That cross is Wiz taking Gigglejuice, which is a full on photo strain, and crossed it with a fully auto Northern Lights(not sure what breeder the NL is). And he's only done the cross once, so it's what's known as an F1 cross. So of those beans a small % will have picked up the auto trait from the NL since it is the recessive gene. The rest will be photo-sensitive or maybe a little early on the flowering. To make it 100% auto, one would have to grow several out and only cross the ones that autoflowered. Then eventually at F5 I believe, it will become fully autoflowered. If I'm wrong Wiz will correct me.
