I have used one just at night time and I just set it at 50 relative humidity so it will turn on if anything goes over 50 and I hang it from the light bar at the top of my tent there’s a real cheap one on Amazon for like $25 that I bought it works pretty good keeps my 2x2 under control, cheap and works has no light for leakes make sure the one you get has no lights or tape over them
