I've talked to the guy who got me started and a couple of other people, and they said that it make your plant think that the season is about to change sooner, so they try harder to make more th(. This is my first grow too. Right now I got two northern light+ak47 flowering in week five. i just put them in a 11/13 light schedule. Im going to take away 45 min. a week for week six and seven, and see what that do. Hopefully it'll make them be some strong ass halfbaked type shit.
I took a couple clones form them before I started cloning, so if something goes wrong, I'll correct my mistake next time. also if you go on youtube, type ready set grow and it will give you a little info too.
