I'll be honest, I had never heard it but its on a few of the dutch websites about White Widow. They dont say it about other strains.
This is a quote from what I read;
We suggest the final 2 weeks of the flowering cycle to turn the lights off altogether - or at least down to 8 hours. This keeps the flowers from regrowth and stresses the plant into giving up its last drop of goodness as crystal to protect the flower...try it!
I wondered about the hermie thing but they are so far gone by now, I dont think they could if they tried. They are sticky and very sweet smelling.
I was worried about the smell. Its almost perfume like. With a citrus twang? I'm no expert, but it doesnt smell like weed. But, when you smoke it, its brilliant.
6 White Widow - 4 god knows?
