Idea for SFD- Would this work?

So I'm about to start some sclerotia rye jars. As this is my first grain project, I had to choose an option for filtration other than a verm barrier, and I was reading about SFDs. I read some false information than you can inject through them and they self heal but now that I've physically seen one of them and felt the material, I now see what I'm dealing with. I don't want to order anything else online or make any more trips to walmart (live in the sticks..) So I was thinking I could put the whole disc in the metal lid (Lid on bottom, then SFD, then ring, have a hole drilled through the lid and SFD for inoculation (micropore tape over hole before PC and another layer after innoc) and a bigger hole just drilled in the lid for air exchange. I also don't have any silicone but I figured if I did it this way I wouldn't need any, however I could pick some up if I had to. Any comments or constructive criticism? Would like to get this sorted out before I do anything, Thanks

Actually, come to think of it I guess I wouldn't have to drill through the SFD for inoculation, I could just poke through the tape and disc with the needle and then re-cover it with micropore tape as I planned.

You dont want to puncture the sfd. I have lid with two 3/8th in holes, under the sfd, under the ring. You should be using agar but if you insist on using spores just open the lid to inoculate.
Tin foil on top of the jars for pc cycle.

I've never had to open the lid for inoculation, so you think it would be riskier to puncture the disc and patch with micropore tape than it would be to crack the lid open for a second?

Puncturing the sfd is risky/a bad idea. A large majority of growers successfully open the lid and inoculate with agar wedge. Again you should look into agar its a great way to make contam a rarity and its just nice knowing your spawn is clean.

Get some RTV silicone and do this. Cut small rounds out of your lid sized disks and one will cover many jars. I live in the sticks and hate driving to town as well, but do it right the first time so you don't have to waste time and trips.

Yup, here's a cheap easy way to get into agar work: https://www.shroomery.org/forums/showflat.php/Number/19208976/page/1

I don't know why I thought this would be too much of a hassle, I'll just go ahead and pick some RTV silicone up from a local auto shop on my way to work. So let me get this correct, cut out circles from my disc and silicone them ontop of the air exchange holes,(I see the guide shows it underneath the lid, but RR says otherwise..?) and have the inoculation hole with no filter or tape, just a blob of silicone that self heals after the needle passes through? Do I need to make sure the needle is hot enough for the silicone to melt and heal back or does it not matter?

I'll probably still use foil, I have plenty and it keeps everything dry

The sfd keeps everything important dry, i promise. I never use foil. be kind to the earth and save the foil if you already are using the sfd..

Water rains down from the ceiling of the pc dyring the cycle, you can re use the foil to be environmentally conscious.

It makes no difference with sfd. Why use something unnecessary that will just get thrown away? Seems irresponsible imo

Well thank you everybody I'll keep all of your tips in mind along with the research I have done, however I'm still a bit confused, SFD circles ontop of or under the lid? Or is that just preference. And also does the needle still need to be hot during inoculation for the silicone to properly "self-heal" . Thank you

Yes the silicone is self healing, NO DO NOT pu the needle in it hot. Squirt a drop of two out of the needle to cool it first.

I just crack the lid, it's not hard.

 once you start using agar SHIPS and stuff kinda become obsolete anyway.
and if doing stones dont you want agar? not only to clone a invitro pin/stone and id imagine opening a 6month old bacterial jar would smell something fierce.

Im not doing agar because of the same reason im doing sclerotia.. dont have much space and i want to keep it low key anyways. I went ahead and picked up some of that high temp rv sillicone today.
