    I'm getting similar readings and a little worried myself. Already using a dehumidifier and a few silicone tubs. What's your set up... indoors in a tent? I've found my extraction and passive intake change the air so fast that I'm probably never gonna get it much lower than the humidity outside the tent.

    This may sound odd but before I purchased dehumidifiers I used regular grilling Charcoal in my space (just laid out in the open in a tub)--needs to be a small space in order to work or certain cat litters will bring it down as well if you have cats..place a pan in the room and give it a shot if available..

    What are the temps in your grow space?

    Where are you pulling your fresh air from?

    If you harvesting then more of a note for next time

    Humidity and heat are directly linked so when the temp drops off just a couple of degrees, the same moisture is still there but the air now has less capacity to hold it so the humidity climbs

    Run a dehumidifier when lights are off ( which will raise temps) or increase your heater setting a couple of degrees.

    Okay! Drying conditions are 24C with 50% humidity using a humidifier to bring it up to about 60% for a slow dry.*
