I have two led stripes 25cm long. They can be dimmed, are for aquaristik purpose and are of a good quality.
And before we left for holidays, the swimming plants (not ceratopteris) grew under the light very fine. I think it was the humidity unter the acrylic glas… I told my “fish home service” not to feed in that tank. So nobody lifted the acrylic glas for about two weeks …
The time before, I lifted the cover about every day to look after dragonfly larves, to feed the caridina simoni a bit.
