we did the pf tek. watched the video. followed directions to a T... sterilized the shit out of the room. steam sterilized the jars for 90mins. used a glove box. and we've thrown out 6 out of 12 jars so far. i can officially say that trich is the bain of my existence and i'm just not sure where we went wrong. the trich seems to be growing from the inoculation sites on the side of the jar? idk where we went wrong. we sterlized with the syringe after every jar.. i just dont get it :[ any ideas?

Ideas.....CLEAN EVERYTHING. Take a shower before hand, wear surgical gloves, isopropyl alcohol EVERYTHING, spray lysol FIVE MINUTES beforehand. You cannot be a mushroom cultivator without proper sterile technique. Good luck next grow.

steam sterilized or pressure cooked?
How did you sterilize the needle after each jar?
Was there a filter layer between the lid and band (ie coffee filter)

Crasher had a great question how did you sterilize? Pressure cooker? A good possibility is that you have a contaminated syringe. Also, how are you incubating? Incubation above 75 degrees GREATLY increases the contamination probability. I've had NUMEROUS failure due to contamination(trichodermia in particular) but if you hone your sterile techniques you can overcome it.

Problem 1- No pressure cooker
Problem 2- flame and wipe syringe with alcohol
Problem 3- get some tyvek/polyfill/coffee filters to cover those holes.

def investing in a pressure cooker for the next grow. i had a feeling steam sterilizing wasnt going to do the job. we did flame sterilize and wipe with alcohol. so i really think our sterilization practices after the jar sterilization were pretty great, but whats the use if the jars arent sterile?! so i guess we'll chalk this up to a learning experience and do better on grow 2? o and our incubator is set to 81? thought that was "ideal?"

I incubated at 80 in a TiT because my grow area was always 55-65. If your room temp is in the 70's, don't worry about it.

Hang on just a minute here. You don't have to use a pressure cooker with pf tek. You don't have to cover the holes with pf tek, other than with foil during steaming, which is removed after sterilization. You're supposed to flame sterilize between jars, but don't wipe with alcohol afterward. Simply use the needle a few seconds after you pull it from the torch. The first drop will cool the needle, and the rest will flow cleanly.
If the contaminant is growing from the injection sites, and you flame sterilized the needle, then your inoculant was contaminated. It isn't related to your sterilization procedure. RR

Guys, I think we missed the part where he says that the trich is at the inoculation points. If he was as sterile as he says then the problem could have been the syringe. He said that he didn't pressure cook. Something not necessary to the PF tek, (although recommended). If it was inproper sterilization of the substrate then it would have spread throughout at no specific point I'll give an example..
This is a pic of trich at a non specific area. Note the healthy mycelium growing from the inoculation point around the jar.
This pic clearly shows that trich began at dead center of inoculation point.
If he flame sterilized like he said... My money is on a bad syringe.
Just my .02

Sorry, didn't mean to misinform anyone. I'm so used to PC'ing it becomes strange when others don't. I always used filters over PF jars as well, just to be paranoid.
Agreed, nasty syringes.

My sincere apologies. I truly meant no disrespect.
If you purchased from a sponsor on this site, then I'm sure they will have no problem making it right for you.

Reputable vendors will attempt replacement given the circumstances.
Non-shroomery sponsors, however, are a different matter.

hehe its all good. not many of my kind on the site. wellllll they USED to be a sponsor apparently, but are no longer.. kinda bummed. i just went to take look at the babies and ive noticed that the 6 i have left are all cambodian, so the other 6 that we tossed were all the golden teachers, so i def think it was the syringe now. there looks like some colonization on the remaining jars, so im keeping my fingers crossed they survive. green used to be one of my favorite colors until this week..

if you followed directions to a t than it was a dirty syringe. Now did you really follow to a t. 1/2 oint wide mouth? 4 holes in the lid? wiped down the sides of the jars? 1/2verm layer cook for 1 hour in a pot or pc'ed for 20 mins? flamed the needle after every 4th jar? did not suck up any brf into the syringe? 1/4cc per hole? brf?
did water get into the jar during cooking? did you tip the jar from side to side after inocaulation?
if it was truely followed to a t than it had to be a dirty syringe Where did you get it? Spores101?

Well, there's no point being cynical to the point of elitism, man. You do it in a lot of your posts, and just because you've grown for however many tens of years doesn't mean you have to be so harsh to the people who haven't.
If someone wants to try harder to be sterile, giving them some pointers should be all it takes to get them to "clean up their act" (bad pun intended). Otherwise questioning their methods with the eye of a nagging stepmother is a bit much.
Smoke one and remember you were young and 'tarded once, too. 
To be a broken record for stellabella11, contams only at your inoculation points is a good sign of a contaminated syringe, provided you correctly sterilized your syringe between jars. Flame until your needle is red hot, and do it after every jar to remove any possibility of contamination between jars.

if one truely follows teh pf tech/mmgg to the "T" and they fail it is the syringe. There is no need to be "extra sterile" with that tech. It was developed so people who follow diretions can have success with minimal effort. Those who fail surprise me. It isnt hard, not even close.
