Leggy: good for blondes, not tomatoes

The cherry tomatoes are growing pretty remarkably. You couldn't even really see them in the picture taken last Thursday:

But now...well...if you squint, you can kinda see them...they're those things in the corners. See?

Alright, they're not huge. But it's still pretty impressive, for a long weekend's worth of growth, don'tcha think? I was pretty amazed when I came in this morning.

I'm a bit worried, though, that even 90W of LED power isn't enough for them. This seedling's looking a bit leggy. 

Maybe I'm just being an overly attentive parent. Maybe it's just going through an awkward phase. But its sister doesn't look so lanky. Why can't you be more like your sister?

 

Across the cube, the lettuce has sprouted and is on its way. I took this picture right after watering. It's kinda pathetic what happens to seedlings at this stage. A gentle soaking will knock them over.

It's partly because they're inside. If they were outside and had to contend with breezes, they'd develop stronger stems. I've bought some fans to get some airflow on them, and the cherry tomatoes, too. Not sure it really matters for the lettuce, but weak stems on a tomato plant might have more severe consequences. Might the stems snap under the weight of the tomatoes? I don't really know, but it seems like a reasonable precaution to get a breeze on them.
