don't get your panties in a bunch boys. Blackdaddy has great hybrid vigor. i find when you move colombian genetics north and expose them to cooler temps and appropriately long growing season most Colombians show great color. The other Kens GDP cross with supersilverpurple has been very sucessfull. hopefull that purple gdp will impart the colored genetics into a strain that also has the propensity to color in temps. Blackwreck was a stone cold colombian, and in most other crosses has shown a predominance. best Tipz
