Yes, fluctuations in the light cycle will obviously give you herms, but on top of that, it will cause it to flower slowly, or perhaps never flower to its full potential. You need to tell your friend that a 10 dollar timer will save him loads of aggravation.
TheGanjaKing420 Reviewed by TheGanjaKing420 on . Sacra Fresca flowering Problems I have a friend growing a single feminized sacra frasca plant under 48" lights. (its growing amazing, no light issue here) its been under a non-constant 12/12 cycle for over a week and a half that varies from 10-14 hours b/c he has no timer. besides the danger of a hermi from that, are the light swings a cause, or a nuisance?
