may sound silly..

Have just started the flowering process, and my relatively cheap temperature station says humidity is around 80% at lights out.
I have a small fan blowing for 20 minutes every hour and it doesn't feel humid at all.
Should I perhaps invest in a more pricey unit or am I just stressing...

humidity go's up at lights out
need fan's and exhaust fan going 24 hr

yeah I've noticed every time lights out it gets higher so to counter that I feed my plants when lights go on so they have 12 hours to soak up/evap the most part of nutrients.
And sorry one more thing, for an exexhaust fan the bloke at the hydro shop nearest me reckons au$350..
Is this reasonable or can I get away with a cheaper setup?
My tent is 4'x4'x8' with 5 plants flowering

What is ambient humidity? If ambient is already 60+ then you need a change in your environment.

It's funny that you said this, that's exactly what my humidity was going up to with lights off in my tent 5x5x7 with two 600's...And I was running an exhaust fan 440 cfm 24/0 and it was still that high, so I had to invest in a dehumidifier....As you can see from the thermometer with my lights off my humidity went up to 84% last night. But hopefully that problem will be rectified now since I went and purchased this dehumidifier. Lol I know the numbers to my temperatures are messed up but I can see the humidity perfectly fine.

the one in tent break or you using two hang temp gauge below light near canopy get more accurate reading
mines over 40 years old and still works like new have out side of tent i'm in a basement need Lol

Might i suggest putting your temp/hygro down by where the canopy of your plants are and take a reading? Since thats what they would be seeing?

I could be wrong...

No you are absolutely right...But I can't get it at the same level as the canopy so I'm just like fuck it as long as I can get a general reading I'm all good.
