+1,... don't alternate your light schedule.


I'm starting to think that my Grandaddy Purp strain is sensitive to the sharp cut off from dark to light and light to dark.

Outdoors, the sunlight gradually fades in to full, the gradually fades out, takes about 1.5-2 hours, and the light cycle changes ever so slightly every day, taking me into 12-12,.... My INDOOR GDP hermed ever f'n time I tried it,.... Out door,... Nothin, Clean as a whistle.


Why? My guess is that my indoor lights are warmed up in about 3 minuets, and off in about 3 seconds, and the shift from 18-6 to 12-12 was only interrupted by 36 hours of utter blackness.

Works great for most strains, but that one's a picky bitch.

Good luck and welcome to it!
