Common contamination timelines?
    #26672450 - 05/15/20 11:05 AM (3 years, 8 months ago)

What are the general timelines for most common contaminations? I've noticed personally for cobweb in jars, if a jar is infected I can see if (pretty easily since it'll be huge) within 2-4 days.
For bacteria, I'll notice it usually with 3-5 days. I've only had 1 type of bacteria (from what I can tell visually) so that's a very generalized statement.

I've only had those two contaminations, what's everyone else's input on this? When can we declare jars 'safe' based on how long they've sat without a contamination?

I recently had jars go green around ten days.

Bacteria on plates usually shows up very quickly, 1-2 days. Sometimes I think like a single bacteria must’ve landed on the plate cuz it’ll be a week or so since I made a transfer and this tiny tiny dot will show up.

Hmmm yea, that's kinda what I'm wondering about is the time frame when we can be generally 'safe'. I've had randoms pots pop up on jars that are 95% colonized after 7-10 days that look like cobweb, and I can't tell if they're just slightly whispy mycelium, or cobweb. Same with bacteria. Very colonized jars, just with a single kernel that looks iffy right towards the end...

With molds like trichoderma, you don't usually see them until after the substrate has been fully colonized, before the first flush.
