think the light I have is getting too hot. I have followed the manufacturer recommendation on light intensity and height which the plants are liking pretty good. The phlizon light works really well but I think they might need to figure out how to produce less heat. I'm thinking I'm going to get another intake fan and feed it through the bottom to pump cool air. I feel like that has been the best advice I have received so far.You could put another 6 inch forced intake fan and or get a bigger carbon filter for better air flow. I assume your exhaust fan intake is near the top of the tent with air intake at the bottom . 65 degree lung room of that size really should be able to handle 1 tent.

Odd I’m running the same light in a 4x4 I’m only at about 30% but I had it crankin during the last run she does put out some heat for sure, but I was able to handle it with just a 4” spiderfarmer exhaust and carbon filter, my sensor will read 90 if I don’t post a mini hood on it to block the light from hitting the sensor directly, can you give us a temp sensor location?It's a 5x5 set up in a 15x20 bedroom with good airflow.

Is tent vent dumping in room or going outside, if dumped in room, you are sucking that same hot humid air back into tent..Yes I have a 12 inch carbon filter installed at the top of the tent to also suck the heat out.

65° is main house or in grow room ?
My 4x4 's have 6" ac infinity t6 temp/humidity activatedI personally think we have a airflow problemwell a volume issue. That 8" is probably not enough for both tents. You can force air in but is needs to be pulled out. Have you tried using the 6" as a exhaust that connects to your 8" in mind a 6" is the bare minimum for a 5x5 and it better be a top of the line pwm inline fan. My 6" is advertising 400cfm it's perfect for my 3x3 or a 4x4. You would think a 5x5 alone would need 500cfm.
I agree with the HVAC issue venting outside I don’t run AC I just have my tents in the basement,It's not that simple. Venting outside opens up a whole bunch of new variables that the home was not designed to handle.
In a modern home, heating and cooling is a tuned system and venting outside changes it efficiency dramatically. It also sounds like the room that the tent is in is large enough to handle the warmer exhausted air from the tent and still maintain upper 60's/low 70's ambient room temperatures. @Southernuncle21, is this correct? I vent into the same room without issues. I'm using 2 larger tents and 3 large LED bar light fixtures in the same room without issue. My ambient air temp is in the lower 70's outside of the tent and my tents seem to settle out at about 80f.
Hopefully an HVAC specialist will catch this thread and fill us in on the details.
