Hey man, just so you know, most hygrometers suck and aren't reliable. If you want a decent one go to a cigar shop and get one that can be calibrated. But really, since you built the shotgun correctly you shouldn't have and rh% issue, so don't stress if that thing isn't reading as high as you think it should... If your perlite is moist and your tub is raised up, you should be golden. Also, a proper built fruiting chamber doesn't really get condensation on the walls, that's not related to humidity... it's just was it is, condensation... Which forms when it's warmer in the tub than in the room it's in... With a proper chamber it gets enough air from the room to keep the chamber the same temp, which doesn't cause condensation. Just clearing up some common misconceptions about humidity... Cakes look great by the way! Can't wait for some pin porn! Haha
