I never grew any of my mystery seeds out. I never understood the point of growing an unknown strain or unknown sex. Kind of can fuck everything up lol! My luck I'd plant 10 and get either 10 males or 10 auto flowers!
I popped a few from my first order just for practice I think, all of them but one was male and the one that was female was great, I think it was a hybrid, but your right its frustrating to go through a grow and not know what you have. On the other hand they way breeders mix up the parents over the years I am sure the Misty Kush I have from 6 years ago would be different from a pack today. That actually sounds like a fun test.
Well yesterday I changed their light schedule to 12/12.. I'll post a pic of my 4 plants. 2 on the right are in a small barrel hydroponic system. 2 on the left are in soil in autopot system. I'm laughing at myself for this being my first grow and using 2 different systems. What was I thinking? hopefully the unknown strain is a female.
