I did an indoor winter sunshine grow (window sill) just for the fun of it.
It was a hempy (with soil cap) in a solo cup, but it wasn't an auto.
I started it on Jan 19, 2016 and it was very slow....didn't preflower until April 6th ( I keep a diary on all my grows so the dates are accurate)
Anyhow, it wasn't primo pot by any means, but it produced 20 grams of smoke
