I also found some possible strain choices

I am doing an indoor grow and its a sog so short dense plants are ideal ... mainly ones from afgahni heritage.

I came across

Mendo Purps

Purps x Afgahni

Bluemoon x BOGBubble

Lavender

All have afgahni herritage and are short and stout but right now the mendo purps looks like the most purple colored bud but hopefully I can find some pictures of cured bud to compare ... lavender also looked like a good indoor bud becuase I remeber reading an article saying Purple Erkles herritage was believed to have came from Lavender.

One of these natrually purpling strains combined with enviormental factors needed to produce the purple coloring should give me some nice solid violet buds.
