The heat is killing your humidity, and air pumps do not give sufficient constant FAE.

That chamber has fail written all over it, I suggest making a SGFC but that's just my advice....take it as you will...

hey if it works for u then thats all that matters:2cents: i personally have tried monos, Marthas, PMP, and SGFC to which i say the PMP worked better for me than SGFC and i love my marthas just for the amount i can put inside em and they have given me some of my best pin sets

you dont wanna heat your chamber though as notahacker stated. using perilte(never tried clay pebble things) helps to wisk the water into the air which will create higher humidity and bubble wands IMO help disperse the fresh air being induced into the PMP. i currently use marthas and monos . still trying to decide which to focus on as both are pretty much set and forget other than refilling the humidifier like twice a day(once i wake up and before bed)....speaking of which lol

That seems overly complicated, and probably has a very high ROI, but you should experiment with it ET and post your results!  :cheers:

I had/have a SGFC, built to a T, but as I stated before, I don't have a closet to put it in, so it sits on top of my gun safe.  I was only getting 80-85* humidity with the SGFC, and that was with misting and fanning it 2 times a day.  There is just too much air flow in my room for the SGFC.
Also as far as heating the water, I don't control the temp in the house, as it is not mine.  I have a space heater I use when i'm home, but i'm not going to leave a space heater on when i'm not here.  So the PMP seems my best option for my cakes and pans.
On a side note, I am constructing 3 mono tubs for my Thai, PE and PES Hawaiian.  These will be my main way of growing, I just didn't want to make a tub of Pan Cams, as i've ready they do better in trays and need more controlled parameters.

That's looking not too bad. How full have you gotten it before?

How many cfm are you pushing through?

PMP humidity variation solution? [Re: RogerRabbit]
    #21117566 - 01/13/15 09:57 PM (9 years, 17 days ago)

Roger Rabbit's problem with PMP's is:  "The problem with PMPs was and is the steady-state humidity.  Mycelium wants a varying humidity level to pin and fruit properly.  A shotgun terrarium goes through these daily oscillations as the temp and humidity in the room its in changes throughout the day.  A PMP is isolated from these changes, thus develops a steady saturation-humidity level which impedes pinning and growth."

Is the solution to this just to take the lid off the PMP for an hour or two each day, switch off the aeration pump, and circulate air over the PMP with a fan, thereby dramatically reducing humidity for two hours?

Then return PMP to normal set-up for the rest of the day.  Your fruits will experience the required humidity variation with only a single tending per day.

You would think so, but no.

Opening the lid causes drastic humidity loss instead of the slow decline and rise.

Good idea tho

But please, anyone thinking of using a pmp, or hydroponics system for mushrooms... DONT!!!

Now, some mod want to :lockdance:

When I first started out I had to use an unheated area inside during the winter months. I had some degree of success with an aquarium heater in a quart water jar with pump & air stone. (pumped from outside the terrarium. To bring the RH back up I used 2 of the miniature ultrasonic humidifiers right inside the terrarium. If I would have had the misters/foggers dialed in better with the proper type timer it may have worked better.

Since then I now have a HEATED room to work in.

Nothing beats a SGFC or MONOTUB, but I had no choice at the time but to do what I had to do. It was a hassle getting it to work right. And it most definitely WAS NOT STEALTH....lol.

Did it work? In short, yes. But nothing compared to the ease and yields obtained from a properly set up mono or sgfc in a heated room.
