Question about humidity from a noob
    #26825246 - 07/15/20 01:22 PM (3 years, 6 months ago)

I am using the PF Tek and I put my cakes into my fruiting chamber. At first the humidity was at 95-99%. After a few days it is now pretty steady at about 83%. Should I pour more water over the perlite to bring the humidity back up?

Depends if the perlite surface has become drier or not. You'll probably need to feel the perlite surface daily with your hand to gauge moisture. Do you have pics of the cakes inside the FC? And don't worry so much about what the hygrometer says about the air inside, cakes will fruit in 99%RH and in 50%RH, they need to slowly and continually evaporate off moisture and the point of the damp perlite is to regulate and slow down the evaporation off the cakes. But in essence there is no specific humidity level you need to maintain, what you're maintaining is the evaporation off the substrates, you don't want the evaporation to occur too quickly/drastically and you don't want to halt the evaporation either by constantly spraying the substrates and drenching them, this is equally harmful as too dry cakes. Hope that helps.

Here are some pics of my set up. I noticed that some of the cakes are starting to pin. Any suggestions on whatever would be helpful. Thanks.

Stick your hand into the perlite. If it feels dry then rehydrate it. If it’s still wet it’s fine.

I feel them everyday and they are damp but definitely not as damp as when I first put it in, obviously. I just don't know what feels too dry.

1. like pasty said stick your hands in it. feels dry, wet, damp.

2. dry is when no perlite stick to you fingers. its same as taking perlite out of its bag.

3. damp is when you feel moisture on your fingers and no perlite sticking to fingers.

4. wet is when perlite stick to your fingers, when you hydrating perlite stick your fingers in and few amounts of perlite will get on your fingers. even when you put perlite in fruiting chamber and use your hands to fluff it out for air pockets it will stick on your fingers.

5. if you know its too dry you can mist water directly on perlite.

6. mist your cakes very gently its like making rain from a distance with very tiny particle of waters felling on cakes and when you are doing it right verm will never fell off cakes.

7. cut the foil bit more smaller to size of cakes.

8. check temperature. see if you are between 22c to 26c.

Misting the perlite surface daily buys you at least a guarantee that your subs will have a daily buffer zone for some hours before evaporation rates increase again as the perlite surface gradually gets drier throughout the day depending of course on the ambient RH in the grow area and Temps. At least the environment won't stay dry for too long periods at a time. Sometimes it's better to misted the substrates with a gentle list and sometimes it's better to remove the cakes spraythe he'll out of the perlite surface and place cakes back inside. Mushrooms grow in high humidity but they don't require nature to deposit small quantities of water on top of them just so they can survive or produce offspring. If that makes sense.


And trust me the perlite surface is alwaysvthe culprit as the top inch of perlite will become bone dry before the bottom inch barely has evaporated off anything. This may tell us something about the supposed 'wicking' hypothesis which claims that air travels inside the perlite layer from the bottom up and out through the perlite surface, humidifying along its journey bringing with it moisture from below. If this was the case then how can the top inch of perlite dry out before the bottom inch? Even tho the perlite surface is sprayed several times a day. That's in my book at least a pretty definitive indication that moisture isn't wicked from the bottom out the top but rather the Humidity in the SGFC is generated from the evaporating substrates and the perlite surface. That's why a SGFC can go bone dry in nano seconds when both perlite surface and cskes dry out simultaneously (they slow each other's evaporation rate down normally and regulate one another) but like I said this setup really requires a strict regiment of making sure the desirable functions/phenomena are occurring in a preferable manner. Hope that helps.


I'm actually writing a fairly detailed and carefully described 'essey' of sorts exactly about what we're talking about now,but I'm writing it in my journal which is not accessible to anyone until Im finished and perhaps have someone look over it once and then I'll publish it but I've made some very interesting and somewhat controversial observations when it comes to different kinds of growing methods and fruiting methods. For the time being just daily mist the perlite which is most likely the only humidity buffer for slowing down evaporation rates, that is your cakes only defense against the environment its in (having to intervene up to three times of more daily just to be able to maintain decent conditions should right away tell you how compatible that environment is to the natural environments cubes grow in.
