SFD lids

Do SFDs fit perfectly in the wide mouth plastic lids? I'm getting the 90mm wide mouth discs, but do they work by just sticking under plastic lids? Or I have to get some adhesive and and to stick it under the lid?

I know you can do that, but the another option is under the plastic lid. It is my understanding that they fit underneath the plastic lids the best and stick by themselves right? I'm not doing any RTV to the top.

You can drill a 1/4 hole in your lid and rtv it in place then you can make like 10 lids with 1 SFD

I understand, but I will not be doing it that way. I'm going to use it as a whole with the platic lids. My understanding of it is that they just fit right under the plastic lids correct? I'm not doing any RTV.

yes the lids are also 90 mm, keep in mind it's humid inside your jars

SFDs cause humidity or something? What do you mean?

The heat generated by the mycelium causes it to be humid inside the jars, and this humidity could open potential vectors for contaminates straight through the filter.
I have seen many growers have success using plastic lids and no filter at all, they just crack the lid a turn or two and let it chill as is

SFD are the best way to go. What do you mean? That’s Rye Tek correct?

So are you going to drill a hole or just put SFd inside a lid and screw it shut?

Why no silicone??
I was gonna just switch out my lid sized tyvek circles for the whole disks too, but when I got them it seemed pretty wasteful and they’re so thick. Plus it’s super helpful having one piece lids for SAB stuff.

That's one I'm trying to do, achieve as one piece easier lid and shake. I ordered SFD's, should be coming. I saw SpitballJedi's lid teks, I'm just going to stick them underneath. They just stick up under there is my way to achieve a one lid. I don't think I need adhesive or anything...? I just don't want to take time cutting all that whenever I just want straight and simple. He says just drill 1/4" hole in center of plastic lid and stick SFD underneath.

Seems wasteful if your doing 24+ jars.

Eventhough you don't want to still going to recommend you cut small circles and RTV them to the top of the lids. You need way less material and it will function a lot better. They will stay clean and be usable over and over.

Sfds are expensive. You could buy 5 and make enough lids for 20 plus jars. Or you can buy 24 and spend $. Some people have said they had issues with sfds coming off with rtv used to attach them. Ive literally run them hundreds of times for 10 plus years and had maybe two come off in that time.

I'm going to follow the lid Tek and use them as a whole piece under a plastic lid (with a hole drilled) in the middle. What side is which on an SFD? Should the granule filter material side go up against the lid underneath it so that's what you see through the hole? Or should the smooth side go up against underneath the lid?

Just make sure you don't get those cellulose filter. They are more like paper than poly.

Yea the cellulose filters suck.
I like to use whole sfds. Those plastic kids just don't seal. Whole sfd gives them a airtight seal. Plus the fucking lids warp even when left loose and I end up throwthimg them away it would be more wasteful of I was cutting and gluing sfds. Now that I switched to regular mouth I don't really have a warping problem, so I may start gluing bit for years I was using widemouth and damn near every other kid would warp in the PC and I don't sick around in a SAB with warped lids. Idk how shroomery can be so against whole sfds. I've had people damn near steaming out the ears trying to argue with me that I need to cut my sfds, when I don't wanna. They are my sfds if I wanna leave them whole I will I don't see how this upsets people so much.

Sounds like you have cellulose filters, I have some but never used them because there so thick. FungiP sells SFVs for a decent price. Iv run full SFVs under plastic lids my last couple of grows and I probably won’t go back. Edit: yep their my disk and it’s my money so if I want to spend $60 on 100 disks then what’s the problem
