Greetings everyone. I'm new to mushroom cultivation and am in the mists of my first try. I'm using PF TEK with the PF classic race. My jars are not quite colonized completely yet, but I think they are pinning all ready. Is this normal? Just a little nervous, cause I don't want to birth the cakes early. Everything I've been reading says to wait about a week after colonization is complete.

A harvesting question. Once I birth the cakes, are the mushrooms harvested once they become ready (one at a time) or is a whole cake harvested at one time?

As I've said I'm new to mushroom cultivation and just discovered this board a couple of days ago. Looks like it will be a good source of information and I have lots of questions. I'll save some for later to keep my first post from being filled with questions.

Thanks in advance and I look forward to getting to know all of you and tapping into your knowledge.

I used Kerr wide mouth half pint jars. After inoculation I let them sit in the corner of the room were they are receiving indirect light.

I inoculated the jars in four locations (except one jar, I missed a hole, oops) on September 5th. I'm doing cubies, got spores from PF and am using the PF race. The only part that really isn't colonized is the bottom of the jar, and no it doesn't look any different. The whole jar will probably be colonized when I get home tonight.

I'm pretty sure its pinning, as it looks like some of the pictures I saw. Small shrooms, brown heads.

A little pinning in the jar before 100% colonization is O.K.

Maybee you exposed your jars to light a bit early.... next try introduce light a little bit later.

Leave the cakes in the jar until 100% colonization is achieved though... the pins will be O.K.

As far as harvesting goes.. you pick stuff when it is ready... it will not all be at the same time though.

Thanks for the responses.

Open. Surprised no one said it. Flip your jars upside down to drain out the Co2 and let the bottoms colonize. In the future, put 1 tablespoon of verm. in the bottom of your jars before you add the substrate.

You aren't supposed to give them light until after you birth them by the way :)


By Open (Open) on Thursday, September 27, 2001 - 09:46 pm:

Saney. I've got the jars sitting with the bottom down and the lids on loose. Shouldn't the CO2 be able to escape? Should I place them with the lids down?

By Saney (Saney) on Friday, September 28, 2001 - 07:00 pm:

No it can't go anywhere :) Co2 is heavier then air. Flip your jars, lid down and the cake should fall down ontop the lid causing a vacuum reaction and suck new air into the jar.. the Co2 will eventually drain out through the holes in the bottom and you'll be left with a fresh new jar of air :) You only want to do this after your jar is 80% or more colonized, sucking new air in can mean sucking in a contam, at 80% it should be able to fight it off and you shoudn't have a problem.. Spray some lysol around and let it sit for a little while, then flip 'em. If you don't have lysol, a 10% bleach %90 water mix spritzed in the air will work too. Peace.

Okie I Have a Question, but first the materials used.
-Pf Brown Rice/Vermiculite Substract
-Pressure Cooker For 30 Minutes In 1/2 Pint Ball Non Wide Mouth Jars with tin foiled lid's for sterilization of the substract
-Inoculated Pf
-My Question is as follows I have a cake which is 1 month into colonization, The cake is healthy but it has started pinning prematurely as in the cake is not fully colonized. Only the very bottom of the jar<very bottom> is not colonized the pinning all ready has Red Heads and some blueish color. Any suggestion's.
Any Help is Appreciated
???Also One other question on sterilizing
We Pressure cooked with a Large Pressure Cooker about 16 jars I noticed some heavy settleing after sterilization A friend told me to leave the jars in the pot untill all the steam had been released after sterlization time Does this affect the substract.???

you should leave the jars in the pressure cooker until it cools... if you want you could probably just birth it and clean off the uncolonized parts so it doesn't contam and give it a dunk ........ here is some stuff about slow or stuck jars

Non-wide mouth jars, eh? That might present a problem upon birth. Start reviewing Flatcakes just in case you have to break the cake to get it out.
