Humedad dentro del cultivo

Honestly, it's probably not going to do too much for you... I bought something like that a while back to take care of a closet in my hallway - get rid of the humidity and get rid of the smell - and it was a waste of money. If you were growing autoflowers, I'd tell you to unzip your tent and get massive amounts of fresh air in there - but with photoperiods, you could only do that for the 12 hours they're under lights... you'd have to close it back up for lights out... still, that might be one option you should consider (ONLY during lights on). You might also need to do some serious defoliation and get your fans working overtime or get more fans - anything to get that air moving all around and through that plants or you're going to end up with some fungus or other... plain rock salt is another option - if you've got room, get two 5 gallon buckets and drill a lot of holes in the bottom and sides of one of them then put that one inside the other and put rock salt inside it... the rock salt will take the humidity out of the air and the resulting water will then drip through the holes into the lower bucket which you would then keep emptying as it fills up. That's it - I'm out of ideas here - but you're right, you MUST do something! Good luck!
