sfd lids?

I finally have some spare cash ( of course after i bought ez felt lol) and plan on getting some sfd's. I just have a couple questions about them that i couldnt find the answer to. 1) how can i inoculate my jars if i keep the discs whole in the lid instead of connectign them with rtv? Although i have the rtv holes for syringes, wont the needle still have to go through the disc and in turn make a hole for contams to get in? 2) my last question is kind of dependent on the first lol if i have to cut them up and attach with rtv, how would i clean the lids without getting the sfds really wet? and ive looked at a bunch of lid teks im just curious what your guys' preferred lid tek is?

Don't try to stab your needle through an unmodified SFD.
I wash my lids with attached SFDs and don't have any issue if the filter gets a lil wet. The SFDs don't seems to suck up water that easily for the most part. If any of my lid SFDs get wetter than I find acceptable I just throw the cleaned lids into my dehydrator for 30 mins on max heat. Then my jars get filled & PCd.

with the unmodified discs, i didnt think i should stab them but then how would i go about inoculating them with a spore syringe? thats where im confused lol and i didnt even think of putting them in the dehydrator thats a genius idea

you make a self healing injection port. I have a tek for what youre trying to do in the link in my sig. Just switch out the polyfil step with your SFD and your gold.

If you want to keep the discs whole, you need to inoculate your jars inside a still-air box or in front of a flow hood. That's good sterile practice anyway. Wipe the lid down, remove it, inject the spores, and re-seal the lid. When you progress to agar work you'll still be able to use that technique.
If you don't want to open the jars, you'll have to cut the discs at least a little. You could drill a small hole in the SFD and fill it with RTV to make an injection port in the disc. You'd have to line it up with a hole in the lid.
Perhaps a better option is to cut the discs into small pieces that you glue over the GE holes in your lids.

i understand that way tbag, thanks though! i appreciate it and will have to read through most of that stuff and see if i can upgrade my system before my next grow i guess ill do it that way and just trim some sfds to just bigger than the hole. i was wondering how you would do syringes with an unmodified sfd that was the size of a wide mouth jar. i cant see a way around having to poke a hole in the sfd... could it possibly be that the whole sfd's are only used for g2g instead of syringe inoculation?

Ahhhh this is where i misunderstood. I thought he was trying to make SFD lids not use the SFD as a lid. Dont mind me, I have nothing to offer in this field. I always thought that the grain would get too dry. Post results when you get it figured out?

No, you're right, tbagtag -- you can't use an SFD instead of a lid because it will dry out your grains. You put the SFD on top of or underneath the metal lid, with small holes drilled in the metal lid for gas exchange. RR describes this in his videos.

Water won't harm SFDs. They'll just be wet. The heat of a dehydrator shouldn't harm them either; after all, it's not as hot as a pressure cooker.
I've heard it said that wet SFDs can wick contaminants through. My personal experience, though, is that I've had SFDs come out of the pressure cooker wet a few times (from condensation dripping down onto them) and those jars never contaminated. But that's just a few times.
