[stmoo]

can anyone help me, i am not sure which type of lighting to get for my 3ft tank for plant. Pl ligtht or Fl light. and where i can get them at a cheaper price.

depends on how many Watt/USG you want to achieve.

For high light planted tank (with riccia etc), 3W/USG (or more?) is what most practises. In this case, PL begin more compact, will be a good choice. I have 4 x 36W PL for my 3ft.

For lower light planted tank, you can either have FL or fewer PL to ahieve 2 - 2.5W/USG.

fl and pl are of the same technology.
pl has the advantage of being more compact so you can pack more light into a particular sized light hood.

Lorba, Where do you get your 4 x 36 PL and how much does it costs ?
