I guess I'm high as I've read the thread and still try to figure out the conversation.
euhm they are gifted seeds.. just grow em, although if you don't want to spend the time and energy on something you're unsure about, buy something feel you can trust more.

+1 on the SIP recommendation.. most problems people experience with growing cannabis comes from watering & feeding if you get that sorted out with a SIP that's like most of the growing woes gone. Now you can focus on environment, guard for bugs & pests and just well enjoy growing weeds.
Autos can go all kinds of ways, they can go from mini lowrider plants to big bushes and from 6-7weeks seed to harvest to 11-16 weeks certainly outside all depends on the strain there's short and long flowering ones and the environmental conditions and light exposure.
