Inexperienced Mycology

I've only recently, past few months, become interested in mycology and mushroom cultivation as a hobby. I've had no success thus far, but today is day ten on incubation of twelve half pint jars of Huautla I ordered from the spore works. So far, I've seen no signs of growth, however when opening the plastic box I store them in I'm detecting a feint "sour" odor, an obvious contamination but as of yet I can not determine which of the jars are contamed and which, if any, aren't.
That aside, today I receive my order of a 10cc syringe of the ********** Psilocybe Cubensis Corumba Brazil. With this I wanted to try my hand at a WBS to bulk substrate. Problem being, I do not have access to a pressure cooker and I've been forced to try using fractional sterilization. Anyway, to get to the point, is fractional sterilization, if I run a course of 5-7 days, 1 hr boiled then cooled for 24 and repeated, will this give me an effective sterilization?
I understand that it's impossible to entirely sterilize all the WBS in this method, but is its effectiveness worth attempting or should I just wait to try WBS to bulk when I get a PC?
I'll update this later tonight with some pictures.
****Mod edit: no vendor names please!

Hey man remove the vendors names from your post. You don't grow from syringes they're for microscopic inspection only. Don't throw people under the bus and give the rules a good read which you should do before your first post.

This has almost never worked for anyone who had to try it for themselves just to see if they could cut the corner. As you will find out for yourself this is not a corner that's worth cutting.

you NEED the PC to do grains.
Do the PF tek in accordance with the "lets grow mushroom" vidoes/tek http://www.shroomery.org/11432/Lets-Grow-Mushrooms-Pf-tek-videos
Follow this to the T don't skip anything or add anything. Get your first success then try other things.

Don't do fractional sterilization. According to RR, it doesn't work. What does work however, and to a satisfactory degree, is to steam them in a regular pot for 8 hrs.
You'll probably need to add more water during the cycle, so keep some water boiling in another kettle next to you.
Good Luck

8 hours without a PC will get them to the point at which the cubes have a chance to grow, but even still they're not completely sterilized. That's just the point at which you start to see a success rate happen.

..start to see a success rate happen? 0/10 is still a rate  RR claims to get satisfactory results this way, his webpage describes a 55 gallon drum used to steam sterilize grains for 8 hrs.
He has a freakin farm, I think he grows more than the rest of us around here combined

FWIW, I thought I heard what I posted from a RR post. He said he hadn't seen contams in something like 20k blocks of substrate, but just sterilizing the jars properly is not even half the battle to success when you first start out.

I don't get this.. You say RR said it does not work, yet he has 0 contams in 20000 blocks..?

They're only as sterilized as a PF cake at that point. It just takes 8 hours to get everything up to temp but it's still only 212 rather than 250ish. If you have really good clean spawn and a spawn at an appropriate ratio and have been doing things for a while you'll be successful but for a new grower an 8hour cycle for grain jars is the easier part of the whole thing. let alone the fact that he will probably do things like wipe with alcohol after flame sterilizing tools, shitty lids, leaving foil on the lids etc...

Say what? A PF-cake is just as sterilized as grain is, it just takes more timer or higher temp to "reach through to" the grains..
Of course, a PC would be preferable, but I'd still say to go steam for 8 hrs if pc is not an option.

Some endospores can survive 212
Your grain is fine if some endospores, most likely wont germinate or make if they did, but it's not fully sterilized.

Rice doesn't have endospores for the most part so it's cool to steam it but it's not the same as it would be if it were a PCed pf cake.

I think those posts are older than his 55 gallon drum. I don't think there's anything in those links suggesting what you're saying is right either. Try to read the link, then answer. Or search up newer threads where he says 8hrs steam is a-ok

I didn't say it wouldn't work, using the 8 hours, as it obviously has, even I said RR had 0 contams... I'm just saying it's probably not going to work for him since everything else is going to have to go smooth too. Reword my post for me and PM me it so I can edit it and make you happy.

if no pressure cooker, just do the pf-tek, better to have one bird in hand than 2 flying, chances are you are gonna fail at grains without a pressure cooker

Turning sassy, eyh? So you're advising against sterilizing grains because growing shrooms has a lot of trap doors? And it might not work because he is inexperienced?
If that's the case, why would you encourage him to spend money on a pressure cooker, when you're already doubting his abilities to grow? And how do you suggest he'd get his experience? By not growing?
This is just too dumb, coming from the guy who made a post about contams being an exaggerated problem and something we shouldnt worry about!
