I know yellow is one of the stages before turning red. Are all the pods turning from green to yellow? I guess I don't know why there couldn't be a yellow scorp too!
There are yellow scorpions available now. I know some "red" scorpions in the past turned out yellow and I've also had scorpions turn completely yellow before going red
I grew both. I got the yellow Scorpions from a friend who got them from a CARDI representative. Not as hot as the red strain, but an absolutely awesome producer and one of my all-time favs.
