Do these bags look ok? I'm new to this and i'm testing substrates mixes.

I can't seem to get good results with wheat bran suplementacion, they seem contaminated with bacteria because they have a very slight sour smell that get stronger in bags that have more. These bags were inoculated with corn grain spawn about 10% dry weight. Steam sterilized in a 220 liter drum over a gas burner for about 12hs. All bags are 500g total dry weight, poplar sawdust + supplement(if any) and 70% water. Bags have been colonising for 8 DAYS. ---------------------------------------------------------------- 100% poplar sawdust (these are a kind of control group)
 ---------------------------------------------------------------- 10% wheat bran + sawdust
 ---------------------------------------------------------------- 25% wheat bran + sawdust
 ---------------------------------------------------------------- 50% wheat bran + sawdust

 All the bags with wheat bran have a bit of a sour smell, is this normal? my guess it's bacterial contamination, like they are fermenting or something. ---------------------------------------------------------------- 50% grape pomace(the residue from wine making that is sometimes used in as fertilizer) + sawdust, the bags look wetter because the pomace doesn't absorb water to well.
 ---------------------------------------------------------------- Any advice, i can't seem to get soybean hulls so i have been experimenting with what i can get. Which bags look better? imo the 100% sawdust bags look the best but in my last attempts i have only gotten a BE of 20% from them(only first flush so far) I'm thinking of trying just adding corn grains mixed with sawdust, i'd imagine while slightly more expensive the corn grain would be good a supplement since grain spawn is in itself a supplement, right? but they wouldn't be previously colonised and just mixed in with the sawdust. Please comment and tell me wich bags look ok for an 8 day growth time.

I will try shaking but these bags are pretty thin so i risk puncturing so i'm going to have to be very careful, still i don't think this will solve the problem because the slightly sour smell appears fast. I have been recommended to cook for 24hs, 10% wheat bran, 2% gypsum(plaster of paris) and use 50-60% water with 1% lime in it. Hope this will work because i don't know of any other readily available supplement to use since i can't get soybean hulls.

it looks like your substrate is too damp. The bacterial attack speaks for it. above you also wrote that you used 70% water ... as you just mentioned 50 - 60% better

Yes, i just hope it will work because i don't have other supplement choices apart from wheat bran because i can't get soybean hulls and i know that those are considered the best, any idea how they compare to wheat bran for BE?

Wheat bran is fine! Wheat bran is the number 1 upgrading substance here in Europe. But I don't use wheat bran either because my substrate mix (pellets) with the fine / sticky bran becomes too dense. But there are also coarse bran that should be cheaper and better. But there are no coarse bran in my area. and soybean hulls, of course, neither. I live in Austria. .. with us there is roughly only: spruce forests; Cows, milk and beer. In desperation I used horse feed and chicken feed ... After a long search I found barley meal. But it is not perfect.
I don't think soybean hulls are better than bran. doesn't bran have more nutrients than soybean hulls? Masters Mix (50% / 50%) would be too much with bran.
I think coffee bean hulls could work well too. .... Maybe in your area...?
and .... I would personally advise against the corn kernels. There were corn kernels in the chicken feed. I don't think the high starch content is beneficial. Whole corn kernels are too big anyway.

I live in Argentina, Mendoza where there mostly wine production so i can get a lot of dry Grape pomace and i already am experimenting with it, but on my test bags i got contam and i used too much water, gona try again because if it works it would be great. Also there is olive oil and breweries so i'm going to experiment with their byproducts also if i can get my hands on them. Im sure there are a ton of waste products one could use but since i'm not familiar with al the industries it's a lot of asking around for the stuff and then testing and hoping some give a decent BE and it's all a very slow process.
There is no coffee bean production here in Mendoza that i know of.
I have read that dense substrate is bad but I don't really get it, oysters naturally grow on wood, you can't get any more denser than that!
is it because it's slower?
Also since masters mix is HWFP that are basically really fine sawdust when hydrated and soybean hulls are probably really flaky or don't hold moisture well the mix is probably really dense also or am i wrong? haven't really seen it apart from videos.
All the HWFP i can get are from pine, i know some mushrooms like p.pulmonarius can grow on pine so maybe i will try it out.
Aside from being more practical is there a difference between HWFP and sawdust?
I'll let you know how my bags with corn kernels turn out. So far they are doing ok i think.

Wood is dense, but since it is, it can only absorb the right amount of water for mushrooms to grow. The problem with dense substrates that WE make, is what you've already said - too much moisture. I believe you have already figured out your problem and re-trying with less moisture should work.
The main difference I've seen between HWFP and sawdust is that sawdust is much finer, the HWFP I get are much coarser, but this could vary if you get different sawdust or pellets. In general though sawdust is usually much finer and, for that reason, a bit harder to master the moisture content perfectly, but it just takes some trial and error (or math).

They were running out of oxygen, the filter didn't allow enough air exchange, that was the problem!
