About 3 weeks ago I germinated two Mimsoa Tenuiflora seeds using the 1h hot water bath then wet tissue method. I was really excited when they started germinating

I live in a zone 9 european country well known for it's rainy and unpredictable weather, so my plants will mostly depend on lights and will probably stay indoors until they start tickling the ceiling. Anyway! I don't have any real light set up yet, i plan on soon making a space bucket or dedicating a closet to them and germinating more seeds. So the two plants i have now are feeding off whatever poor clouded sunlight hits my South facing window. One is about 3cm tall and the other about 1cm, both still only have their cotyledon leaves.
I've read a couple of nexus mimosa grow posts for grow advice, but i have a few questions.
I'm going to use a regular desk lamp for a little while as I get a better setup ready. Do they hae particular light cycles or will they accept as much as their given?
From the meh light they've gotten, are they doing alright or are they way behind? The mimosa grow logs on the nexus have plants that are about >3months old so they have the beautiful mimosa branches and leaves, so I've never seen pictures of how they progress from younger.
Do they have any special requirements at this age apart from love, light and room temp? Any advice would be much appreciated!!
Peace and Love
