Well I've recently dipped into autos myself for the first time, tried out the lowryder2xak47 auto-fems. what I found was this- Great for someone with space limitations. The lowryder/aks I got were supposed to top out at somewhere around 24". Now, I combined that low stature with lst to create a decent bush, 11" tall, that weighed just shy of 4oz's WET. Lighting is best at 20/4, but they will flower under any lighting cycles. My understanding is that u can hurry them up a bit with a shorter light cycle, say an 18/6, but they dont yield as much. Myself, I have found them nice to have in my closet flowering while a totally different strain known as 'harry the 8th' vegges away to her motherhood at the same time.
