Jak udělat ideální vlhkost při květu?
Acerplugstarted grow question 9mo ago
How to achieve ideal humidity during flowering? I'm at the beginning of flowering, so the humidity is still fine, but in 3-4 weeks it will be a problem. When the lights are off, I have around 65% humidity in the tent, but in the room where the tent is, I have 52% humidity. I have the exhaust set to 80% and the fresh air intake on.

In the early flowering stage, about 60–65% humidity is still fine, but in 3–4 weeks, when the buds are denser, it's better to be around 45–55% RH to prevent mold from appearing. You have about 65% in the tent and around 52% in the room, so it's important to get more air from the room into the tent. Let the exhaust run nonstop, ideally stronger at night, open the intake as much as possible, and provide stronger air circulation in the tent to avoid pockets of humid air between the buds. Water a few hours before lights out rather than right before. If that isn't enough later in flowering, the best solution is a dehumidifier in the room where the tent is. Right now, your values are fine for the beginning of flowering, just be prepared to gradually pull the humidity closer to 50% in late flowering.

Increase the dehumidifier in the room and the exhaust from the tent.

It could be the amount of ventilation you are using inside of the tent, your RH should be lower near the light while the rh is higher on the pot height. If you push more air around in the tent that should help with lowering your rh to 60. Also maybe start your heater in the room that will help with 1-2 C and will lower your rh a bit more :)

You may have to get a dehumidifier. But with the room the tent is in, being so low, you should be fine and it should be dropping the humidity to a similar %
Some small things, are watering in the morning so it has time to even out.
Also if possible, you can leave your tent door open and it'll help with the humidity to be closer to the room.
But also I run based on vpd and I will run anywhere from 65-68% rh during flower if the temps are up above 82f
I haven't had mold issues while chasing vpd even though the humidity rises higher than what we were taught before.
I've had better results by not lowering the humidity throughout flower.
It's only concerning to me if the temps are low and humidity is high.

Freeze a few water bottles and place them in the tent, in bowls to collect the water. The humidity will condense on the outside of the bottles. Or simply use a dehumidifier.
Keep a few bottles frozen at all times and replace them as soon as it gets warm. This can lower the humidity by 10–15% but also the temperature a bit.
Imho 60% is fine during flower, if the plant isn't too thick and well ventilated.
Also try raising the temperatures. You want to be at 1.2-1.4 VPD in flower.
19°C is at the lower ent but still okay, it does not match your humidity though.
You can google for a VPD chart. If you can't find it, shoot me a DM.
Good luck! 😘

A dehumidifier will help. Having it dryer during flowering will prevent mold/mildew and encourage better trichome development. Since you dont have one, water when the lights come on when the plant will use it, not just before lights off. Defoliate a little. Use 100% air exchange. These tips will help until you get a dehumidifier.
