My jars are 90% colonized but i noticed some discoloration on the bottom of a few jars. Its a grey clay color. Anyone ever seen this? It looks like the myc stops where the other color starts so im assuming its contam. Also my jars are pretty wet, perhaps thats the reason. Heres the pics, sorry about the quality. ALso i flipped my jars yesterday and some of the "clay" stuck to the bottom of the jar so its harder to see.
I looked at my jars today and the mycelium has taken over nearly 75% of the wet spot contaminated area! Im going to be birthing my cakes tomorrow, i think i'll birth those also but keep them isolated from the rest. I'll let ya guys know how it goes.
It's hard to tell from those pics but it looks like the substrate is packed too tight. If that's not the case i would be more inclined to say it's contamination. An advice. If that spot is covered with mycelium, that doesn't mean the contamination was killed, it might be alive, hidden inside the cake. That could prevent the cake from fruiting and even if it does fruit, it could be dangerous for you to consume the mushrooms. Try cutting the cakes in half and inspect the cakes carefully to see if there's an sign of contamination. Scoop out any contaminated substrate, dunk in some h2o2:h2o solution and case it.
AFOAF had a jar that looked exactly like that. The jar did eventually colanize 100%. Being a man of prudence, he dunked the cake in a dilute h2o/bleach solution for a short time, followed by a 12-hour h2o-/h2o2 dunk. It looked okay. He crumbled the cake and found no signs of contamination. He then cased it a cut 2-liter coke bottle. Seems to be going well.
Don't throw it away. Not yet, anyway. AFOAF thinks that the substrate was over-saturated.
