I’ve found in the middle of summer a frozen water bottle inside the intake cools her down a fair bit just watch for excess humidity but sometimes ya gotta do what ya gotta do aswell looks a bit longer than 3 weeks away to mate

You could try to move the entire grow to a cooler area or with air conditioning.
If you're running 18/6 or 12/12, you could schedule so that the lights are off during the hottest part of the day.

I’m in East Coast, Hot and Humid, sweaty town.

What worked for me is to put a small ac window unit in the room with the plants. Shut the door.

Hope this helps

They're Big enough to handle some stress remember stress isn't all bad (creates defense mechanisms, terpenes/oils) can you back your lights off or up? It looks like you know how to bring a crop to finish, but missing a vital piece of environmental control, Walmart has150.00 A/C units, You'll need it for drying your crops too. If Your a Cultivator you cant live without an A/C unit. My Plants all grow at night, timers turn on at 6:00pm. My Grow room A/C runs on low/cool with them. If Your in it for real, you need the tools - If you cant adjust lighting/heat make sure they have water, they'll manage their own stress. good luck -

I was having a similar issue, tried all sorts of combinations but wasn't having much luck. Besides changing the lighting to come on at night, the most effective thing I found was venting the dehumidifier outside of the tent, this made things much better. I've now vented the aircon directly into the tent, so it's even better again. Initially I was hitting upto 30°c but after venting dehumidifier out I was around 27/28°c and now 26°c with the ac funnelled into the tent.

Well, I don’t use any reflective surfaces, my plants rip, it’s just a suggestion to get you temp down. It is always about what you are comfortable doing. But taking them away for a few hours and checking temps to see if it’s worth it to remove is a pretty easy little test to run.
