What made you think it was from Monster Genetics? Just curious.
My last order was larger, so in addition to the Green Crack was a bag labeled "Northern Lights x Blueberry". Up until that point, I thought the Green Crack might be re-bagged FastBuds, because they are the only breeder I could find on the site that carried that strain, and I was OK with that. Then I got the second strain, and like you said, no breeder they list runs that one.
I was not aware that NASC did their own breeding.
I'll let y'all know if they get back to me. Unless they impress me with the source, I'll probably plan on giving these seeds away, I've got no time for random stuff.
