With regards to how long I can extend observations I am unsure.
The point of speeding things up was to chuck the ones I do not want, to make room for others that I wish to grow.
While extending the observation might be a cool idea, my initial plan was to treat all seedlings with GA next year so I can see all their faces then pick winners from each cross as early as possible.
I realize that first year flowers may not be wholly representative. But, in crosses where you want a specific color e.g. Red x Yellow, and you only want red seedlings then I doubt a seedling will change color entirely in future years, so I would feel safe throwing away all the yellows in year1.
I will ponder what to do all winter and come to a decision in spring. I can definitely buy a few more planters, but not so many (I have seen more nice seeds online, and if my own crosses bear seeds will want to grow some of those, aswell). But for the experiment to continue I would need to keep all 5 planters going for fair comparisons. Right now those daylilies are taking up about 20 places that fresh seedlings can go into.
