Lowryder Question

[Slackersulli]

Does anyone know at which point Lowryder start their 2 month lifespan?

Is it from seed germination or rather once the 1st set of leave show?

I have seeds that have cracked, but cold temps have slowed them from developing as quickly as I'd like.

I just hope I'm not losing a big percentage of their lifespan in the germination stage.

Thanks for any tips.
