same happened to me first time with straw.

was it properly hydrated?
did you tuck the edges in properly?
did you sterilise the tub first?
clean hands?
did you keep inspecting it while it colonised?
good aeration while it colonised (eg. clean fork holes)?
any chance of dirty air blowing in?

next time, be meticulous, and case it as soon as you dare. it's the frayed straw edges that go green easiest, especially the dried out ones.

good luck take 2 :kiss:

if it was too wet, or the pH too low, or not enough air exchange, you could have easily created a great environment for mold growing.

how wet was it?

what was the casing made with? (50/50 of what? was there a pH buffer)?

did you fan it out frequently?

how clean was the room it was in?

It can be frustrating to manage not to lose all the cultures to pre-casing contamination, and than have the casing contaminated... That's why I never understood why people use casing with organic ingredients. There are some efficiency issues to be considered when using a non-organic casing layer, but I think its worth the cost. In this very case, I would definately recommend you to try something like the TEK I use: I wrote about it in the "Perlite-bed TEK" thread, at this forum.
