Diggerofdirt said: Out of 300 seedlings only 38 have made the cut. I mean watching keeping logs on for registration. Not a good ratio in my book.
Actually, I would be very happy with that ratio. I am just starting out (yr 2 of hybridizing) and if I get 1 or 2% of seedlings to make that 1st cut I will consider myself very fortunate. But perhaps it all depends on how many seedlings you are generating and how aggressive you are with culling early on.
That being said, I would only cull when i needed the space or to reduce my work load. If you don't need the space you might as well let more of them develop. Who knows, maybe an ugly duckling will have 50 buds and 8-way branching making it very useful for breeding purposes.
Now, imagine if you had 30,000 seedlings... with your ratio (12.7%), you would be keeping 3,800 seedlings.. that would be daunting indeed. In that case I imagine most would opt to keep fewer than 12.7% for observation... but who knows...
In short, if you have 38/300 that you see potential in... I think that's a huge number to work with
