Sown in August these Aloinopsis seedlings looked weak and grew extremely slowly for such a long time. Now something triggered the new growth (sudden increase in sunlight? ;) ) and you can see how happy they are. New leaves, more texture, even the first "teeth"!
Below some random seedlings mess you can find on my windowsill... XD
(Titanopsis primosii and Stomatium alboroseum 'rubrum', which has nothing rubrum to it)
