New Grower 12/12 autoflower. Yes it can be done.

Just a note for other growers searching for this info. I was worried about flowering my auto under 12/12. I vegged under 20/4 and flowered under 12/12. The end result was excellent. I may have given up a little yield, but I'm not really sure. If I had vegged under 12/12 I doubt I would have this size of a plant. This thing is pretty heavy for an auto. This flowered under 150w hps. This pic is 75 days from seed, Northern Light Royal Queen Seeds.

Good Luck

how long did you "veg" her @ 20/4 ?

i was expecting to see a plant triple the size

Beautiful Plant!
Definitely lost quite a bit of yield.
Auto's can definitely be grown under 12/12 but yield suffers significantly.

With TD I go from 6z per plant to 2.

Peace.

I thought she was pretty monster. She is 32 inches from the floor to the peak... She was under 20/4 for maybe 4 weeks. 6oz from an auto? that's a lot of basil...
