>>1764006No idea what's the cotyledons on the cress anatomy specifically. Is it the leaves on the very top of their heads that look rounded? If so, I assume pic related isn't fully done yet since the leaves didn't fully expand? Normally I know when other plants are done germinating, but not these things since I'm new.
>>1764009You can grow it on some weird flat thing, yes, but I'm just following what the instructions read on the packaging. They just failed to mention when to remove their lid that keeps them moist.
