They were the first place I ordered from 2 years ago. Overall solid experience, but I've moved on to different breeders like Oregon Green Seed, AKBB, Vashon and Bodhi. I've also moved away from Autos, but they were a GREAT way to start.
From Grower's Choice Seed, I've grown:
Northern Lights Auto--really nice, super frosty, delicious smell, not much taste, numbing, indica high. Grew 3.
Critical Purple Auto--dense, frosty, heavy indica (was my bedtime smoke for awhile). Nice generic 'berry' smell, but no purple on either one I grew (grew 2)
Hindu Kush Auto-Grew one. Much airier buds, less trichomes, bland smell, ok high. _meh_
Pineapple Express Auto- Taller than most others (4'), but budsites never fully developed. The 'buds' were like 2 or 3 calyxes thick, long and stringy. Could've made hash w/it, but I was loaded up with other stuff. Really interesting, sharp, smell.
AC/DC CBD- Grew 1. Another tall one (4'). Not listed as an Auto, but it was finished by mid August. Dry weight was a full pound. Nice, low THC smoke. Takes the endge off the pain and helps calm the mind a bit without getting too silly or foggy.
