Does it matter on the mulch type? The stuff around here is mostly just barks or ceader (forgot spelling but some ant fungal wood)

Going against conventional wisdom... I don't even mix my spawn into my sub anymore. I have done some experiments that proves one of stamets points to a tee! Basically he writes how layering mycelium in a mat allows mycelium to "regroup" in a sense and explode outward (if that makes sense to you). I think these pics will show what I mean better then I can explain it. Notice how this blue oyster has exploded into crazy rhizomorphic growth outward from the centre 1" layer of grain sandwiched between mulch? that is 2 days grows from transfer. and the final one is 2 more days. so 4 days total.


shit is trying to escape the jar! I have never had performance like this in terms of leap-off and rhizo growth... 
EDIT: That second jar is not the same jar... it is a reishi jar I did. Can't find the other picture. But It looks exactly like Blue Oyster jar did! That is why I confused the two.

Bags filled with 4 quarts of freshly cooked grains are sterilized for 3 hours at 17-20 psi by this cultivator. The extra time coupled with the higher psi's ensures that cores of large grain substrates reach and are kept at the the correct temperature for the proper amount of time to achieve proper sterilization.
Colonizing grain spawn in bags generate a good deal of heat. Your condensation is a tall tell sign of the differentiation of temperature between the inside of the media vessel to the outside ambient temperature. Fluctuating ambient temperatures cause condensation. Solution. Keep your incubation/colonization temperature at a sustainable constant. Desired temperature range; 70-75F. For the incubation of large bags of grain spawn this cultivator prefers to incubate in the 68-72F range.
Ditto! did not see this post originally. but it is what I was getting at. Not enough time in the PC usually is the only way I will see bacterial contams. which now I almost never see anymore.

On my jars they climb to the roof of it but not that explosive . That's interesting there. I may give it a shot. You don't feel that's the temp flux in my place?

I have not tried any mulch aside from the scotts brand in terms of bagged mulch. It is the coloured variety and it uses natural colouring products. It can be found anywhere in North America apparently. I get mine at home depot or Canadian tire. which is basically a similar stores that is a big thing here in Canada.
Condensation is totally a temp thing. It is caused by a differential between the ambient and internal temp. that is why the condensation happens scientifically - I believe. I wouldn't stress to much about it. If you Give your bags a longer sterilization it will not contam on you. also if you lay them on their side and flatten them slightly the moisture will be distributed amongst more surface area and will not make such a pool. Does that make sense? basically you are spreading the moisture over a larger surface making it less of a problem in one particular spot (i.e. the bottom). I have found that colonizing jars on their side or a diagonal does the same thing and also allows for better ventilation.

Cool yeah larger surface area allows for more moisture to be recovered but also allows more to vent. The pooling though should be better. I think I will skip making an indoor swamp cooler this summer as temperatures will start dropping here and I can control heat much better.
The flux in ambient temperature makes sense too as that would control field capacity also water loves to evaporate when temperature flux comes into play. I just didn't think it mattered that much.

Bingo my friend! The major issue here IMO is the sterilization. I have found that most strains of edibles are monsters and as long as you give them that good clean substrate to start off with they will make it work in the end. Hell, If I were you I would still use all of that spawn sans the contam'd bits. God knows when I had bacterial problems that never stoped any of my edibles from fruiting sooner or later

OP Just to reiterate what drake said a few posts back, I see nothing wrong with that spawn. Yes condensation from temp swings but your spawn looks fine. If you want to be sure stick your nose against the filter and squeeze the bag gently. Sour or sickly sweet smell = bacteria.
