Going from cold to warm climate

[Humungus]

Good day farmers , I have a question. June 1st I transplanted 4 week old Afghany hash plant from seed . It’s is now September 8 th and still not flowering , getting very cold here , 2 to 6 Celsius at nite , so I will move them indoor to force flower , will there be any problems doing this other than pests ? They are in 20 gallon finer pots with organic farmers crap soil , Thanks

Strange that they aren't flowering , I don't see any problems bringing them in from the cold.....
