wow! you really can run it that strong? it must be the elevation here. i'm at 0.8 in full blast mode in bloom and .2 of that is my well water. and i still got a tiny bit of tip burn.

Or maybe the RH. What is the RH in your grow room? Mine's at less than 10% in my veg tent, and 11% in my flower closet that's sleeping still right now. I know it's crazy low. What makes you say elevation?

elevation in that the closer you get to treeline, the slower plants grow. i'm almost 4000 higher than Denver.
my veg RH is low like you but i run a small dehuey during bloom since it gets up to 60% with all the foliage inside.

I'm at like 9000 feet in Conifer. I had to run a dehumidifier sometimes before I started to exhaust outside. Now it's always crazy low. I could set it up to only exhaust once the RH gets high, but I just leave it running 24/7.
Why do they grow slower? Does it have something to do with less air pressure, kinda like how it's harder to breath, and how it takes longer to cook stuff? I'm curious now.

oh hell, i didn't know you were up that way. i go up the back way to 285 to get to denver. i can't tell you the last time i took 25.
i actually suck cool air in to keep my room in check. it's only 12 sq ft though. not sure how big your going.
from what i know, the lower O2 content causes slower growth. where it gets to a point of treeline where it's lower than what trees need, they dont 'grow. that's the story i'm sticking to.

Ya, I-25 sucks, but it's nothing compared to the West Coast freeways. Seattle is a nightmare anymore. Where are you at?
I just have a 2x4 veg tent, and an ~3.5 x 8 ft flower closet. I have one 6 inch fan sucking air outta my flower closet and outside. Another 6" just blowing back in the main room, and a 6" intake fan for that closet. Then I have a 4" intake and 4" exhaust for the veg tent.
Since I ran that one exhaust outside my humidity has dropped drastically, and I don't even need to use the expensive dehumidifier I bought anymore. It's actually a bit too low.
Also I did some research on the elevation thing. Not all of what I read applies to indoors, but the lower air pressure and lower CO2 makes sense. So does the lower RH. Outside the ground warms up slower at high altitude so that makes sense. But the Sun's stronger up here since there's less atmosphere so they should grow faster outside in that respect. Interesting. Here's one of the things I just read.

according to this, it's been studied since 1900's and they still don't know:Ya, I-25 sucks, but it's nothing compared to the West Coast freeways. Seattle is a nightmare anymore. Where are you at?
