Humidity concerns

For the past week or so the humidity in my grow tent has gone up quite abit..now it usually stays around 72 but since last night its been 76, my autos are about 3 weeks into flower..should I be concerned? As i don't think there's much I can really do about it as I don't have a dehumidifier.. the temp is always okay though..usually stays around 22 max it's been is 27

you will get bud rot or mold... throw an air conditioner in the same room as your tent. Air conditioners pull humidity from the air... might be your best bet. Do you run an intake and exhaust fans? Oscillating fan in the grow space? These can help to draw humidity out from the tent as well

Haven't got air con in the room, there's an extraction fan with filter an 2 oscillatimg fans.. only thing I can think of that might help would be to put half the plants on my spare tent under my 300w LED, would that help?

It might help... how about just leaving your tent open to remove the excess humidity?

Reference a VPD chart....if you have high humidity, raise your temps some....keep your air moving and you should be fine.
