Yes they were, at least I believe they were. (fresh from the mail)

I'd say the myc is maybe grayish but it's hard to tell. Yes I inoculated to see spore water on side.

When I replaced the lids I was extremely carful and had a whole sterile setup so I'm not that worried but I'll keep knocking on wood.

and yes I will take photos today and have them posted by tonight.

Thank you for the help Anno I really appreciate it.

Hi there,

Ok I'm just going to tell exactly what I have done thus far and you tell me if I've done anything wrong or w/e please just tell me.

So I followed the PF-Tek almost exactly.  Prepared the substrate correctly, pressure cooked the jars for 45 -50 min. and waited about 6 - 7 hours to cool.  Followed this by sterilizing my work station etc... Now instead of using foil as a lid (I used Kerr Wide mouth 1/2 pint jars) and I punched 4 holes on each lid for inoculation.  For sterilizing I used a simple lighter and rubbing alcohol on the needle.....  After inoculation I put a piece of aluminum foil over the lids. I then placed the jars into my incubator. I have a little thermometer inside to read the air temp. and its around 80-85 F.... ok after waiting maybe 11 days I chose to take off the Jar lids and replaced them with a new piece of foil. (so now there are 2 layers of foil acting as a lid) I did this simply because I did some research and found that better air circulation can speed up myc growth. Although it has its cons too but thats a different topic.

Ok so now its been 4 days after I did the lid swap.  I have little to no growth of myc in any of my jars. I have 12. I'm just wondering if I did something wrong or perhaps I'm simply being impatient, either way I'd just like some help.

If I have been unclear about anything just name the specific and I'll post back with a more detailed answer.

Thanks and peace.

"It just does.
I don't study the specifics,just grow them  "

lol yea I know, but I love to learn. For their sake of course.

I guess I will have to be looking up how to pasteurize and make an efficient casing mixture.
Any tips would be helpful.

Thanks for the advice Baph, I'll try what you said.

Thank you, but I already have those sites.  I was more wondering what exactly makes the casing procedure produce more and larger crop. How is it really working and why? I'm a biology student so I just like knowing how.

-Also I'm a first timer with this PF-tek, do you think I should try one of these casing methods my first time or should I wait and try it on my second round?  My only real worry is contamination.  Don't casings add more chance for contamination?

Thanks,

and cool lyrics, I'm a fan myself.

Hi there,

I'm following the PF-tek and my babies are still trying to colonize their jars.

But anyways, I am curious to know what the pro's and con's are of casing.  I was originally planning on just using a normal fruiting chamber on wet perlite etc...  But now I see more peopling talking about casing.  I know how to case for the most part and if I find gray areas I'm sure I can look it up. I just want to know what casing or not casing does on the biological level. Thanks!
