Growing Ludwigia Sp Guinea, what's the trick?

Anybody growing Ludwigia Sp Guinea over here?

Any success in growing them with big and very red leaves?

Hi bro,
Yup, lots of iron and light is needed.

Hi bro,
Yup, lots of iron and light is needed.

Can share what's the lighting you are using for them? How deep is your tank, or rather how far is your light bulb away from the plant?

I am using 150watt MH, hung above water surface of about 10 inch to a feet, for a 2ft deep tank. Effectively, the light source is about 2feet away from the top of the plants. I am maintaining a temperature in the tank ranging from 23.6 to 24.4 C.

I am starting to dose 5ml of Seachem Iron once every 3 days, for a 200 litres tank.

I can't really get them real red. BTW, they have been with me for about 2 weeks or so. Have not trim them yet., but they seems to be growing fast / tall from what I observed. They aren't these fast when I had them a few years back.
