well i have tga deep purple, sannies killing fields, and heaths black rose. the black rose is some of the most purplist (lol) weed i have seen but i heard it lack on potency. deep purple probably will not get nowhere near as purple as the black rose, so im putting that on the back burner for now. I plan on growing sannies killing fields along with ko kush x killingfields and crossing them with a black rose male. grow those out and cross with another black rose male. both purple up a lot so i expect to get purple buds with some good potency.
breed (SKF)x(BR) then breed (kokush x skf) x (br)
so ill have SKFBR and KOKUSHSKFBR
Then
(skfbr) x (kokushskfbr) = hopefully some potent purple piff
