+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!
canniwhatsis Reviewed by canniwhatsis on . 18/6 and 24 hour on and off? Hey guys, im just curious if it would screw anything up or damage or whatever to my plant if i were to do 18/6 one day and then the next 2 days the 24 hour method and then after that back to 18/6 .....etc. and the reason i ask this is cause i want to do 24/7 but it would still be to much electricity for me to use even tho im using cool white t12 florescents, and want to get the most i can so i figured one day 18/6 and the 2 days 24.....thanx for reading and please get back to me soon fellow Rating: 5
