I can't help you find the answers Sam. All I gave you was an observation being made, and these observations are now being duplicated large scale as we speak, though only this time without the pre-grow factor like I did other years before as well.
Just understand that I am here in Northern Finland where the sun will almost shine around the clock at june 24th, and way before and beyond it 'll be as bright as daylight in the middle of the night.
Currently, sun will set at 22:00 and rise at 4:45, so only almost 7 hours of a kind of 'dark' that is not realy dark. I can still walk our dogs in the forest at night and without a need for a torch. A hare far away running over a field can still be seen.
Apparently they are forced to shoot into flower in disregard of day length and due to their auto genes stimulating their flowering hormones, but therefore does a lack of shortening day length hours beyond a certain number of true dark hours
give them the impulse to continue flowering. (Just like all photo sensitive early's would do at the latter stage at our lattitude)
In that sense they would be true 'allthough late flowering' auto's for the 'shoot into flowering' factor, but still remain photo sensitve for the 'finnishing up part' of the blooming factor.
It is what it is, and if they were not like that then they would have had no chance to get this big as they do in here and produce lots of seed for the Finola company I suppose.
