Haha- most of those seedlings are tomatoes my gf is starting, though I have a couple rows of canna in there.
Just to note- 5 out of 5 S. African Kwazulu seeds from World of Seeds via Seedsman popped up in TWO days!! -in boiled well-water soaked jiffy cubes in large dome with common seedling heat mat underneath, and a Feit-brand LED spectrumed for vegetating shining (usually) through a thin blue silicone cooking pad (to dull the light, and the heat of the light resting on dome.
But- yes- those stretchers need to be buried up to their “collar”, or moved to greenhouse- maybe both. Going to move Kwazu and the 2/5 Freakshow I popped under the t-5 setup in my hottub-to-winter-hothouse conversion pictured below (have moved lights around a bit, and the T-5s are in the middle. Two led bars are on either side; also I like posting full-size pics because, at least on my phone, it allows me to zoom in, whereas thumbnails when expanded have a terrible pixelation. Pretty proud of this crazy setup. More a transistion space for most)
