Bright Light Plants

[Gnatfish]

What lighting requirements do plants like Glosso and Riccia need? How many WPG? Is 2.3 WPG enough?

Also how many WPG is bright light?

Depends on the size of the tank but for normal sized tanks say over 10g then 2WPG in the golden rule, under which you'll be able to grow almost anything. It does also depend on the depth of the tank but unless this is a huge tank its probabyl not overly deep so 2WPG or over and the glosso should do fine

2.3 wpg in a 72 l. is borderline to guarantee success, particularly with glosso I'd suggest. What tubes are they? Do you have two or three? With just two you may have difficulty. Ensure you have decent, clean reflectors.

If you keep a stable 30ppm CO2 and ideal nutrient levels then you stand the best chance. You'll soon know because your glosso will grow upwards is lighting is too low. I assume you have a nutrient-rich substrate?

The pinned lighting thread has a basic description of lighting levels.

The WPG rule used normal output fluorescent lighting. With t-5/individual reflector or high output compact fluorescent the light output is greater per watt than n.o. so that 2.3 WPG of pc would give you more foot/candles on the tank bottom than 2.3 WPG of n.o.

This is for a 10g tank that is empty. Being annoying it only has 1x15 watt tube. But if i can find some end caps for a 8W T8 then i will add that (can't find any anywhere!!!!!!help..). This tank will have laterite and gravel, with Co2.

I'd suggest you'll need a minimum of 30-40W T8 with reflectors in a 10g to be able to carpet glosso.

mmm...ok. What about Riccia?

 

[George Farmer]

A little less light probably, I'm not too experienced with Riccia - too much maintenance for me!
