wait... you only have 1 bulb?
Yeah if it is single fixture, the plants will struggle, especially with 18000k bulbs.
lets just say i did learn a valuable lesson here. it says on the box that its at 80 on the LUX and its relative power is at its highest(100%) at the 430 wavelength
im kinda low on funds as far as the lighting systems.. would the plants hold up untill after may? prom season and im strapped for cash
2WPG is pretty subjective... and I would say incorrect. Java ferns will grow with far less than 2wpg in a medium sized tank.
18000K is a little high. 6500-10000K would be a much better range for them.
