Richard suggest finding sativa pheno in f2, and work from there, he's doing backcross to congo mother... well i don't have any congo, but i have some of Sam The Skunkman's Original Thai Haze, which i might pair a sativa f2 with.
Lookin hot ´Mo!! Very happy to see someone reproducing this cross. From what ive seen and heard this cross is not dominated by the DC as per usual. Its more of a nice 50/50 mix between the congolese sativa and the broadleafed afghan. The taste and high should be very complex and a perfect blend between the parents. Much respect for takin on this project wich ill be watchin with interest. Spread em far and wide!!
