Success rates with plastic lid + whole SFD?
    #26233366 - 10/06/19 11:21 AM (5 years, 3 months ago)

Currently I have the lids of my wide mouth quart grain jars set up like this. The entire synthetic filter disc is pressed between the ring and the lid.



When I'm doing agar to grain transfers, the ring/filter/lid tend to separate, and I think dealing with that causes unnecessary turbulence in the SAB.

I'm thinking about trying plastic lids + whole filter disc, as shown below (filter disc pressed between the plastic lid and the glass edge of the jar). The filter disc is exactly the same size as the plastic lid; fits perfectly inside it.



Have any of you fine people tried this? Any reason it won't work? Thanks : )

EDIT: Found SpitballJedi's tek about this, but as far as I can tell he never tried it enough to arrive at a verdict with regards to its effectiveness and if the contamination rates were any different than other lid setups.

You dont need a filter with the plastic one piece lids imo.

Most people prefer to silicone a quarter sized piece of sfds to the lid instead of using the entire thing.

Wait, are you guys saying that you colonize your spawn in air-tight jars? No air exchange at all?

For grain I'll use a filter with the two piece but the plastic lids  can be cracked for ge

I use the plastic lids with a little piece of sfd held on over the ge hole with rtv. I know you can use the lids cracked and unmodded but i don't like it. It's so easy and cheap to modify a shitload of lids in an afternoon and never have to worry about tightening and untightening unmodded lids again. But, to each their own.

And op, yes, many people have tried lids like those. It all works if you do it correctly.

Does this lid setup have a name so I can search it in the forums?
And what does 'doing it correctly' entail? Anything to know other than drill hole, put SFD in place, tighten lid?
Thanks : )

Hey did you ever try this out? I’m tired of rusty meta lids and I have a lot of sfds already, don’t really want to fuck with silicon and all that. Was thinking just drill a couple holes in plastic lids and put a full sfd pad under it?

As mentioned above, some have good experiences with just the plastic lid, no filter. This is also how I roll, cranked completely tight after inoculation. Average 2 week colonization with basic cultures.

I refuse to use them fucking two piece deals.

I basically jst drilled 1/4" holes in all my plastic lids and stuck a sfd sticker over it. Them stickers seem to work great. Jst ordered like 260 of them.

The plastic lids do loosen during pc cycle. That pisses me off. Seems like it allows water into a few jars here and there. Been trying to find a way to wrap the lids in aluminum foil so they dnt loosen, but they tricky.

I had always wrapped my upper jars in foil until a couple years ago. Always looking to simplify, I found it to be unnecessary.

Place in pc with lids loose, just tight enough to tap the threads, load cool into sab, inoculate, tighten, shake.

I started using these little sfd stickers on the plastic lids. I had my doubts but they've been working great. I hate working with silicon

Dem new kids should try poly filters. I promise they're not that hard to figure out and are as efficient as it gets. They are good for a good bunch of cycles before you have to change them, also they cheap.
IMO, glue of any kind doesn't belong on a lid, ever.

We old-school folks with our good 'ol poly filters, becoming scarce these days...

Same... I've only PCed them 2-3 times and they seem to be holding up so far. But I'm definitely not doing numbers like some of you fungalmancers. @Feasoghorm how may runs have you done with them?

Quick question... Are you guys putting these on top of the lids with the adhesive facing down towards the grain, or on the bottom, with the adhesive pointing up towards the open air?

i colonized spawn in airtight jars a few times. i would have to do a side by side comparison to know for sure but it seemed to work just as well. i finally put holes in my lids because i was tired of fighting to get them open after they vacuum sealed themselves in the pc. even if i left the lids loose they would get sucked down sometimes. also i was paranoid about contams getting sucked in when i unsealed them

I would attach them to the top of the lid with the glue facing in.

I use the below tek to attach quarter sized SFDs to lids:

Improved melted SFD/lid tek 2.0 (no more silicone)

This is how the Ball lids look when complete:
