I was trying to use Mi5 as my nimber 1 plant in my SOG, bubbly tank grow, I wanted the grow to be the pheno with single cola cause I thought it would be the best yield for my grow. I went to F3 with just taking the single cola types to rebreed. I never got a majority of single cola types. I then crossed it out to snowryder and now I have 80% single cola seeds. After only F2. I will keep going with it maybe I can get it over 90%.
