9wks of feed, no "Flush", and smooth as butter as soon as it's dry enough to bag (usually 6-8 days).
I wanted to point out that "Flushing" isn't essential to bringing out the purps. I have strains that get so purple they're almost black, but it isn't easy to do that (with these particular strains). One will turn out green (and half as frosty) if isn't done "just right". If the "mistakes" are greater than "1", you've got green fluff (with this girl). Had a Blue Dragon cut a long time ago. Her buds purp'd naturally (green leaves), but it wasn't as dense as I would have liked. Once I had her figured out, dense, frosty, deep purple, and leaves so dark they were "Black". No flush, temps weren't even all that low.
So, there's more to Purp's than just "temp n' flush". Keep in mind, terpene production dictates nose, trich count/quality, flavors, and COLOR.
