Name That Contamination! (First Post!)
    #21715064 - 05/23/15 06:06 PM (8 years, 8 months ago)

Hey guys, Im Brandon Pena (this is a pseudonym)

I've recently started my first cultivation. I've inoculated 5 jars with a Golden Teacher spore syringe from thesporedepot. The substrate was made from with brown rice flour and vermiculite.

After about a week, under stable conditions of 75 to 82 degrees Fahrenheit, all 5 jars have started colonization. However, one jar shows sign of contamination. Although I have checked the forums and it is probably blue mold, can you guys give a noob like me some information about how it occurs and advice to avoid it from happening again , if my other jars are okay?






I added a picture of two jars, a successfully colonizing jar with white mycelia, and the jar in question.



Thanks so much!

Trichoderma. It could be from a straggler in the syringe, if you have a dry verm layer. Syringes aren't 100% clean, which is why lots of us germinate them on agar and then cut the healthy mycelium out away from the trichoderma. That way you can drop clean mycelium into your jars.
