Humidity control

My tent being filled with 4 flowering plants, I can't get my humidity down below 65-60% (depends on whether I just watered and if is raining). My borrowed 500 euro dehume (dafuq 12L a day) isn't doing the job. Don't wanna have to add a 2nd dehume. Any tips?

Defoliate canopy where you can. Less leaves less transpiration less humidty. If you can't get humidty down. Just increase airflow to avoid mold. I'm just finished a few plants that had 65 percent humidity in flower and they finished up great. It's not ideal Vpd They may take a bit longer. But you can flower with high humidty. You just need airflow. Increase the size of you inline fan next grow this will help too.

That % of humidity is not ideal, but it isn’t bad either. Keep a good air exchange and air flow inside the tent and your buds will be fine.

Go to 18/6 for a start.............24/0 is so wrong for plants. There are certain metabolic processes that only occur during the dark period..........without a dark period your plants will have a messed up metabolism and any plant with a messed up metabolism will never perform to the best of its potential! Otherwise, add another oscillating fan to increase air exchange. Have it blowing over the very top of the plants, no need to have it blowing directly on them.

i cant believe, maybe you havent turned it on, ussually they can work as humidifier too. my small 3-4 liters delongi brought 120x240 tent with 5 huge plants from 99-80 to 50-55 RH. i grew most of my grows with humidity 60-70 during flower, good air movement inside and air echange prevented all mold and other issues. worst case, if nothing helps , clean bottoms first, if that dont help, start doing selective defoliation ( 2-3 leaves off a plant daily, take those who shade most, try not to touch most developed top colas leaves, anything below them can go if needed ).

Defoliate, and get some better airflow. Does your tent have those vents at the bottom? Have your exhaust fan set to overshoot so it’s runs harder.
