My last white russian crop spent their entire flowering life under 14 / 10.

Why wait til the last 2 weeks? You can do it from day one.

And my personal opinion, is YES, it does make the flower more potent...without question.

It "MIGHT" extend the flower period by 10 - 14 days.

It "DEFINATELY" makes the more pure BUZZ.

If anything, you want to reverse that formula....14 hour days then 10 hours days the last 2 weeks.

THis will quicken the final prduct. Plus 14 hours of light in flower will help keep the plants fans alive and kicking which in turn power the plant some more.

Try it, you'll like it.
