That's a good point and something a lot of folks don't get. Everybody isn't trying to make a living off growing. There's a lot of hobby growers doing only one or two plants at a time in a closet for personal consumption.
I thought the exact same thing until I ran a La Diva freebie. 48 days from sprout. Unbelievable so I kept checking my dates and I'm 99% sure I wrote everything down correctly.
UncleBuck likes to take pop shots so I'm just returning fire. I about have him figured out. I used to suspect he lived in his domineering mother's basement now I'm thinking trailer house and Indian reservation.
Go with some good LED's. I like the Secret Jardin tents but if you're growing for personal stash get the 3X3. That'll turn out more dope than you can smoke.
I like tucking mine up under my nut sack until the second node appears. Then transplant and grow as normal. You can grow hydro or soil using this germination pre-veg method, totally your choice.
