Ultrasonic Humidifier

[BirDMan420]

Hello everyone so I’ve been using a Ultrasonic humidifier in my tent which was a great purchase but have one question. I am in the flowering stage and now I’m wondering is it bad to have the thing misting on my plants? I want to say the answer is yes? It’s a warm and cool mist, and I only had the warm mist on during veg, now that it’s in flower I have it on cool. But should I put it on a chair above the plants to mist. It does fog and go into the plants and I don’t want any bud rot to occur.

Yeah if it’s fogging and getting on the plants it’s a good opportunity for bud rot and mold

What is your room humidity? Unless it is really out of bounds, I would be careful about using any kind of mist on your buds. If you need to raise humidity without mist, and you have room, a container of water with a towel hanging in it and a fan on the towel works reasonably well, and should bring RH up about 10% or so.

Can't tell from here. You need more expert eyes than mine for that one. Good luck with it.

It may be. How's your VPD? What is your temp and rh?

Keep my VPD from the 1.1 - 1.6 range. I accidentally left my humidifier up one night so it was 55-60%rh at 68 degrees :/. But typically I keep the temp around 72-78 depending on how hot it is and the rH from 40-55, 55 being the highest point when I’m not home to fix it. I going to get my dehumidifier going to keep my rH at 40.

But question if I keep my VPD in the green zone will mildew still happen? Should I take preventative action toward the mildew and still aim for 45-50% rH

Do you have a fan in there circulating air around too? 40-50% humidity shouldn't typically cause issues, especially if you have good air movement. Either way though, definitely dont want a mister or humidifier blowing directly onto your buds

I have a fan blowing on the canopy and one pulling air out, but if I raised my humidifier above the plants and have it mist will that be okay?
