all of my genetics are F2s, made from F1s that were bought from the original breeder. no knock offs for me unless it's something special!
i'm currently smoking, afghani #1 (it's just ok), a sativa pheno of super silver haze (lovely), skunk #1 (i keep forgetting how much i love this genetic) and malawi gold! i'm very impressed with the malawi and will be growing her out again with the intent of letting them flower for 75 to 90 days instead of my usual 60ish! it's a sativa dominant and all the trichs were clear at 60 days. i needed the room so i cut them!
i had so much good pot back in the day, that i only grew the malawi out once! i made some F2s and didn't touch them for 15 years or so. i'm glad i decided to grow out all of my genetics once more to find the cream of my genetics!
