Read the directions the break in is in there.

My 3x3 with the LEC 315 is running one honeywell fan on the floor, and then a walmart brand 6 " clip on on top of the tent blowing across the side with the built in ballast. Passive intake and 4" exhaust fan with carbon filter......no issues with heat and my flowering lady loves it.

I wouldn't go with anything less than a 6inch centrifugal fan. I run a 6 in my 4x4 and in summer I wish it was an 8 inch, however I have been running up to 1400w in that 4x4 vert. In a 1mx1m tent I have a 4 inch fan and that works great in that.

For sure my 4x8 is at 74 degrees with no fans. So I will probably get some simple 6" fans an call it good. No need for a carbon filters. Just solid air flow.

I would always use a carbon filter even if growing in a legal state. Plenty of people will be keen to rip off a grow.

Yea I'm only running 2 LECs 315 an I plan on adding a 3rd one in the next month or 2. That's only 630 an I will add one more going to 945W which isn't a whole lot.

RTMF, it's a light bulb lol

Mine ring occasionally. Doesn't seem to be rhyme or reason, they run fine.

Is one sitting in direct light? Deep shade? In the path of the fan? Temps can vary surprisingly widely in a small space.

Getting a third thermometer could help establish a consensus, or find a space somewhere in your house away from the lighting that's a known temperature and see what they say.

Make a glass of ice water and drop the (waterproof only!) temp probe in there. You know it's 32F, that could help with outdoor thermometers.

Like above the light is around 73 or 74 an below the light is 95, I haven't yet installed fans an things like that so that's pretty much my next step. It's working fine it just depends on where I put in my tent so I don't really know where the best place is to put it.

It's telling you to install a fan!

How far will a centrifugal fan drop the temp? I bought a 8 in fan to blow cool air into the tent, I bought a 8in exhaust to blow hot air out I'm just curious how far my temp will drop?
