i actually had the same ? about where to position the dehumidifier but i never looked into. i would assume that the more humid air would be heavier due to more H2O but i cant say that for sure. your temp device doesnt have the RH%? i thought i had seen it in the previous posts but i could be mistaken. you should find a cheapy temp and RH% device so you can figure out where the % is. from my research the ideal range is 40 to 60% RH during flower, but it seems like your in the 80 % or something if you were getting moisture on the inside of the cab. always good to recycle! super cropping is basically taking a branch between index finger and your thumb and popping the main canal that runs through the stem. this causes stunted growth in the area and allows for a knot to be grown where the popping occured. it allows for the rest of the plant to catch up and produces a stirdier stem. ill get a pic in a few days and show you an example of where i supercropped and the plant recovered. ive even had some where the branch is completly sideways and floppy and still survives. MJ is very strong willed plant and can take alot before giving up on you.
edit- i had a chance to grab a couple shots for u
