Hey B.C. hope your having a great day my friend.I think I might go back to photo flowering for my next choice of seeds. I believe they will be better for training.
Also better control and recording of flowering time. I wasn't totally sure when flowering actually started with these blueberry autos.
But not bad for second attempt, and can only get better. More reading required.
You did a fantastic job on the auto, you will be great at growing photos.
I've never harvested anything as nice as your Blueberry from an auto.
If your that good at them you will be a pro with a photo.
As long as you can keep them in the dark for 12 hrs you have everything else down pat.
Stay safe
Bill
