help after failed grows
    #23930835 - 12/15/16 08:31 PM (7 years, 1 month ago)

I am no good at growing mushrooms apparently. My first couple grows went great even despite the fact that I had no idea what I was doing. THis made me think growing mushrooms was super easy. But since then I have had problem after problem, from green mold taking over the cakes to bad spores, to contamination which seems to be my biggest issue of as late.

I dont understand why in my first grows I followed the same procedure and only had one jar contaminate. Now, my jars are contaminated after only 3 days after planing the spores! They contaminate before the mycellium even begins to grow! Which each of my last three grows the jars have contaminated with this gray orgranism and in each subsequent grow it happens quicker. FIrst time they contamed after about 2 weeks, second time after about a week and this most recent time in only 3 days!

Can someone tell me what I am doing wrong? I am using pf tek, brown rice flour and vermiculite cakes pressure cook on medium heat for 45 minutes and inoculate using the oven method wearing a mask and sterilazing syringe after every 2 jars.

Are you inoculating in open air? Build a still air box if you are. Other than that there isn't much you can do, syringes are dirty. It's luck of the draw with PF tek.

Oven method is not a good practice, it actually pulls room air toward it and circulates it. Use a sab or a glove box.  It could also be the syringe/s you are using are very dirty. Have you changed vendor's or anything?

I fucked up my last 2 pf grows. Said fuck it and attempted bulk and almost all of my grows have been solid since. Must've been the mushrooms telling me to stop thinking small :grin:


--------------------
How to get started in bulk:
Presto 23-Quart Pressure Cooker
BOD's Simple as FUCK Still Air Box
PastyWhyte's Easy Agar Tek
Munchauzen's Cultivation Video Series
How EvilMushroom666 Prepares His Grains (I use jars with Synthetic Filter Discs)
What is G2G? (Grain-to-Grain)
Damion5050's Coir Tek (I use 5.5 - 6 quarts of water instead of 4. Also ignore step 13 and ignore the monotub completely. The only purpose of this tek is to show you how to make a simple substrate. I also add gypsum to it but not necessary)
Spitball's Monotub Tek (A liner isn't necessary but is useful)
Use 6500k lights throughout the whole process. When you wake up, turn the light on. When you go to sleep turn the light off. It's as simple as that.

along with what everyone said make sure your spores are clean and coming from a well trusted vendor.

A few easy things you could look into:

1.) Buy a 66qt plastic tote and cut holes big enough for your arms to fit in.  Do all your sterile work here.

2.) Make sure you're using your pressure cooker correctly.  I turn mine on high, getting a steady flow of steam for about 10 min, then turn it down until it reaches a steady pressure...then I start counting down.

3.) Flame sterilize after every jar.

4.) Don't count on the syringes being clean.  Make pasty plates (takes no time at all--10 min. of work/an hour of cooking/a few hrs to cool) or order some pre poured agar plates to drop spores on.  This way you'll know exactly what you're inoculating with as you'll see any contaminants clearly.

also 45 min of proper pressure cooking should be enough.  If you're just steaming, then you'll need 90 min

Good call mushboy. Don't know how I missed that.
Why on earth would you ever reccomend a shorter PC cycle to sone one having contamination issues? And fyi 60 is bare minimum. 90+ is reccomended

1. If you don't have a pressure cooker, get one
2. Make a still air box and use it
These two steps eliminate most problems.
3. I never found PF Tek an easy method at all ... others do and I understand that ...  Having said that, if your cakes are contaminating, you've got bad spores or you aren't sterilizing your cakes properly. 
4. Try V-tek method  ... https://www.shroomery.org/forums/showflat.php/Number/21390984 ... as it's the easiest method I found. 
5. Learn how to use agar ... pasty-plates are easy and cheap ... as that will dramatically reduce your contamination risk.

You guys are right.  45 min is not enough time, so thanks for correcting me. I meant to say 60 min, as that's what I have always done for cakes in the past.  Haven't done cakes in awhile though.
OP, I think if you make the changes listed in the few replies you've received so far, you will see some positive results.
