Temps are warming up and they're getting some proper light finally.
Still slow progress, but the 2nd set of leaves are forming and added Mycoroot, so hopefully that helps them speed up.
Also put sticky traps out, have a lot of tiny flies/midges. Working well already n had a few stuck within 5 min. Can see one in the video hovering just above the Guerilla Glue lable and tonnes stuck to the sticky traps. If anyone knows a quick fix to get rid of them besides the traps, please let me know.
Height hasn't increased much, because I moved a lot of soil to the sides of the pots when I planted them in and as they stretch I fill it in & level the soil out, but they are definitely making progress and has definitely sped up a lot now that the sun is out and temperature is rising.
