From seed I'm going to have to go with these 3 even though there are so many to list.
1. Mr. Nice Super Silver Haze
2. Serious seeds Kali mist
3. Mr. Nice NL5xHaze
I would put chem dog, sour d and og kush as my top 3 but I haven't, IMO seen any IBL's/bx's seeds that hold up to the original clone onlys. To many variations and unstability.
Skunk #1 is definitely a building block of many great strains today 100% totally agreed.
It is known to breed very true for desired & selected traits such as mold resistance & yield, ect. Many well known seed companies have used Sk #1 males for their F1 crosses. It is probably one of the most stable & important strains ever produced in Cannabis breeding.
Just wondering if you mean old stock Sensi Star. Jusy grown out some of the latest feminised Sensi Star from Paradise and wasnt too impressed. They still had some of the smell its famous for but the potency wasn't a patch on what I remember plus the yield was extremely poor. Had three nice females to compare but none were like the old sensi star.
Mine is
1. Malawi Gold
2. UK Cheese
3. Kali Mist
