flowering q's for pot professors

Evening all ( oops! )

These questions may seem obvious to some but I can't find reliable data on them anywhere. If a person grew some plants from unknown strain of seeds outside ca. 56 degrees north ( Scotland ) in May and now they're about 5 feet feet ( look like indica, i'll try to post some pics. if requested ). This person decided to give them a 14 hour night with plastic sheeting in order to force flowering two weeks ago and some pistils appeared within two days. Now this fellow is becoming fatigued with the travelling and stress of visiting to his o/d grow twice daily and is being tempted to wonder if he can leave the ( all except one herm. ) girls to their own devices to regain his sanity. Can he do so or will the buggers reveg.?

Also if seeds were produced and covering was abandoned, what would happen to the growing seeds. I have scoured the forums and the books and can't find this scenario - the moral of the tale ? Next time buy o/d seeds, oh my. thanks for reading.

yo, if u started in may and there outside then flowering should happen naturally , at least it did for myne maybe its different in the UK im on the west side of canada . As the days are getting shorter my plants are starting to flower (late August) , so i would think yours shud do the same. pce
