Too much air / Too little humidity

People seem to get so bent out of shape about low humidity? Low humidity is not a bad thing at all, running under 50% in veg or even 40% does little to the plant other than speed up the metabolical rate allowing for more uptake of water and goodies. The problem is the grower not noticing the increase and starving them, this is where most growers have the issue and don't even know it!

My flower room right now is at 25% and if I could get her lower I would.

Air movement is the other issue with low humidity, wind wicks moisture off the leaves, so you only need minimal air movement. We all know already the leaves should just wiggle and not be getting ripped off by the wind. Don't blow directly onto the plants and you are fine.

Don't worry about low humidity, its the opposite that brings DEATH.

I've heard mixed things about low humidity. I had only recently transplanted my babies so its hard to say if it was just shock that they came out of or if raising the humidity truly helped

In my experience, plants of all kinds are stressed/shocked to some degree by a transplant, no matter how gentle. Elevated humidity reduces water uptake and demand on a plant's root system which is at least partly why it helps plants that have been disturbed or are re/establishing roots. Many parts of the southwest U.S. will drop into single-digit humidity levels for months during the peak of summer and guerrilla grows still happen there as long as the plants have water. It's not a problem for established plants.

i read you want the air blowing on the plants to build a good root and stem structure, no? not hurricane winds, but i have 2 5" clip type fans in my tent, and a 6" 250cfm booster for my intake at the bottom of the tent. im still dialing in things, so stuff might get moved a bit. veg tent temps are 77* stable, trying for 75* w/440 cfm 600w ac hood fan (full blast), 8" 500cfm exhaust booster fan 100%, 6" 250cfm intake fan 100%. no plants, still testing.

Good you mentioned that...this is when and only when I worry about my humidity, little girls freshly cloned or planted have little green so keeping that is important, a dry enviorment will wick moisture from them litle girls quick. 60-80% is where I like my clones at for the first few days of their new lives.

Air movement is definetly required for proper transpiration, In young cuttings or seedlings air movement definetly helps in "hardening" the little plants and that includes the stocks and stems.

Genetics play more of a roll than the wind when it comes to hadryness of your strains, leaf size, and of course stock thickness.

You will more than likely find you will want to lower the humidity as summer approaches, at least thats how it is on the east coast. Especially during flowering you want to maintain less than 40% to avoid mold.
