contam or not? this has a few growers stumped!
    #4630057 - 09/07/05 03:50 PM (12 years, 4 months ago)

ok, so in one of my bags I'm getting a spotty white growth throughout, it's the same color as mycelium, but definitely not branched looking. I've had this before, and i believe nothing useful grew from it (which probably answers my question!). does anyone have any ideas what it is, and how to kill/avoid it? where does it come from?

for comparison, i inoculated 3 bags with the same syringe, and also cooked all bags at the same time, so almost everything is the same, except the outcome.

this should be the contamed pic:

This is the reference pic:

thanks all!

wet spot/sout rot is what it looks like to me, caused by bacillus.

I agree. Bacterial contamination.

Yep, looks like Bacterial contamination.
Did you bought the bags with the substrate, or did you make those yourself ?
Anyway, review all your techniques and think if you're missing something regarding sterility - flame and alcohol on needles, inoculation process, surrounding environment, etc - all must be clean !!!
