Rhinoman hit it on the head.
You may as well ask 100 people who the prettiest girl is.
May need to re-phrase the question.
Rhino also is correct that you cannot pick a winner based on appearance. If your goal is truely to find the best, you must compare the finished products in a trial by fire ;-)
That means you take cuts of ALL the girls and only keep the one(s) you choose after harvest.
Your priorities may be different, but for most here it is:
- Potency (pure strength, how much you smoke to get the effect you seek.)
- Quality of the high (Up, soaring, couch-lock, med user seeking pain relief, etc.)
- Yield
- Duration of Flowering
- Vigor/health, resistance to common problems (mold, pests, etc.)
- Anything else (appearance would be way down here)
If you seek a Kush pheno, then my experience is that you must be careful of jumping to conclusions based on appearance.
I should be harvesting in 2 or 3 weeks, so I will comment on how my assumptions did compared to how the plant smoked after I get to start testing them.
