IDK about OJDs GDP but I would imagine it would be similar,if not the same plant used in the PNW crosses by estes/DVG..from experience growing 4 of the estes versions (early release before the BS) 3 out of 4 plants from every cross went purple at optimum indoor grow temps (max 26c @day,min 20c @night)..but purple isn't just a colour...the GDP crosses that I have grown all have a very particular perfume/floral note which I find alluring..think somas lavender on steroids..or if you haven't smoked that...think about walking into a room with lots of old ladies playing bridge..that 'old lady perfume' smell..I know it doesn't sound good but it is..I think it's myrcene (sp) which is the terpene these type of aromas come from.
ojds cookies and crosses stink like hell,,,,,very potent flowers,,,
need a bit of training to get them to yield,,,
i take the rainbow jones and its crosses over them....
ticks all the boxes for us,,,s2
