Yea I never had problems with a rH range of 15% – 70% lower towards flower finish. IMO 50% rH 24/7

If you gotta add moisture small fan blow’in on water cheapest, or like me spill shit all over the place and make a huge fuckin’ mess. Watch out for moisture on outside windows :talking

aha maybe tis not the low humidity that affects my yield. is there anybody out there getting killer yields with an RH of less than 45%?

In low humidity (dry air) Leaves form narrower to reduce transpiration (natural evaporation), Leaves will be broader in a higher humidity space, increasing leaf surface area and trichomes, and so weight of manicured bud.

I always believed that the battle is having as high a humidity as possible, making the leaves breath as efficiently as possible, too high will cause mold issues though.

You will lose moisture if the room is too hot, increasing your ventilation may increase your humidity, as cooler air holds more moisture.

If temperature isnt a concern then keep piling open containers of water into the room.:smoke

In general, plants love humidity but they can do OK in low humidity too provided that they are healthy and past the seedling stage. During times of plant stress like botched transplanting and other grower screwups, it may be advantageous to raise your humidity, especially if its below 40%.

The ultrasonics are the best and quickest. Dont get a bigger unit. You must seal up the room you are trying to humidify really good or the humidity will escape to less humid areas. That is for sure the reason it doesnt seem to be working for you.

Not true.
We gotta X-plain that some more.

“Because moisture (water vapor) is part of air (mainly nitrogen and oxygen, with other trace gases including water vapor), I hesitate to say that “air” has any temperature-dependent “capacity” or ability to “hold” water vapor. What I can say is that water molecules are constantly changing phases (solid, liquid and gas) and that the rate of change is temperature dependent (there are other factors involved as well). When there is more energy available (higher temperature), there is a net evaporation (more molecules evaporate than condense). When temperature decreases, there is a net condensation.

So in the case of cloud formation, it isn’t that rising air cools and has less “holding capacity” for moisture, but rather that in a colder environment, there is net condensation, allowing for the growth of cloud droplets or even ice crystals.”

On topic ‘tino I don’t think humidity is your culprit. Please take a picture of a leaf and post it. nerd

running 9 600w lights in my flowering room and the humidity is dropping to 28% at times with terrible effects on my yields i tried using an ultrasonic…
