pinning in and around vermiculite (PF Tek)
    #5898767 - 07/25/06 04:23 PM (17 years, 6 months ago)

Hello all,

What would cause pinning in and around the vermiculite area of 1/2 pint jars (using a variety of substrates)? Incubation took 3 to 4 weeks and was done at 84F app. It's been pretty hot for pinning (around the incubation temp lately) so jars were placed in fridge (after 10 days app.) and that seemed to do the trick a few days after, but the pins are almost exclusively in the vermiculite area. Could it be the pinning temp? I think there is enough moisture but not really sure. Mixture was 50% Verm, 25% subs, 25% water (on average, rye substrate had to have more Verm as it was too "gluey". There is no blueing or shrinking of the cakes.

Thanks,
Earthmansurfer

what are you fruiting in? invitro? inside of the jar? if so, the shrooms will most likely fruit through the verm barrier... otherwise i have no idea what you're talking about

Vermiculite in a PF style cake kinda acts like a caseing... Does that help?

ok from what i understand from the situation is this, you birthed the caked and left that protective verm barrier in place. Now after you birthed pins are only coming out from the verm.

If I am correct then i would have to assume that that your humidity is to
low and and the verm is acting as a casing (therefore providing a good climate
under the verm for pinning)
keep your humidity at 99% and utilize 100% of the surface area of the cake

Moisture is high in wet verm.

Sorry I wasn't clear enough. I left the cakes in the jars for pinning and exposed them to indirect light (with high humidity (In my poor mans pod but without the bubbler going, though water at the bottom)). Lids were on but loose. After 9 days or so and no pinning, I put 1/2 of them in the fridge (no water added this time) and sure enough they started to pin a day after removal BUT only from the verm area (sides and top). I took them out of the jars and set them in the pod, some top down due to the pinning problem. They are growing nicely but of course not so fully. I did not try to pin them by taking them out of the jars. With the other (1/2) jars (not yet pinned) I cold shocked them with water, drained, took the lids off and set the jars in the pod (with bubbler going and other cakes). Very little water was added/absorbed by the way, so I don't think they were too dry.

Thanks for your time all,
Earthmansurfer

Your suppose to take them out of the jars when birthing them to the fruiting chamber bro! They also need the drop in CO2 levels. Not sure where you heard the leave them in there jars but p-lease link me so I can dispose of such trash! LOL :wink:

hyphae,

  I took them out of the jars for birthing but left them in for pinning. With the second batch (to raise humidity levels and drop the CO2) I put them in the pod but with the lids to the jars off. I'm just trying to get them to pin. they are growing, just mutch less than I thought. I can't complain, no contams out of 16 jars!
  Just so I understand this correctly...
1. Incubate till fully grown with Mycelium (2 to 3 weeks)
2. Initiate pinning by exposing to indirect light (1 week, maybe two)
3. After pinning birth them (out of jars  :tongue: )
    So, I'm just wondering what could cause the pinning to occur by the vermiculate layer (though after birthing those a few started to pin elsewhere). Any ideas on this?

Thanks again,
Earthmansurfer

They are pinning out of the verm layer because the verm layer is a better surface to promote pinning, It acts as a casing.

Thanks, but how do I stop that next time? What did I do wrong.
I'm trying to perfect this first try...  :grin:

> I took them out of the jars for birthing but left them in for pinning.

Birthing IS taking them out of the jars. You should birth them after 100% colonization or 1-3 days later. Don't let them pin in the jars.

Scrape away the verm layer when you birth them, or you can leave it on just be sure to wet it by dunking or misting if you do.

Read my pinning strategy it basically works for cakes too. And keep that RH as high as you can (95-98%) throughout your grow. Definitely go back and readup as you do have some confusion on pinning going on. GL

You don't want to stop it just Dunk and Roll so that the verm is spread evenly across the entire cake. That way you will get an more evenly distributed pinset... (in theory) :wink:
