Hello everyone, I have a arduino uno controlling my fans and I was wondering if during the dark period, the tiny leds on the arduino will interfere with the plant. They are not that bright its 1 small green and 1 small red. Should I enclose the arduino or could I ignore it? Thanks for the...

Ups, I'm about to finish my cabinet with 2 intakes and 1 exhaust. Gonna have to improvise, adapt, overcome.

Negative pressure won't help with smell because you are always venting out and I'm not sure if the plant is going to like negative pressure... Photosynthesis and all. But I'm a newbie so don't take my word for it. Just my 2 cents.
