Well, I plan on giving away some prints in the  near future so if op needs a replacement he can sterilize and reuse the vendor syringe but I doubt that it came dirty... it probably picked up a small amount of contamination during storage which sucks big time when that happens...

It could possibly be your moisture content in the bulk too causing you issues op.... it needs to be squeezed dry until next to no water drips out..

If you squeeze it and get huge water droplets it's to wet....i was making this mistake recently...now I press the hell out the bulk until no water drips out (once cooled) ... if you do it while it's still warm that's when it will become to dry....

awww hell.. i thought it was supposed to have a few droplets drip out when you squeeze and handful.. just a few, though, not a lot. maybe thats why my coir/verm started smelling funny.. meeehhhhh

just weird because it started smelling weird after only 2-3 days, and coir is supposed to be very resilient. and im talking about my leftover coir, with no spawn in it, so i know it's not spawn =p

not sure what the hell is up. smelled kinda like wintergreen skoal, dip.. gross haha.

How long has your bulk ingredients been sitting around? Also how are you storing them? Try to seal everything up and keep it isolated from your grow area. Also, coir and verm sitting around will absorb moisture from exposure and invite contams in. Ive never had a problem with spores from vendors on here being contamed. They usually do a good job, so thats the last vector that I consider if something contams. I would get new bulk ingredients and clean the hell out of everything, then start narrowing down where the issue is coming from. IE sterile procedures and pasteurization techniques. Agar helps eliminate the largest problem od not having clean spawn.

the coir/verm was prepped in a PC, and then after i used half, i sealed the PC back up and it sat there for 2 days, then when i went to put it in a bag to put in the fridge, it smelled like that. so idk.. again, this was leftover stuff, that didnt have any spawn added to it. but idk.. weird, right? i mentioned this in another thread, so now i feel bad that it's getting talked about in both. ill keep it to this one.

That shouldn't be a problem. What I was asking is how and where you are storing the bulk ingredients before you use them? How old I the coir and bag of verm? If you pc'd your bulk subs then you basically sterilized it killing the beneficial nutrients and organisms. Pasteurization doesn't reach that level of killing all endospores.  Either way proper pasteurization should stabilize the mix, so agar work with spores is why we do that ahead of time to rule out contaminated spawn.

oh, well the coir was in a brick, in sealed cellophane. sat it in my closet. got it about.... 3 weeks ago, i think. not sure how long it sat before i bought it, though.

and the verm was in a bag, that i got like 2 months ago, sitting in the same closet. bag was opened, and has tiny holes in it. came like that.

i just assumed the stuff was fine to sit like that, though, being so resilient.

then i just mixed a half brick with verm in PC, dumped boilign water in, put sealed lid, let sit for 2 hours, then let cool, then used half, and left the rest sealed in PC.

That all sounds okay to me! As long as the stuff hasn't been sitting around outside for a year in a dirty garage or shed lol. Also I thought that you said you pc'd the sub which is a big no no. I guess the only other options is the spawn is contam or try switching up how you are pasteurizing subs with a different tek/method.

nah, yeah i didnt PC it, just used it do mix and dump the boiling water in.

and the coir/verm that didnt have any spawn mixed into it is what smelled. so its not the spawn.

i mean, my pawn probably does have a little bacteria in it, but what im saying is that even the leftover sub, that had 0 spasn added, is what smelled. so i dont get it.

but yeah, ill try a different method to prep it next time. just hope my Big Gulps i made with that sub will turn out ok.

:thumbup: coir does have a slight smell when pasteurizing to me, hard to describe it but it smells like burned soil or something.

hmm. it did smell just kinda like warm dirt or something, when i finished the prep. but then when  i opened it back up couple days later it was different. like kinda slightly like wintergreen dip or something. thats the closest i can get to the description. really strange.

Hmm could be the coir vendor or manufacturer treated it with something. It's not that cheap ass eco-earth coir is it?

Cheap ass Eco earth coir?

In my experience Eco earth provides a super quality product that performs admirably as a mushroom substrate.....I've literally never had a problem in the three or so dozen bricks of Eco earth I've gone through in the last couple years

The one brick I bought was a pos full of too many thick husk strips and trashy looking. Ever since then I've been buying 350-400g bricks in bulk from a vendor that imports them from India. The coir seems a lot cleaner, packaged better, and pressed harder.

Yes they tend to vary in weight often that's why I've always weighed out my dry coir before expanding. Some teks are rather vague and just say a brick, which confuses new people on what the usual brick size is. I have a bunch of mini monos going now a days and I typically stick with the same spawn:sub ratios now after experimenting over time.
