TC - how long does contamination take to show?

[StuartF]

I've just taken my first faltering steps into TC with three flasks of sundews and one of sarracenia seeds and a fifth with nothing as a control to see what causes any contamination, but I was wondering, how long does it take to show? In such a nutrient rich environment I'm assuming its not very long.

Depends on many variables, but normally anywhere from 3 days to 3 weeks. Sometimes it may not show at all (or is very hard to see) until the first replate.

Thanks for that - I guess I should stop checking it every ten minutes then

I'd agree with that. In my experience, some samples were quite clearly contaminated in a matter of days (and you will notice ), others will take a while. Check daily, I suppose (though if that's a significant effort, every other/few days.)

The fastest contamination I have had was in 2 days. Fungal contamination is very fast. Bacterial contamination takes a bit longer to appear, sometimes weeks. I agree with the above-said fact that sometimes the contaminaton doesnt show for months and then can spread suddenly for no reason and destroy the jar contents in 3 days completely. Sometimes the contamination is hidden and thwarted by PPM and other chemicals and can expand after replating to different medium. It is advisory to check the jars on a daily basis for the first 5 days after production. Then it is okay to check every 3-7 days, but that depends on amounts of jars and free time, of course:-)
