Hi
I am thinking of a 30 inch long tank (20 gallon long) with driftwood and only Java fern but think the lighting might be on the weak side.

I only have an Led bulb which in theory equals 60 watts of light.

Can only 1 bulb grow Java fern?

This is inly beginning pic, I intend to add more wood.

Thanks
