Well, probably does not quite meet your criterion, but many pond plants that grow in full sun are attempted in aquariums, and fail. Not enough light.

Water Lettuce is sort of marginal in this respect. People call it 'dwarf' water lettuce when it stays small and flat at the surface of a tank with bright light. But in a sunny pond it grows to its proper size, tall and wide, like a head of lettuce. I have not tried it with LED.

 

Yes, I could not keep water lettuce in good shape indoor. I have to keep them outdoor exposed to sunlight. It's not the most demanding plant though.

I have no luck with glosso although for some people they grow like wild fire. So, to me it's the most demanding plants I have ever tried.

 

Water lettuce under optimal conditions can reach 60 cm diameter. Not too far from my living place (2 hours drive) there is a thermal stream where it reaches such proportions each summer. Probably it does the same in many tropical areas where the water is rich in nutrients.

 

1/ IMO ...dwarf baby tears, glosso

2/ absolutely. BML, Finnex

 

Thanks for the reponses.

3) If you have successfully grown high light plants using LEDS can you let me know of the tank height ?


4) As well anyone consider Dwarf Hair Grass a plant that requires high amounts of light and has this been successfully grown with LED and at what tank height?
