I'm so glad to hear it!

I misremembered and for some reason thought you had to drop a lot of the plate on each jar. Guess I'll put 1-2 wedges on each one.

I'll do some grain jars and some LC cuz they're fast to prepare.
Have 2 1-month old WBS jars that look fine which I think I can use. And 3 more that I'm straining and will be ready tomorrow.

My suggestions would be to only use 1 wedge per jar because it lowers the risk of contamination, at least in a SAB. I use 60mm plates and almost always divide that between 4 jars, but I have done 6 and it didn't take more then a couple of days extra in terms of colonization time on my jars

I use the standard "thick" SFDs exclusively. They work great.

Yeah I know you do, you bad boy

Joking aside, yeah I saw your video when I first started out, but couldn't source the thick SFD's then. Now that I have them I was wondering if they allow enough GE so that I could tighten the lids as soon as I pull the jars from the PC or if I should wait until the jars are cooled, just looking for another way to keep contamination out of my jars

I've read about people even have the lids tight during PC, but that sounds sketchy How are you legends doing it?

I only bother putting loose lids in the pc with unmodded lids

Then again you're a hardcore gangster, and I'm a scared virgin, when we speak about mushroom cultivation I mean

Are you using the leak proof plastic lids and thick SFD's?

Stipe-n Cap said:

Oh, I see. I misunderstood. As trypt pointed out, you can run loose lids unmodified. The threads function as a type of barrier to contamination, much like a swan neck flask does.

what I am wondering though is, with RTV'd "thick" SFD modded leak proof plastic lids, can I tighten the lids before the jar is cooled to room temp or would that result in vacuum and deformed lids?

I was also wondering if foil on the lids helps keep the SFD's dry(during PC cycle) and or helps with contamination since the foil goes further down the jar then the threads does(while cooling).

Most likely I'm overthinking this, but I'm still wondering.

I run my sfd llids without tinfoil and they work fine.

I'm using cheap Amazon lids and I find that they're loose if I take them out hot but if I tighten them they're difficult to take off when cool. I believe the plastic is softening/expanding just a bit when hot and shrinks as it cools. If I take them out hot to use the PC again I only tighten them with my fingers until I get the slightest amount of resistance any more than thatand they need a lot of force to loosen. If I let them cool in the PC they don't have to be tightened.

---

Thanks for the input and insight Puff, appreciate it And yes the plastic will expand and shrink with temperature change. I'm wondering though, if the cheap lids might do it faster because the plastic is thinner? And are the lids you use leak proof? This will be the first time I let my jars cool inside the PC so thanks for sharing this, I'll check mine tomorrow.

i try not to mess with anything other than agar until its at the same temp i put it in at

Got it, see the reason I am asking is because I thought it was okay to finger tighten the lids with sticker SFD's before a PC cycle, turns out though that 2 of them warped when they where cooling. Now that I have change to RTV'd thick SFD's I'm just looking for best practice with new lids, thanks for helping me get this, sorry for needing it spoon by spoon

Keep them finger tight at all times, don't crank them down. They won't warp in the pc because they have a filtered hole which maintains an equilibrium.

The foil won't keep anything dry, it acts as a touch barrier to maintain sterility while handling. Steam will penetrate the foil and the SFD to enter your jars and displace any dry pockets, this is the reason we vent.

The video is a demonstration of the above.

Foil isn't strictly necessary but you've already gone through the trouble to produce sterility, the foil allows you to man handle the lids/jars while maintaining sterility.

---

As I mentioned above, 2 of my lids warped while cooling down when I used the sticker SFD's and I believe MycCycle experienced them blowing off during a PC run if he tightened the lids before the run

That was one of my concerns when I asked, I want to make sure that it is okay to finger tighten the lids or if that would create to much pressure inside the jar in a way that could compromise my filters or the RTV. But if you do it all the time I guess that is not a problem with thick SFD's.

Nice, then foil it is, that was my initial thought and what I ended up doing today, but appreciate you confirming it so I don't go around "cleaning shit that doesn't need to be cleaned"

I've seen all your videos, but I'll have a look again, just need to get out of my son's room without waking him up and have to do the sleep rutine all over again

I wanna know how to move in my SAB to reduce contamination. Is there a tek or instructions on how to do this on the org, I can't find one anywhere.

So I am looking to upgrade some from doing 6qt shoeboxes. I have a 16 qt bin I’d like to use. Is there a good rule of thumb for spawn per qt bin?

With the bigger bin do I need to worry about FAE at all? I was previously just using the method of leaving the lid on but not sealed.

Thanks for any help.

I do my 12qt ones with 2qts of spawn + an appropriate ratio of coir for the cleanliness of the culture.

Anywhere from 1:1.5 up to 1:3 if I'm feeling froggy.
