I'm not sure if the autos will behave the same as the fem seeds, but I ended up with 100% germination. Harvest was 65 days from start of flowering. Veg time is totally up to you. I mainlined them and kept them purposefully slow in veg to space things out. Out of the 5 seeds I planted, I got rid of two before ever flowering, and got rid of one of the three flowered, leaving me two phenos that each put out around 1.25 oz of nice bud, and about the same amount of high quality trim. I'm still waiting on the lab test for potency to get back to pick the winner between the final two.
As far as space, they are moderately leggy. Nothing like pure sativa, but they definitely doubled in height in flower.
