Martha and humidifier
    #19480751 - 01/27/14 10:53 AM (10 years, 11 months ago)

After growing cubes in couple of Marta's I found out that you don't need a ultra sonic or cool mist humidifier.
All you need is a tub with water and a heater inside set to 26-28 degree Celsius.
With that i had RH to constant 99 % and after misting it will drop down to 85 for 5 minutes and then rise again to 99 %.

So why you people use humidifier. I know mushrooms love mist, but i found out they only need a hi RH to grow well.
Does anyone knows what are the benefits of using humidifier against tub of water with heater?
Don't get me wrong i try both and can't find single thing that prove humidifiers do any better.

can someone enlighten me please?

Thanks in advance.

sounds like you have a really shitty hygrometer and the readings you are getting are bad anyway. They're not calibrated for the temperature swings either so you can get fake 99% all the time.

I'm a newb (As I say before all my posts.) however, there are some things I 'think' I have learned so far.

1) RH isn't necessarily what is important I think. RH is important I think because it prevents your substrate or mycelium from losing moisture to much and decicating. what may be equaling important to promote pinning is hydrating and then drying by FAE (Fresh Air Exchange) and changes in the microclimate. in my mind anyways, may setup a type of ebb and flow exchange within the substrate which promotes growth and maybe even nutrient exchange and pinning. This is why I believe the goal is to spray THEN fan. instead of fan, then raise RH back to X%

2) as mentioned above hygrometers give fake readings.

3) a humidifier ups the RH, but isn't always needed, you are surely correct. RR has shown this with the SGFC when it is done properly. the perlite creates a ionic exchange (with its micro climate) that exchanges moisture by creating a difference in air pressure. this also creates FAE. the same effect can surely be done in a green house, and I have seen some mention troughs with perlite, or even channels running with stones/etc and water flow, to do the same thing. we know that water particles make air heavier, in the case of a mist, that falls down and lighter air goes up creating air movement, steam being excited air molecules and energized I think wants to go up....when ti cools it then falls down (welcome precipitation and rain.) so your idea of the water and the heating element makes sense.... the issue I think is the amount of energy required and used and what is more efficient. Not to mention when you start using heat elements you effect the temperatures inside the chamber and you then have to control that possibly if outside the range of the strains you are growing.

short term ways my mind would think of it anyways.

i like my rh to hover around 90-95 at the most in my gh and you can't put a bucket of water on a timer, they don't need a good rh to grow well they need a good rh because they have no skin and lose moisture to the enviroment very easily, they need good fae to grow well

@ bodhisatta

really man what you say about my hygrometer?
Touch my mama but don't touch my hygrometer :laugh2:

No really i have digital and analog one, and they show the same and analog is calibrated with salt and boiling water. So when we get that out of the way.

@ RandomFX

nice post but the topic is RH not FAE.
Maybe i mislead you. When i say  "I know mushrooms love mist, but i found out they only need a hi RH to grow well."
I talk only about RH here.


@ cronicr 

Again I am talking only about RH
and without the Hi Humidity they wont grow at all :wink:



did any one try this at all.
i had rh 95 on digital and 100 on analog in weed tent 50x90x160cm 5 floor's
with one aquarium heater 300w set to 26 or 28 Co


i was hoping someone would say something like yea they do love hi HR but mist gives them something more a boost a better grow or something like that.

They breathe, fresh air gives them a boost. RH like cronicr said keeps them from dying. They need the RH atmosphere because they don't have epidermis. It's not that they wont grow at all without RH it's that they die without it. FAE is the boost you can give the more FAE as long as it doesn't kill your RH is best. So that's why we use humidifiers. So we can get RH with the FAE boost, usually air movement means lower RH, but just a pan with a heater means high RH with no extra FAE which is less optimal then high RH with high FAE. Just sayin.

:whathesaid:
they don't grow from humidity they grow from pumping there cells full of water which they get  from the substrate
and yes 5 years ago aquarium heaters and bubblers were used in one of my gh's they are hard to dial and there are much easier/more effectives methods then that though

i'll try make this simple for ya, if your gonna go that route i would cut slits along the sides of your gh and run a fan in the room for fae, whater you decide to do for rh just be sure you have nice beads of moisture across the surface of your substrates, as air passes through it creates evaporation off the surface of your substrate(key pinning trigger) and that evaporation in turn gives you 100% humidity on the surface of your subs at all times so no matter how much you want this to be only about rh it just can't be...it's a balancing act

@ cronicr

Nicely put out there. It is all about balancing like life itself it is.

This is my setup from couple of years back.

http://www.shroomery.org/forums/showflat.php/Number/13507702/page/2

going with the saying easier is better i thought
All that extra parts for humidifier maybe i don't need one.
I want to reinventing this martha with just water and heater for RH and one ventilator  for FAE.
Do you thing it is possible?
I mean is it insane in this hi tek time to do something prehistoric, almost barbarian way?
