Those Low 2 x AK will be huge!!
I never grew these, but my AK 47 auto did grow fast...and it flowers faster than the Low 2, so you should be really happy with these in your garden, bro'!
I noticed that with my AKs, everything about them was explosive, they germed faster, all very uniform, and were a week ahead of my WR autos (if I remember the AKs flowered at day 10, which is fast!!). Then the WR flowered around day 16-17 and the Lowrder 2 last. I never thought "gardening" would be this fun! potluvr
