tyvek for fruiting chambers?
    #3617548 - 01/12/05 01:14 PM (12 years, 1 month ago)

hi.

i searched this site and even mycotopia.net and i didnt found anybody mentioning the idea of using tyvek fof fruiting chambers.

let say, you drill a large hole near to the bottom and cover it with tyvek.
co2 will start to flow out, as its heavier than o2, and contams will be kept outside, and humidity would be kept inside.sounds nice, but wouldnt the humidity "wet" tyvek and close the way for air exchange?

its just an idea of mine tough...

all the best

why filter a bottom drain hole? FWIW, i leave mine wide open with no problems ever.

i would expect water to pool on the tyvek as opposed to dripping out to a easily accessible basin. pooling water is always bad.

altho, to answer your question, IME wet tyvek allows air exchange just as well as dry.

i recall SixTango using some sort of gardening mesh to completely/mostly replace the bottom of bins for bulk work (thread is prolly ~2yrs old by now)

edit: oh, yeah, i was thinking it might be pertinent to note that i have filtered air being pushed into my bins so the open bottom drain hole actually has air flowing out it thereby preventing contams from being able to "float" in.

i thought that tyvek was used for gas exchange not air exchange thats what i read most offten

6T used a commercial grade spun-bonded polyester landscape fabric - available at Lowes & Home/Depot (3X50 ft roll for around $12).

Material is very much like TYVEK, ??EXCEPT much more porous. He drilled holes in the bottom of his bulk containers, PC?ed the fabric & lined the bottom of the containers with it.

Object was to allow some minor drainage. He also covered his bulk casings with the same, as it will keep out gnats, but let light & air through. After casings began to develop large PINS, he removed it.

6T also discovered that one could lay a single PC?ed layer of the same material DIRECTLY on the top of a colonizing substrate, then when fully colonized??add the casing layer directly over the top of that material. Doing so allowed for better moisture distribution through the casing layer to the substrate.

Having that thin porous polyester layer between the casing layer & substrate also prevented pulling up substrate with the butt end of mushrooms - when harvesting with the "twist & pull" method. It also increased the effectiveness of patching the casing layer, thus increasing "flushes" & minimizing contaminate entyways.

Material looks like this (against a white background).

anyway thanks for all the answares...i hope i will figure it out somehow sooner or later...

drilling holes into the casing tray and cover the inside with tyveak also seems to be an interesting idea to me...

happy growin'

thats my plan:) co2 is heavier than o2 so they eill switc places in order to make co2 fall down.

-Maybe a stupid question, but will the colonized substrate travel through that material and into the casing?

This worked well. Just regular envelope grade tyvek.

I'm doing something like that except I put the tyvek on the two opposite sides with an air bubble inside a tyvek container to supply air and humidity. Still waiting on my jars to colonize so haven't tried it yet. I think I would work though.

cool design ddaedalus!:)

the only thing i would do differently. the lower side of the tyvek should be at the top of the casing soil, or maybee a bit lower because co2 can be trapped on the casing soil..or maybe i am just stoopid:) anyway great box.

dod u close the top hermeticaly, and u just had the tyvek for airflow? how pften did u open it?

Yeah ideally the vents would be flush with the casing, but I don't think that it's a huge deal. I think for this setup there was a great deal of heat being given off, which created a convection of sorts in the chamber and mixed up the gasses. The top was sealed and only opened to provide accesss to the substrate. There seemed to be plenty of air exchange, but the vents could have been a little larger IMO.

yeah heatflow is another factor:) i didnt thimk of that.

it would be cool to make wholes on your container below casing level and cover it with tyvek, that way air would fall out trough your substrate...or maybee heatflow would be more greater than gravity, maybe the air would flow into the substrate from bellow? wheter each version, it would be a great o2 support for the mycelium, but i am still not sure if it would be safe from contams and driing out.

vents are noisy:)

all the best

You could always do a double tub. Tyvek would eventually get lots of condensation built up inside of it and contam. (hooray for contams).
Double tubs typically have holes in them with polyfil....one of each side....4 on the top to allow air to come in, 4 almost on the bottom towards the top most layer(casing layer) to allow co2 to escape..

Plus when you go to clean it, you can just pull out the polyfil and spray the chamber down and put more in...tyvek would be a bit more of a challenge....especially for those of you who like to "silocone"(cant spell for jackshit) it on there...

Viola...problem solved..

double tub is basically one tub on top of another...do a search Double tub...I guarantee that u'll find something

hi

hmmm.interesting. i did search the net for "double tub" and i did found a lots of things, but i still cant clearly see what is this "double tub"

i imagine its some kind of filter used for washing machines and stuff?

i will keep trying, for only i did 5 minutes for the case yet:) thanks for the advice

k i got it:)

that just what i was thinking about to do...except i would do the same thing with tyvek..so u say polifyl would be a better idea?

i would tape on the tyvek from outside, so it would be easi th replace them,
lets say after every flush..

its amazing, the more i think i know about mushroom growing, the more i feel i dont no bullshit:)

have a nice day:)

How about using fish tank filters instead? (which have the same material as polyfil filters).
