I recently traded my 29 gallon for a 30 gallon. I have completed the intital planting including riccia. My question is, will riccia grow fine with 72 watts of pl lighting in a 30 gallon or is it not enough? I dont think its genuine 72 watts as it is 2 36 watt pl. Doesnt that mean that the intensity is only like 1.6 watts per gallon? I was looking at the ahsupply 96 watt kit and almost bought it, but I thought id ask here first. I was thinking of going brighter just to make sure the light reaches the substrate intense enough for the riccia to grow. The substrate is about 3 inches in height.
