I am about to recieve my first syringes(4) in the mail, but I don't plan on using them all right away.
Can someone please tell me, do I need to refrigerate them?? Keep them warm??? Or just toss 'em in a cabinet somewhere???
Thanks in advance!!!

Pop em in the fridge.

you can also store them anywhere it doesn't get too hot, a dresser drawer is ok.

i'll bring this up again, since there is controversary.

quo what's the oldest PF syringe that you've had germinate?

Nan says a year tops. This is not my experience, necessarily, but I've never heard your take.

just wondering what you think since you've previously said that they'll last longer. any numbers? syringes good for 3+ years?!

oh, and another question, while I have your attention. what are the oldest gelcaps you've tried? 5+ yrs. old? would this work?
thanks, quo.

take care of you-self. beat that flu bug!

i've got some syringes that are a couple years old and still good [i always save the last cc for later liquid cultures], they've been stored in refridgeration.
as for gel-caps, dunno, i eat them too fast to have any left from 5 years ago.

You know there is genetic variation in the spores. Some spores seem "hotter" than others... Quicker germination, more "robust" germination. I would not doubt that a potent spore syringe could last longer. On the other hand I have seen syringes stored right alongside that germinated weakly, took longer to germinate... And whose potency seem to decrease rapidly with time.

Do I have any hard science? No. Just an educated guestimate. I have had syringes that were 18 months old that eventually did germinate at 20% of the inoculation points, took forever to colonize, and never did fruit. The syringe was fine 6 months earlier, if a bit slow... But I was never really impressed with the potency of the spores in the syringe to start with...

Your mileage may vary.

i think you've got it right, nan.
germination rates decrease over time,
but this can be offset by using more.

By Underground_Shaman (Shaman) on Tuesday, November 20, 2001 - 02:47 pm: The Nook

yup, genetics is the key!

me neither quote!!!

good advice all around.

What's the longest you've ever had a viable spore syringe? The reason I ask is that a FOF made many syringes at one time and has been using them as time goes by. They are now about 9 months old. They have been kept in the fridge in the veggie tray. They were still good about 2 months ago. I noticed last night that when they are shook up you could see the spores but also could see a few white flecks floating around in there also. What could that be? Are they still good?

By Spun Yun Gi (Spunion_Elf) on Monday, January 21, 2002 - 07:51 am: The Nook

From what I've read, still good (for much longer than that), white flecks are the beginnings of mycelial colonies.

i'm sure they'll work fine. i used a vendor syringe that was around six months old once and it worked great, it had some germination going on in it as well and was stored in a drawer at room temp. personal syringes might remain viable even longer than vendor syringes b/c of the greater spore load.

Okay everyone,

I hope this isnt too redundant given my long absence from the community, but, here is my question...

What is the longest anyone has kept and used successfully spore syringes?

I have had about 6 syringes in the fridge for about 10 months. What has everyones experiences shown as far as shelf life?

Appreciate any advice and background,

I've never kept mine for a long time, so I don't have any personal experience, but as long as yours did not freeze, they should still be good.

By Shroomscience (Shroomscience) on Sunday, February 03, 2002 - 03:38 am: The Nook

Thanks Brettie,

I assumed, given the life cycle in nature, they would be viable still, but, just checking with others experience. Thanks for your input. Hopefully I will get someone who has pushed the time envelope a bit.

Have a good night,

Shroomscience, I stored/forgot 2 PF syringes (in original box) in my safe for just over 10 months and they did as well any have fresh from the mailbox.

By Shroomscience (Shroomscience) on Monday, February 04, 2002 - 01:13 pm: The Nook

Thats what I was hoping. Thanks for the post. I figured as much, but nothing would be more depressing than innoculating a bunch of jars only to find out weeks down the road that they were compromised by time.

I will be sure to post a followup to this thread and state the outcome etc, ...


By sleestak (Sleestak) on Monday, February 04, 2002 - 05:03 pm: The Nook

I just used 5 syringes that had been in the fridge for almost a year and they are colonizing quite nicely right now. I had actuall asked the same question about a month ago Spores are tough!
