I finally finished my basement sump/refugium and put a few Mangroves in the refugium section. I know they take a while to grow but I was wondering how long they take to get started? Each has a little shoot about 1/2 inch sticking out, but they seem to be the same size as when I put them in there about a month ago. I have decent lighting as my chaeto is growing at a nice pace. I have Red Mangrove Propagules. They are each roughly 5-8 inches tall.
