1kw gavita at night 8pm-8:30am, a/c off this year.
82f lights on / 75f lights off. Seems to be working so far. Your getting 90f with lights on or off?

not too good, I take a block of ice and put it in front of my circulation fan daily. Helps a bit. Need more Ice though. My T5's raise the temps 10 degrees and luckily my highest so far has been 88 degrees

As I live in Australia it can get very hot over the summer and cold over winter. I don't use a AC at all I have find that dragging the air from underneath the house will help. As temp can reach up to 120 the heat never been a problem I do run 4x10 inch fans that are 1019 cfm each.
I run 9x600 HPS with the bat wing reflectors. When temp do get very high I do have to turn my digital ballasts down

Yeah im battling cooling issues myself, 600w uncooled plus 250-300w of cfls but my ceiling fan and oscillator manage to keep temps lower than 87. Its supposed to drop back to the 70s this week though so I should be good as I am in the final week or 2

I do what fandango does and head outdoors where it's still hot but not as hot lol. I've got 10 oh zone going and 6 think different. The only issue I'm having is watering the girls daily with no rain for the last 3 weeks :(.

My biggest problem with heat, is actually HUMIDITY.

The more I run my ac, the higher my humidity gets. So I have to try and hit a balance of keeping plants cool enough without my humidity getting too damn high and lose my buds to bud rot.

are you pulling air out of the room for the lights? you should be able to get your room down in the 60's easy. I am running 4000watts and a 20k btu window unit and my room was 68 degrees ambient yesterday in a metal building with 2x4 walls. canopy temp is varies between 71-77 degrees through the day. it was 89 here yesterday.

my air flow for my lights pulls out of a separate room. or run your extractor fans for like 15 minutes every couple hr's I guarantee your room will run much cooler. let the a/c work bro!

People don't understand why i like cold summers,only grower's of cannabis that can't do legal grows know what i'm saying,keep the cold summer coming,temps 26 lights on that is with 2 x 600 hps lights in cool hood's and a 600 hps swinger,Goes down to 16/18 lights off.

If i lived some where hot i would be doing monster trees out doors legal wise that's for sure,Hoping at some point in the future to get a bar or cafe in spain,

The t5 room,28 lights on 16/18 lights off

l-e-d room lights on 24 lights of 16/18

Keep it coming i travel abroad for sun,like to do odd outdoor grow but,has long has indoor,is coming along nice all good.Got a few auto's going out doors in greenhouse that are going ok,But i'm having to do far more than normal,bring them in and out,leaving them inside the greenhouse all the time now,far to much rain for my outdoor,growing last thing i want is mold.

I'm with you 100% my heat is controllable but the damn dehumidifier is cranking like crazy. Was considering a mini-split but it's either cool or dry mode and not both. In cool mode it does dry things a bit but no where near enough to keep rh in check
