I have 4 white widows in a 3x3x5 and I’m have a problem with my humidity right now can someone please help me? it’s climbing up to 80% and low 75%. My exhaust fan is at low/medium speed, would speeding it up help it to keep it down or should I keep the tent door open? And is my temperature/humidity gauge in the wrong location?
Is this way ok
I usually hang mine at canopy height. If the tent is in your house, I have lowered humidity by opening tent and running a box fan at the door to the grow room to draw air from the rest of the house. Some people end up using a de-humidifier
I hang mine at the height of my canopy and a few feet away from the plants. If you set it on the soil you are going to get high readings from catching the evaporating moisture from the soil. I also keep fans blowing air up through the canopies to keep fresh, drier air moving through them.
