You knowingly put it in there?:-)

BLACKOUT routine?
Same routine.
Might take a little longer with Nostoc.

We find it here growing anywhere there's some lime applied, it likes hard
alkaline soils.
Yes, lots of greenish jelly all over on sandy oligotrophic soils.

Is it like hard rubber green balls on the plant leaves? 

It's rare but I have seen onje case but it was not Nostoc, it was a green
algae. 
Unless you are certain, it may not be Nostoc from what you have said so far.
