PMP HELP
    #9319970 - 11/27/08 01:12 AM (13 years, 1 month ago)

Well I made myself a pmp.. It is 15 by 12 and about 16 high..  It has 4 inches of geolite and about 3 inches of water with a 40 gallon fish tank pump and two 10 inch bubble wands in the bottom..  The problem is I can't seem to get the humidity over 90%, there are no air holes I fan every 2-3 hours.. So can any give me any advice on how to get the humidity up..

Perlight has a larger surface area then Geolight, therefor produces more humidity. getcha' some of that :thumbup:

PmP doesn't use perlite to humidify it.So thats wrong advise unless we was talking a different setup.
What type of hygrometer do you have?Digital ones are really inaccurate in high humidity.Don't fan and see if it changes.
Also try less water so you have more surface area.2 inchs is plenty.
Mine has four 1/4'' holes in the lid So I dont have to fan.I still fan once or twice a day though since I like misting the little guys.

It's OK to use perlite in a PMP! It's actually advised to do so. Only use geolite if you can't find perlite.

It seems to me the PMP was designed before perlite was popularized.  Otherwise I think it would suggest to use it - cuz it will work better for the purpose, and it's cheaper than Geolite.

Its not advised to use Perlite in a pmp.Although it might be OK too.Use Geo-lite or Hydro-ton or even small lava rock.Geo-lite,Hydro-ton can be used many times ,Perlite cant.
Heres a link to the tek.

that post is 5 years old. things have moved on from them. While lavarock etc can work. Perlite still performs better at humiditfying a terrarium. You can use it in a perlite, but no standing water. Just put your airstones in a cup of water.

Ditch the bubble wands-get airstones,the airstones work alot better,put three 12 inch airstones in your PMP,each airstone should have its own 50 gallon air pump....if you do this,I promise you that it will stay 99% humidity constant

They have?I dont see no tek saying to use perlite in this setup.Why would someone use perlite.Its non usable.The OP says hes using the PMP which is the poor mans pod Not the shotgun terrarium that you idolize.;)

While it may be  OK to do so I'm going to say its not advised... there is a different principle going on here than perlite, there is a whicking effect from the stored water blow the surface, thus humidity. Perlite is mostly water from inside each kernel.

The air pump is also for air exchange and not primarily humidity. The original design (unknown to me, the company went under) likely placed the tubing under the water for a combination of increased humidity and a filtering effect on the air supply. As air bubbles pass through the water any particles get stuck to the edge of the bubble and it picks up water vapor.


Now, if you want to go by age. I would have to say that's tried and True more than old and weary. I can almost guarantee that the shotgun terrarium is more than five years old... And hasn't changed a bit.

WTF!  where do you guys come up with this at?  Geolite is used for PMP's and perlite is used for shotgun terriums.  End of story!!!

im with nw_shroomy on this one.

Pmp's are meant to have standing water.  start reading before you post.  you guys have some thick ass skulls when it comes to anything other than the "shotgun" fc

I have a PMP myself... the principle in a shotgun and a PMP is basically the same. Air flows from bottom to up, picking up water from either geolite or perlite. Only the means to achieve this are different. One uses an air pump, one uses the laws of physics or something.

I'm using geolite in my PMP but if you buy me some perlite I will prove to you it can be used in a PMP with no difficulties.

good luck getting perlite to stay submerged in the water.  pmp's use water. like i said earlier.

if yor using perlite with no standing water and bubblestones beneath it it's just a shotgun fc with bubblestones.

You don't have to fill the water level up past the perlight level... and nw_shroomy, you make it sound like perlight is like a one time use thing. Its a crystalline product, a mineral. It doesn't degrade ez... I've used mine many many many times over and over. Perlight trumps geo. Yes the guy that originally thought of a PMP used Geo, that doesn't mean better ideas can't/wouldn't be implemented over a span of 5 years. Replacing the Geo w/ perlight would only benefit for RH. ...and yes, we know its not a shotty...

How do you clean it once you get spores all over it as I see you let your shrooms open all the way?How do you dry it for storage in between grows?:confused:
Perlite Doesnt trump geolite in a PMP setup.:crazy2:
If you can point out a TEK that has replaced the PMP with perlite Because its more better in a PMP than geolite then Ill be the first to shut up.

Ok every sorry just now getting back on..  Well I am using a analog hydrometer.. And I am happy to say my humidity is now at 99%  I think the problem was I was just being inpatient last night and not giving it enough time.. My pmp has roughly 4-4.5 inches of geolite and the water comes to about 1-1.5 inches from the top of the geolite.. I have 2 10 inch bubble wands in the bottom as stated above, and a 40 gallon fish tank pump..  Also I have drilled 2  1/4 inch holes in the lid for air exchange do you think that is enough holes of should I go with more ??

I personally never got spores on my perlight. I bought lil aluminum loaf pans, and cut off most of the height of the pan walls so they were more like a plate with short retainer walls to keep a thin verm lair contained:



Since perlight is a crystalline product, it doesn't harbor many contams when its solo. I never seen anything grow on it. After I successfully completed my first grow (PF Tek) I abandoned my 1/2 ass shotty for a long time... (My shotty wasn't constructed like a true shotty) just kinda pushed it in a corner and forgot about it. When I came back to it some time later the perlight as all dry pretty much resembling when it came fresh out of the bag. I just laird it out on a large cookie sheet and popped it in the oven for 30 mins on 350 when I decide to re-use it again for random cake experiments and shit.

Why does a whole new tek need to be written up when only such a small detail is changed? When used solo, compared perlight will produce higher RH then Geo. Just cause of the fact that perlight has the largest surface area.

I think more people should advocate more common sense, creativity, innovation, and originality. Apposed to dangling from some other guys dick, waiting for them to tell you what to do. Yes there are some guidelines set in stone, but if you don't try to think outside the box, how can this hobby ever evolve ? You can obviously look back to info from years ago, and laugh at it, hysterically in some cases... and we can thank creative, innovative, and original people for this evolution.

i used geolite the whole time i used a pmp with great results.  i had great humidity the whole time.  you have to change the water every couple weeks so that was sort of a hassel. but all in all it works just fine with geolite.  and how can it be a pmp with perlite if there's no standing water with bubble stones pushing oxygen up through the bottom.  like i said it would just be a shotgun with a bubble stone it s not a pmp.  you guys are making this way more diffucult for the OP.

OP- i used two 14" bubble stones in the bottom of my pmp and also if you look at my pic earlier you should construct something like the tubes i have to get your cakes up off the surface of the geolite it will help keep your humidity up.

I have to say it again, because apparently nobody is listening.



The pump is for FAE

NOT Humidity


You MUST match the air pump with the size of your tub or it won't work.

Edit: as for maintaining the water in the tub, any chemical that will not evaporate into the air into sufficient quantities to harm the mushrooms can be used to keep it clean. Bleach, Iodine, H2O2, are whats readily available to me, humidifier anti growth agent might work awesome but I will have to check the MSDS before I can make a recommendation on that.
Ask for details before trying any of those chemicals people btw.

The pump is for FAE

NOT Humidity


You MUST match the air pump with the size of your tub or it won't work.





your kidding right?  the stones push moisture rich oxygen into the air witch aids in humidity.  it's the same principle as a humidifier.  ugh.

Yea the pump is also for RH in a PMP - cuz there's no holes in it like there is w/ a shotgun.  Shotgun lets air in from underneath which comes up as humidified air.  PMP pumps air in which comes up as humidified air.  In both concepts it's also fresh air.

Someone should do a PMP test w/ the same exact tub and pump - and use geolite vs. perlite, then post results.

The air pump is also for air exchange and not primarily humidity. The original design (unknown to me, the company went under) likely placed the tubing under the water for a combination of increased humidity and a filtering effect on the air supply. As air bubbles pass through the water any particles get stuck to the edge of the bubble and it picks up water vapor.




Like I said, Nobody listened to my previous post.
Oh, by the way. I have a PMP that works just fine with no bubbles. I understand the principles of the poor mans pod design.

again, how would you use perlite?  the perlite is all going to float in the water.

How is it gonna float?  If you put 4-5" of perlite in a tub, then add a couple inches of water, how exactly is it gonna float if the water line is below the top of the perlite?

While it may be  OK to do so I'm going to say its not advised... there is a different principle going on here than perlite, there is a whicking effect from the stored water blow the surface, thus humidity. Perlite is mostly water from inside each kernel.




Again referencing my first post.

You can have standing water with perlight too... there is still big enough gaps between grains for air to pass through. personally if I used perlight in a PMP, I wouldn't have he water level flush with the perlight level like with geo. I would have water level 1/2 way up the depth of the perlight. The wands/stones would still be submerged in water, and you would get the benefits of both humidification types. Along with the idea that the oxygen would be rising till it escapes out of the top ventilation holes, pushing the Co2 out. I'm not saying this is the way it has to be done, just a nifty/smarter choice imo.

Since the air is passing through the water, the air bubble is filled with some humidity vapors. when it reaches the water surface area, it releases the humidity into the chamber, delivering FAE, and rh...

Why does a whole new tek need to be written up when only such a small detail is changed? When used solo, compared perlight will produce higher RH then Geo. Just cause of the fact that perlight has the largest surface area.



Couldnt find one?Maybe because It would no longer be a PMP?The OP posted he built a PMP not a freaken tub with perlite in it.
