Thx for sharing Khoon. Looks like you prefer covered water tray too. I noticed sphagnum moss causes moss and bad smell, much more than peat moss, esp under direct/indirect sun. I'm leading more to peat moss with water tray now.
I don't hv T5HO tubes, can't find anywhere nearby that sells them. Just using high efficient T5 6400k at ~4-6" from seed trays. Using timer to mimic additional 2hrs of noon sun that the seedbox didn't get. At least it works right now. Anyway, don't dare to compare to your work

. We're in diff league, I'm still amateur.
3rd experiment using ampullaria seeds, I'm comparing germination rate under FL and balcony outside. If results are similar, then I can simplify germination method further. Just too lazy to type right now.
