No, not really.

That's about what most of those tanks you like have on them.

I've had it grow pretty flat at 2 watts a gallon. It grows faster at higher
light, but that's not always a good thing with this weed. It'll run up if
it's shaded, crowded.

I use one or the other. I seldom take to mixing. MH's => open top tank.

It's about a little over 2 watts a gallon, not that much.

2x 55 watt or a single triton T-8 and one 96 watt 5000K PC.
