I'm thinking of getting 2 x 36W PL light set for my coming 3x2x2 ft tank that I was hoping to get for my upgrading project.

With some calculation, 80% filled tank would be having 1 wpg. I was thinking if it is enough for my plants below.

Echinodorus angustifolius
Moss (Java, Taiwan, Singapore, Spiky, Stringy)
Java ferns (Windelov and normal ones)
Cryptocoryne beckettii
Vallisneria (not sure the exact one)
Some other plants that I have not ID yet

I think the light should be enough for these plants. Any advice is greatly appreciated.
