I am testing the Boveda large Humidipak 62. They are in (2) 2 1/2 gallon jars. One contains Centennial Seeds Roughneck and the other is BOG Sour Bubble. There is a hydro meter in the jar with 24hr hi-lo readings. This should afford a fair monitored test. The meter reads 25% at the moment as I just brought it in from the poly. Will give it 24-48 hrs to stabilize.
