I have 2 of these plants (unknown strain) and was wondering how long I should run my light for ? I have been running it for 16 hrs per day is this ok ?

No, its flowering - 12 on 12 off, unless its an auto strain. But she's surely flowering.

Also, they have just been transferred from outdoor soil to perlite 1 week today.

Ok I'll switch it to 12, thanks.
