Opinions Wanted - Spawn Bags , misc problems and sealing

I have been working with spawn bags the last few months. Usually doing a rye jar grain to bag transfer. A good number of the bags turn out fine fully colonized. They always seem to get a good start but on many of the bags finishing their coloniztion (in the latter stages), I get slimey rye sections (I think this is the stuff giving off an unpleasant oder). I notice that I do better with bags that are so 30 % full as opposed to 60 % loaded. Is a moisture build up in some parts of the bag causing this and should I turn and shake the bags more often ? Does having larger bags mean more opportunity for the bacteria before full colonization? I have read about the bacteria situation with endospores and such but I do the thing where you steep the grain overnight then simmer for 45 minutes before bagging. I also pressure cook at 15-20 psi for at least 2 hours. I thought all of these efforts would eliminate the bacteria infection. The one problem I did have at first was getting a good seal on the bags - I started trying to seal the bags with the natural fold still in them - then I started pulling the bags at the top so only 2 layers of plastic were involved - that was better. Still have some of the slimey spots on occasion though. Any thoughts. thanks, f

I have tried this way before, and i have never been able to get rye to fully colonize without having your problem. I don't know the solution to your question.
I soon ditched that method and rye all together, and went with a Hpoo/WBS mix that i have not even seen a problem with.

thanks - could your share your hpoo/birdseed recipe and where do you get your hpoo. I have orderd from tenn studd for pan cyans. I had some success with those and was worth the try but I also had a ton of failures too. thanks, f

Using Blue Helix's write up in the FAQ section on spawn bags, i use wronguys' recipe which is....
"Okay, I'll share. Now the ingredients were compiled with the help of Blue Helix and Agar. There is nothing exotic in here, but it has a good nutritional profile. This recipe is for 4 large filter patch spawn bags. It will fill them within 2 1/2 inches of the bottom of the filter patch and lays out perfectly in 19 quart containers with a substrate depth of 3 1/2 inches.
The recipe is as follows:
48 Cups of horse manure (shredded) 24 Cups of vermiculite 16 1/2 Cups of dry WBS (do not soak or simmer) 4 Tablespoons of dry Kelp Meal 6 Tablespoons of Canola or Vegetable oil 21 Cups of water
Thoroughly mix all dry ingredients together. Now, add the water and mix again. Due to the human error factor on measurements, you may consider adding only 18 cups of water to begin with and adjust it from there. However, I have found that any measurements that are off are negligible in the moisture content.
After all the water is added, test your moisture content by giving the substrate a hard squeeze. You should only be able to extract a few drops from this, not a steady drip. If you find that your substrate is a little too wet, slowly add vermiculite until you get the right consistency. If you measure everything correctly this should not be necessary. The moisture content needs to be slightly dryer than normal to allow for the liquid culture you will inject later.
The final step is adding the oil. I prefer to add the oil in after the water has been added. I find it's much easier to mix in and doesn't stick to the substrate in one area or clump. Mixing the oil in with the dry ingredients will surely clump on you.
Load your spawn bags at the same time and make sure they are as even as possible. Now it does not matter where you mix this. I do mine in my garage. I know I'm going to sterilize the substrate so contaminates are less of a concern. Follow the tek by Blue Helix to complete it. I personally PC for 3 1/2 hours at 15 PSI.
After they have cooled just inoculate and wait. "
BTW I do exactly as described and use 140ml LC injection straight into the bag.
All have worked out superb, every bag i made. No mess with contams so far.
I get my poo from various sources, but its always leached and well weathered. It does smell like dirt and it is indeed shredded. THis is not pasterization remember, this is sterilization of the substrate.
Enjoy.
