effects of over spawning and under spawning shiitake bags

what happens when you use an inconsistent amount of grain spawn in your shiitake blocks? what are the effects?
Will too much grain spawn cause mutant fruits? but will colonize very quick? will too much grain spawn cause lower yields?
I've been haphazardly dumping variable amounts of grain spawn into my bags. my thoughts were grain is free, there fore spawn is free, lets put lots in.
now, I've started a new regimen. 1 cup of spawn roughly per bag. I've been making spawn bags of 6lbs wet grain. i recently did a spawn run and made 16 4lb bags with 6lbs of grain spawn. i have also adjusted my substrate recipe and acquired a different type of sawdust.
some colonized blocks (2weeks) and the beinging of the current spawn run in the back.

3 6lb bags of colonized grain spawn currently in cold storage

Some good questions here and I would also like to know about this. Staments recommends using sawdust spawn for shiitake. Ive just made 6qts of shiitake grain spawn. I was planning to use 1q per 5lb supplemented sawdust bag. Will this work?

1 quart of spawn per 5.5lb block is a good amount of spawn if you're not supplementing otherwise, although most prefer to supplement with bran, sterilize, and use a very small amount of spawn.
Yes, too much supplementation/spawn can cause mutants sometimes.

Thanks for reply. Such a massive learning curve! Another grow doomed! So would you suggest I just pasteurize un-supplemented sawdust, mix with 1 quart oat grain spawn and seal in a myco-bag? Open air? Or will I still need to sterilize the sawdust? Im working out of a SAB, so thats why I planned to use 1 quart jar to spawn each 5lb bag. Trying to spread the grain out into multiply bags could be problematic and open to contamination for me. I dunno Im totally new. Im open to any suggestions and advise. Thanks again.

Yeah if you're not supplementing you can just open air spawn, no need for SAB at all 
Used to do it all the time when all I had was a SAB. Too much of a PITA to work with bags inside them...

Thanks for the tip. I think my SAB has enough head room. I think I might give this a go however I need a recipe. I'm reading crazy amounts but it's always conflicting information. Staments uses 20% bran but inoculation is via sawdust, RR doesn't go over 10% bran but uses a whole quart jar of grain to inoculate and Evilmush666 documented alot of grows and was getting mutants on UN-supplemented sawdust with anything more then 200ml's of grain spawn. I understand things will vary sawdust to sawdust, strain used and im not clear on what size bags RR uses. I guess I will have to trail and error. Have 3 x 5lb bags pasteurized and ready to go. I think I would rather sterilize because contamination rate will be lower. Could you suggest a recipe for 5lb bag? and how much grain spawn should be used to inoculate? Thanks again.

Can't help much with recipes. I never supplemented, just bucket-tek pasteurized fuel pellets and open air spawned a full quart of spawn to each 5.5lb block. Only rarely got a mutant here and there, nothing that was a problem.
