PmP? Problems with RH. . .
    #9219536 - 11/10/08 07:49 PM (13 years, 2 months ago)

Whats going on guys. Foaf has a little problem. In his 58 quart FC with ~4 in of perlite on bottom, he can sustain humidity during the hours in which he is home, by misting and of course fanning. But when he works, or sleeps, or leaves the FC alone for a period of 8-10 hrs, the rh drops considerably ~65-70%. He is thinking of . . .

1). Adding bubbling wands to the bottom of his perlite tub.

or

2). Adding an airstone to a mason jar, which will be placed atop the perlite.

-Which one will prove most effective? Foaf wants to know if perlite will be as effective as hygroton or whatever its called, for the material at bottom of FC.

Also,

This is day 2 after cakes have ben placed in FC. Should he be seeing any myc growth on outside of verm casing layer? Should he be seeing any growth what-so-ever, or do the shrooms just grow like wildfiaaa ova night. thanks all. :rasta:

A PMP is supposed to have an airpump w/ bubbling wands or airstones.. It's necessary cuz there's no holes in the thing, like a Shotgun tub.. The holes ALL over a shotgun and the fact it's elevated off the ground,  is what allows the high RH, cuz there's constantly air moving thru the perlite.. In a PMP you have to supply the airflow yourself.

I gotcha J3illy, thanks for clearing it up. Foaf has a shotgun tub, but humidity still drops when he sleeps. By adding an airstone with mason jar....you think this will help this problem, at least when he is gone fro the house? Nice mycobag btw, thing looks sick, i wanna learn after this first grow.

Thanks.. I actually saw a pic of a modified PMP.. Instead of running bubble wands underneath - they had 2 airstones inside.. They weren't in the water under the perlite tho - they were inside some small containers of water, that you would have to refill.. I guess it works better for RH they were saying..

I noticed that. Can perlite be a substitute?

Just use a shotgun. Works awesome. I am able to keep my RH at a MINIMUM of 91% all the time, and spikes immediately after fanning. It is usually around 95% or so. Not as high as I want, but whatev. I'm not a pro.

To some, fallen trees are ugly. But in reality, it is the circle of life at its finest. This is a beautiful world, its time that we recognize that before its all gone."

Using perlite isn't causing this problem..

Here's the type of setup I was talking about - better than bubble wands underneath..
