Hi there !
I wanted to be able to peek at temperature and humidity levels anytime without having to open the tent everytime My solution .

There are other models of course .

With a coat hanger and a little bending here and there et voila !
Nothing really fancy but it does the trick quite well .
Just set it in the zipper at the hight I want and I can read lights on or off ... I love it !
Be shure to make the salt trick for calibration of the hygrometer ( on YouTube ) ,Mine I have to add 16%
to be bullseye . LOL !

PS . The weed is Blue Dream near flushing time.



The piece of foam is for preventing light from entering where the zippers meet .
