Well... I had a small cluster that thrived under a single bulb t8 until 2months of quarentine was over, then moved to under a high power t5..
It has since replicated twice.. still a small stalk, but appears to be thriving..
(t8 was a dual bulb t8 eclipse 20 hood, t5's are 220w 4 bulb with a great reflector)
Not sure if that is what is spec'd for it, but it's working
(was a hitchhiker coral of all things..)
