veg room temp help

No ventilation? Start there.

Every time I try to my humidity drops to about 50-55% I was thinking that was to low. I already got a humidifier in the room running 24/7

50% Humidity is fine, mine is usually around 50-55 as well. I've hard that at 60% and higher it will actually make your carbon filter less efficient to the point where it won't work very well at all.

My plants grew just fine in 50% humidity. Also 85 is not super high, as long as you keep the tempurature from fluctuation more than 20 degrees, it should be okay. Mine got into the High 80's at the hottest parts of the day and they still did fine.

I would reccomend running the ventilation and not worrying about the humidity too much. Just make sure you plants have nice moist soil and that they don't dry out too much. And if you like, mist your leaves lightly before your lights turn off, they'll love it. Just don't mist with lights on and if you have to make sure the droplets are tiny, not large enough to cause burning from the magnification of the drop.

My low temp is 74.5 and my high is 85.6. My veg room is in a slideing door closet wen I open one of the door's just like half an inch my temp drops but so does my humidity. So 85 ain't to bad?

No thats fine.My flowering plants temp are between 83-86 i dont see no problems

85's not too bad at all for a veg room, a little on the high side, but manageable. Keep that ventilation running, 50-55% humidity is good. Some may prefer a little more humidity during veg, but if the air is stagnant and not being replenished it's not doing you any favours.

So I have no ventilation in the room but a oscillating fan goin full speed hung from the ceiling. And the temp droped to around 83.5. So I guess my next question is do I need to vent the room to get the old air out or is the fan good just keeping the air moveing? I got a duct fan to pull air out of the room but took it out the other day because of the humidity issue. Do you have to vent a veg. Room? The old man who taught me what I know sayd no but I'm kinda lost n he moved.......

So i have 2 of these 125 watt fluorescent bulbs in the bat wing reflectors about 16 inches from the top of my plants in my 2x5. They are still young maybe 2-3 week old from attitude. I've read so much different stuff that i'm very lost. Are those lights good in that space? thanks for all the advice
