Davi thank-you so much for your insights! They definitely carry a LOT of weight with me! A bit surprised you didn't mention the third seedling-- when I saw the incredible saturation of the FFEs it immediately caused me to drop to my knees. Perhaps that's blinding me to flaws...
I've never felt the need to grow mega-thousands of seedlings, certainly not in terms of number of crosses. While I wouldn't mind being able to grow a few more seeds per cross, I totally agree-- there is no need to make a huge number of crosses and not good to get the volume of work unmanageable... I've got a plenty of targeted crosses to keep me busy and hopefully bring a few good results...
