Because of the genetics (chems) I expect no less than 70 days. Throw some haze in the mix and they tend to go even longer.
I know my description is broad too but
because these are F1s it depends on how much influence the mother has.
My TNT for example had two very different pheno expressions. Looks, smell, structure and finishing time. One finished in under 63 days and the other went to 78.
But for me, that's what I love about F1s and hunting through packs. If I wanted uniformity, I'd just run clones. For me, that's about as interesting as watching paint dry.
