What about Jeff's Gloss lawn with a huge 1.5 watts/gal?
 I've personally grown more Riccia at 2 watts/gal than I *even* want to try
estimate for 7-8 years now. Even the sinking type of Riccia. I've had plenty
grow attached on the bottom also at these levels. Gloss does just fine too.
Red Caboma does very well also at this light level. 

Generally, the more light added to Gloss and Riccia the better up to say
4-5watts/gal these plants will do. It can be done with less light
though..........and this can stop those 2x a week trimmings and make it
every 2 weeks instead. Something to ponder.........how fast you want to
drive the growth rates.

Gloss does well with no vertical growth generally, if you give it room, some
light, and let it go. As Steve says..........................PATIENCE is
what it takes. It's nice to see folks worrying because that means they care
about the hobby and what they are doing! Jeff's stayed very low using low
lighting and so does mine with MH's. I just nip off the vertical growth if I
ever see it. Stuff grows right back.
