Yeah I wouldn't be as interested in the plant if it were a hybrid.
Ace Malawi x Ciskei would be amazing. Malawi is the most aggressive strain I've come across.
It probably is a pure landrace but the phenotype is very far from anything hazy. It's got dark medium width leaves and I can't get it to stretch, not that I want to but it takes some vegtime to get a good yield.
I've been thinking about a malawi cross too, but I'm not too interested in the overpowering Ace version, I'll probabably use the African Buzz instead if I do. Zambian would be ok too but it's fast in it's own right, no need to cross. Overall Ciskei is great for taming any long fowering sativa. I just finished a bag of Zamaldelica crossed to it and had a Celestial Temple Sativa cross in the past. It never fails.
