I am thinking of creating a new layout for my aquarium an Iwagumi style.
Plants that are intend to enter HC Cuba and Eleocharis Acicularis. However, I do not know if I have enough light for this plants.

The specs of my tank:

60cmx35cmx40cm (20G / 84L)
Pressurized CO2 (Inline Injector)

As the light got two possibilities:
a) 1x36W PLL 6500k (with an excellent reflector);
b) 2x24W T5 6500k.

I not looking for an high light aquarium, because my previously scape had a 70W MH lamp and i was always pruning the plants.

What is your advice for growing cuba? Is the light system described in a) enough? it will grow healthily and compact? or is it better the light system described in b)?
