AK47 autoflowering

Hello , i am about to start 5 fem ak47 auto's, i just wanted to know from any1 that has grown this before what the best light cycle is to use cos i'm being told 18/6 but the all the sites that sell them are saying 20/4 , also i have some vintage bat guano left over from a previous grow was wondering if thats gonna be ok to give them? Growing in multi purpose soil and a 250w hps all the way through.
Thanks for any help and if any1 has any pics of their ak autos would be very grateful.

no ak autos, but im doin shortryder and 20/4 is working great (some doing better than others). i think all plants need some darkness for development.

ok then thanks, what are shortryders btw ?
Also are you going to be using any nutes on them?

NIRVANA AUTOFLOWER. yeah im using nutes just started bloom nutes this week they're 23 days today.
