Grain Juice on SFDs
#23482364 - 07/27/16 01:24 PM (7 years, 6 months ago) |

I bought plastic lids before I read this and now am hesitant to use them, but Ive read the RR doesnt like using plastic lids, because when you shake the jars, some of the grain juice will settle onto the SFDs and it has caused him a lot of contams. He recommends Metal Lids wit the SFD over the lid and under the band I would love to try out my plastic lids, but I am more worried of opening a vector for contamination with grain juice sitting on my SFD. For those members that use Plastic Lids, have you ever had issues when you shake your jars, grain juice on the SFDs and contams?
please chime in

i made mine this way.
havent used for grain, yet, but if the worry is the grains getting on the SFD, because it's on the bottom, then this way should help you out. it just RTV's an SFD cut-out, the size of a quarter, to the top of the lid.

I use plastic lids and haven't encountered this as an issue.

As long as you don't make the holes larger than the grains themselves (just make more of them for proper GE), your grain isn't too wet (which is a vector for contam anyway) and you keep the SFDs on the OUTSIDE of the lid, it really should be fine. At least IME, plastic or no plastic.

Why would more "grain juice" stick to the SFD when they're glued on plastic lids over metal lids?

having a large filter exposed to the grain is a bad idea.
If your grain comes out of the PC dry you can get away with it but you're merely getting away with it, it's not ideal.
If you use LC or LI or just make your grain up with measured quantities of grain/water no soak/simmer when you shake the jar grain can stick to the filter and trich will grow straight through it. Happened to me many times with tyvek. Grain looks perfect in the jar but you pop the lid and see a kernel stuck to it covered in green dusting your spawn below it with spores 
For lids I use stainless foil. Unlike jar lids it doesn't rust and is completely flat against the filter, no dome shape to indicate if a jar is pulling a vacuum which makes a cavity between the lid and the filter.

I believe the answer to that is science. Lol hell if I know. Static maybe? Can't say I've had this problem, my grain is never wet enough to produce "Grain juice" and if it ever were, it'd be because of sloppy grain prep.

I guess my point was, regardless of the lid used, if grain juice is getting on the SFD either your grain is too wet, or you'reQuote:

Maybe not me, but the answer I gave may have merit. Plastics can become inherently negatively charged, while steel by nature, does not carry static charge and is neutral.

Plastic in the situation of a grain jar lid really.. shouldn't be becoming charged at all.

please tell me more about how grain juice is affected by electric charge from a plastic lid and how said charge makes it stick better to the SFD next to it 
the gif is just a nicer way of saying man you really dunno what you're talking about, stop guessing.

Unless of course you do something crazy. Like shake the jar. But maybe I'm wrong - Any other theorie
And spacechildo, understanding how a positively charged organic material sticks to a negatively charged medium isn't a hard concept to understand. Unless you just want to be a dick and give me a hard time for no reason, which isn't necessary. The OP asked for "chimes" so if you want to be an ass with your thinly veiled gifs, knock yourself out.

I dont wanna be a dick and I'm not giving you a hard time, I'm trying to tell you nicely STOP guessing, this is a forum for mush cult knowledge not all newbs come throw out your wild theories and call them "advice" or "just trying to help". stick to reading and asking questions and keep your wild ass guesses to yourself

It's an educated guess, and honestly has nothing to do with mushroom cult and more honestly to do with physics. As an engineering major, they teach you things about thermodynamics and electromagnetism, and how it can effect your career path. So it isn't entirely talking out my ass. But since you'd like to assume everybody with a post count under 100 is a noob, and be an ass about it at that, you've earned yourself an ignore. Heres to not dealing with your shit anymore
Cheers.

I'm sure you're a great engineer but it wont help you much here. We dont engineer living things. post count had nothing to do with this, it was all based on you talking BS, easy to see you havent grown yet.
And putting me on ignore wont stop me from correcting your bad advice, it will only stop you from seeing me do it good luck in your echo-chamber, hope its warm and cosy!
