Thats the whole point of RIU mate and this is, what i hope to be, my first successful grow
I had mine on 20/4 for a week once they went into the rockwoll then switched to 18/6 for around 3 weeks then i flipped 12/12 31 days from seed. I dont quite know when AF's are meant to show preflowers but they didnt untill day 9 of 12/12, 40 days from seed. If mine would of AF on their own i dont know, i wasn't going to risk it as i'm constrained by time and also want to smoke some for christmas. As far as yield decrease i am not to sure, I am hoping that because most didn't inherit the AF gene that maybe the northern lights genetics are more dominant in all area's including yield as the ruderalis genetics seem non extistent
Cheers for taking a nose through my thread, as for the cat it wasn't his fault, i was babbysitting a mates bitch and it was her, found leaves in her poo. Turns out it wasnt such a bad thing the most chewed plant turned out to now be my biggest and 3 of her branches/colas i've had to LST. But i have heard some horror stories about cats and grows.
