So I run TS1000 18'' over the canopy and It's getting way too hot (around 85F). I'm at day 30 veg and the light is set at 75%. I can't think what will happen when I turn to flower and the light is at full power. How do I keep the tent cooler? Is this the optimal position for the oscillating fan? Should I place another one or should I buy a better exhaust fan?

Cooler air from outside the tent (intake air). Air conditioning unit.
Well I guess my exhaust fan isn't strong enough because the outside air isn't warm at all

What are you using for an exhaust? How big is the tent? What's the temperature outside the tent?

Lower your clip fan so it pushes cool air from the canopy to the top. At the minute it is too high and is likely only circulating the led heat in the upper space. If your thermometer is in direct light it will also give a higher reading. Place it under a leaf at canopy height to get a more accurate reading.
If you already have an extractor, even only a 4 inch, that light is only 150W, unless I got that wrong. It should not be pushing you up to 85f. Try and get a more accurate reading, 80f at canopy level is fine.

I thought it's the top leaves' temperature that is concidered most important. However yeah it makes sense cuz its only the top few leaves and not the whole plant

114 CFM should be more than enough. Are you running it at 100% 24/7?

If the thermometer is in direct light, the plastic will begin to heat up, and that will increase the reading, since the plastic will be warming the air around it. Just under the top leaves is where you want it, and make sure there is nothing else around the thermometer to interfere with the reading. The same applies to humidity, it will always give a higher reading if it is near a wet pot or touching a leaf, since they will most often give off more moisture than is actually in the air.

Open a flap on the tent so air can get in?
I figured it. That was radiant heat. Not the real heat since my thermometer as you can see on the picture is face up on the scrog net just below the lights. Moved it under the leaves and now hope for better temps

Open the tent from the top corner if you must.
