Looks like you have one seedling per pod. Should I assume that is by design? I've got my first DIY Greens gardens going and thinking that maybe I should be trimming out the extras in my Pac Choi, Tatsoi and Bok Choy pods? I did a 50/50 spit on the all lettuce side, 50% singles & 50% multiples, just to see what works best for me, knowing that folks have differing opinions on same. Thanks for any input!
