I have grown G13 Auto AK twice and love the strain.
It has a lovely smell as soon as its dried, which only gets better as its cured. It looks dank and is covered in THC. Its not the biggest producer but it is still acceptable. I averaged about 1.2 oz's with this strain using a 600w HPS. I think the smell, taste and potency easily make up for the yield. The strain itself isn't the most stable strain on the market, I had a lot of different phenos. Some were short and stacked, some were spindly, some had 14 tops, others had 4.
I would advise anyone to grow this strain. Start a journal and let us know how it goes. Good luck and enjoy.
