Wow, this is something new to me. you germinated the seeds in a tray with only 1 inch of soil mix. soon after cotyledon, you moved the seedlings to a cell tray, which is again a tiny cup. Meaning, you will move them one more time after they grow a little more?
Don't you think that moving the plants repeatedly can damage those tiny roots and may disturb their growth??
I have seen some people doing three times transplanting (germination->cell->pot->final position). I may skip potting when it warm this spring but it’s a gamble. I do this mainly because I have limited space and amount of seeds (10 seeds in a pack for rare varieties … ) 😅 If I have plenty of both, I think I start from cell tray and thin out plants. At least it works fine for me for the last years but I must do AB test 😊
