Got central AC installed last week, now have basement AC and it makes things a million times cooler and dryer.
Not a ton of easy fixes for summer heat that aren’t air conditioning.

After testing my spider farmer lights(led for two grows I have decided to go back to pure cmh or cmh and in flower cmh and DE HPS 750 watt. Heat will go up with pure cmh I know, but not as much as the LED peeps make out. with my infra red the difference between the LED’S and the Cmh at most was 25 degrees F, and avg about 18F

I’m as cheap as they come. My veg is 4 double led shop lights bought at ocean state joblot for $15 each. Cut plastic tube in 1/2 exposing led strips. Thats it for a 4 x 8 veg, no heat girls love it.
Flower is tougher. I run an AC in a 4 x 4 clean room. To draw air to 4 x 12 flower room but I still use 3 x 600w hps… like I said I’m cheap lol
The best you can do is up you exhaust. Move more air

4200K for veg, 3100K for flower. 4200K looks better to my eyes but that isn’t necessarily what the plant wants lol.
I’m not sure it matters too awful much, sunlight is 5500K and HPS is like 2100K so as long as you’re between the two you’re good haha. I’ve noticed buds are a little leafier and denser with 3K CMH than 2K HPS, which may be a good or bad thing depending on what you’re growing. For my narrowleafs, it’s perfect. I don’t actually struggle too much with heat, really what I needed was humidity management, if I didn’t install central AC this summer I’d have bought a big ass dehumidifier instead. 630 gives off much less heat than 1K but the plants transpire just as much water.

In Mich humidity will always be a problem, In Saginaw it used to feel like your swimming just sitting there
ok thanks I can take the 4200’s out of the flower, there already the veg bulbs period, My 630’s give off more heat then my 315’s but are far more intense it seems then even two 315’s.
Should I not think of 81F as my limit, I run some supplemental co2 but no clear idea of how much

I open up my tent door at lights on and close it at lights off. My tent already vents straight outdoors so there was no recirculating heat. Kept my res open with a fan aimed at it for a swamp cooling effect in addition to submerging frozen 1gallon water bottles (3x changes per day unless at work), and then kept everything else OFF in that room.
Now I’m moving everything into my basement and thinking about winter heating as it’s easier to address than this sweltering heck.
All the best!

mostly with the LEDs and cmh setup I had far longer flower times with everything and loose larfy buds vs the pure cmh where i had shorter flower times and denser heavier buds
but since im older I always think back to 1k hps

Yeah when I moved here I thought it’d be cooler and drier than central/southern Illinois, but it’s just as bad lol. I’m gonna move to Marquette one of these days. Far northern Michigan is much more to my liking. I don’t complain about much but I cannot tolerate the heat; never could. But when everyone else is bitching about the cold in winter, I’m happy as a clam.

about the only good thing here is its dry, just looked its about the most humid time of year here and in the basement in my “room” its 47 rh. everything’s down in there as the upcoming michigan trip is soon so no dehumidifier’s
And no mosquitos outside at all!

No sorry mate it was just an idea I got from the net, it was just a styrofoam fish box to hold the frozen bottles ducted to the tent. It kept temps stable but didnt reduce them by much, maybe use dry ice and get the CO2.
I’m going to have to get a portable AC unit for next summer.
