OVERHUMIDITY? is there such thing?
    #3242221 -

Question:
Im using a cool mist humidifier and a bed of perlite in a small styrofoam grow chamber, it appears it is very very damp within the chamber and so damp in fact - that theres small water droplets on the cakes, im wondering of that is going to inhibit pinning in any way? is there such thing as overhumidity? as you know overhumidity will cause condensastion and thats what this is - condensation all over my cakes in little droplets.

Does this pose a risk/problem or do the shrooms enjoy having water droplets all over them? Is there such thing as too much humidity?

Thanks,
irie420

Droplets on the substrate is never a good thing. Are you misting? The cool mist should not be the cause of this, as it is mainly used for air exchange.

With cakes you want as close to 100% humidity as you can.

Yes, that's why the old PF-Tek had a drip shield.  This will cause aborts the way it is now.  Try taking the cool mist humidifier out and use just perilite.  I'm sure others will tell you the same.

You don't have a big enough grow chamber to be using the cool mist humidifier IMO, unless you were to run it through a system of coke bottles like old teks said.. still the Perlite should give enough humidification by itself if you have the water in it.

The drip shield was used to mist on. If you just mist the sides of the terrarium, you do not need one.

I bought a cool mist too to mess around with, but it actually sends out very small water droplets. It's probably not a good idea to put it straight to the chamber. You can remove the large water particles using series of bottles or better way would be a long of hose/tube to make verticle loop like an upside down U so that the condensate will drip back into the humidifier.

As far as humidity.. I think the humidifier puts out way too much air flow to give time for perlite to work. In addition to that, I think oversaturation(getting it wet) of perlite keeps perlite from actually increasing the humidity to desired level. So, I think you are defeating the purpose of perlite when using the humidifier with it. I really put the humidity away and bought air pumps and wands. It worked out much better for me.

I might be wrong in some things here, but it's what I think and suggest.

You do not use the soda bottle tek with a Cool mist. The cool mist will keep a terrarium at a constant 90% humidity. It is mainly used for air exchange.

Now an ultrasonic, you should use the bottle tek with =)

The water droplets from the coolmist is really noticeable. As a matter of a fact, it says right on the box, "visible moisture"

Citric could be right, though. It could be low enough to keep the water droplets from forming on the cakes.

That is why when you run it you have around atleast 2-3 feet of tubing between the terrarium and cool mist. It will get rid of the actual water in the air and just push out the humidity.

I'm pretty sure the tubing has to be longer. I was messing around with 12mm OD/11mm ID hose at 3 ft high verticle(2M total) loop and was still getting water droplets to form. Didn't have any cakes so I can't say there would be droplets on the cake.

Sam

OOHH.. wonder if I can put it under the layer of dry perlite...
Give me few hours.. I'll let you know.

Use 1" OD 3/4" ID tubing.

Okay. I really didn't want to, but i cut my hose in half. I figured better to let some water in there intentionally so the perlite can do its thing. I only have 1" of perlite, though. That's all I have until the sun comes up. If this works, I'll have room to birth all my jars. I was going to run out of pods when burma strain got done with colonization.

I'll let you know in 30 minute. It's ugly but real simple mod.

1"? That's a hose. That shouldn't even be called tubing. If this doesn't work, I'll get it and try it in the morning. I don't think I need that much flow, though.

Hey, Citric, if this works, how many pods do you this 1 humidifier can run? I mean it puts out at least 10 times as much air flow as the two of my air pumps combines...

Someone please remind me to update this tomorrow. I keep peeking at it and it's really working against my goal of maintaining patience. I'm just going give perlite a chance to absorb some moisture to do its thing, so I'm gonna put it in the kitchen and forget it exists.

Gonna go peek at the cakes now.

The problem with using a cool mist alone on cakes, is that it does not put out enough humidity.

You should add some water to that perlite. It will give the added humidity levels that you need. The cool mist will give you the air exchange you need.

Air exchange = Thicker fruits
Humidity = Bigger fruits

I was thinking the water droplets that usually form will be enough for perlite to kick the humidity up. I will need another pod or 2 in a week, but for now, I'm just experimenting since I bought the damn thing. I also thought maybe I can push the hose in a bit farther into the pod so a small water level can be maintained inside the pod for perlite. It's a lot of water it's suppsed to use. It's gotta go somewhere you know. If this doesn't work as is(hose to the bottom) I'll try pushing it in a bit. If not, oh well.. guess I can always save it for the casings as long as no big water droplets make it through the perlite layer...

Sam

Hey! Stop giving me ideas! I have enough experiments going on.

That worked very well for an old friend =)

Btw, there was no perlite or nothing in there. Kept constant 90% humidity with constant air exchange =)
