Looks like you can't seem to put your babies up for adoption either. I think that isn't an uncommon malady. Sorry to hear about the heat stress.....How large is your intake fan/duct? Where does it get its air from? I don't have any direct experience with this because my grow room gets good ventilation and if I need to cool it off I just open the window. Anyway, this may be extreme but if you can bring in cold air from outside that might help_or from another room or from the same room outside your tent that is air-conditioned (if you can fit buying one into your budget_and have room for one of those floor jobs or can install one in a window. Last grow I had 5 gallon buckets and the humidity went way up so I had to buy dehumidifier. Got a large one and it works great_they also had air conditioners that were about the same size and price. Saw them at Home Depot, its not small though, about 6 cubic feet. A friend has an intake fan that pulls air in from outside_ it's often below freezing here at night now so he has it rigged so it turns on when the temp gets to 80 and shuts down when it gets to 70. In a way just like your dehumidifier. I can ask him about the setup if you'd like. Good luck, hope the problem gets resolved!
