SGFC'ers I need your help! Gimmy your conditions!
    #17824958 - 02/18/13 02:07 PM (11 years, 13 days ago)

The SGFC is a pretty slick setup, making a semi-self contained micro climate with minimal if any needed external care.

I really want to see what makes them work from a engineering thermodynamics/fluids perspective. I mainly want to do this for shits and grins.
Who knows, maybe it could be used to help some people out.


I looked around and couldn't find any calculations of this sort, I think RR said he tried once, but lead it to some nasty headaches :eek:

If you're running a SGFC right now, if you could tell me:

  • Humidity Measurements-
     
  • The RH of the room your FC is in.
     
  • Current RH of your SGFC
     
  • Outside RH (check online weather site)

  • Temperature Measurements-
     
  • Temp in your SGFC (taken from the middle of the chamber if possible)
     
  • Perlite layer Temp (Poke a thermometer in about the middle of your perlite)
     
  • Temperature in the room where your SGFC is
     
  • Outside Dew point temp (Again from online weather site)

  • Barametric pressure (Again from online weather site)

If possible take SGFC Temp/RH readings prior to misting/FEA if you do this.

Also I'll need:
  • SGFC Size (qrts)
  • Number of holes
  • Size of Holes

I am going to assume you are following RR's tek, meaning you have  1/4" holes @ 2" apart, on all sides. There is 4" of perlite on the bottom. The chamber is slightly elevated and in a room with free air circulation.


Due to the large degree of variables that vary place to place the more data I can get from independent sources the more accurate the calculations will be.

The more SGFC'ers with data to share the better :laugh:

Thanks!

I dont use a SGFC but I am interested to see where this goes.

Not currently running one, but I can give you all the information I can remember.

Room RH - 32-37%
SGFC RH - 99%
Outside RH - 80%

Room Temp - 70-74 F
SGFC Temp - 70-74 F
Perlite Temp - Didn't monitor, so IDK, but sure it's 70-74 F
Dew Point - 41 F
Barametric Pressure - 29.42 inches

Thank you! I edited the post since you posted. What size was your container, how many holes, and size of holes. (Assuming you followed RR's tek)

:shrug2: on how many holes. I'm not counting them.
It's a 116L (123 quarts) Tote.
Size of holes is 1/4" per the tek.

You may want to use the proper abbreviation in your title.
SGFC, not SCFC :smirk:

I will post as soon as I get home. I had made a mistake and forgot the holes on the bottom (first time). After cleaning up perlite soup, I am ROCKIN. Tub is getting stabilized. Will report soon!

Not running one atm, but I can give you all the info I can.

Room RH  45-55%
SGFC RH  95+%
Outside RH  60-65%
Room Temp  68-74 F
SGFC Temp  72-80 F
Perlite Temp  dont know assuming it would be a few *F colder than the scfc temp
Dew Point  55-60 F
Barametric Pressure 29-30 inches
this was a 66qt SGFC
24.5"x17.75"x13.375"
too many holes to count but theyre 1/4" spaced 2" apart on all 6 sides

hope this helps

Thank you so much! It may be a awhile before I crank out the calculations, but it will happen. I'd really like to get a good data spread first though.

In the name of science, I will construct a SGFC for this.  It's been awhile since I used one, but I -loved- mine.


Data forthcoming in future bump.

i used my face as a hygrometer so i dunno specifics, but i love the idea behind this post. the sgfc was a huge development in indoor mycology but everyone always insisted it gives the same result no matter the ambient environment, but this isn't exactly true of more extreme environments.
i have nothing else to add, just wanted to feel like i am a part of something, so i joined this thread.
